In a normal state, pressure P1 inside the line is applied to the connection, and the pressure P2 of the air intake is atmospheric pressure.
P1 is higher than P2 (P1>P2), and the valve is closed by this differential pressure.

Operating state
If the pressure in the line becomes negative, the pressure P1 at the connection becomes lower than the pressure P2 at the air intake (P1 The valve is opened by this differential pressure.
The valve is closed when the air flows in the line and the pressure in the line is increased. It will return back to Nomal state.

Capacity Chart

Tables of calculation for steam

RE20 (REH20, REC20)
RE20L (REH20L, REC20L)

How to select the size of a PRV correctly?

If the ratio between the downstream pressure p₂ and the inlet pressure p₁ is larger than 0.577 (non-critical flow), the available steam flow amount on the downstream side will be reduced. To get the maximum available downstream flow amount, the maximum steam flow from Table 1 must be multiplied with the calculation factor A. To get the Factor A see the Diagram 1.

Check if the requested steam flow matches the downstream side using Table 2 (page 16) for flows under 40 m/s. Choose the size based on barg pressure. If downstream piping is 1–2 sizes larger than the PRV inlet, you’re good. If the size difference is over 2, increase the PRV size. Keep the difference within 2 sizes!

Example of calculation

Operating data:

p₁ = 9 barg = 10 bar_abs
p₂ = 6 barg = 7 bar_abs
Steam flow G = 1,100 kg/h

Search for the necessary size of the PRV in accordance with p₁.

Table 1 shows 1,312 kg/h for size DN40 (1½”).
bar_abs = 0.7 (i.e., larger than 0.577)
Factor A acc. to Diagram 1 = 0.96
Max. available steam flow G = 1,312 kg/h × 0.96 = 1,259 kg/h.

Miyawaki REH20L-M With Pulse Line For Steam

kvt part2 — Wed, 28 Oct 2020 04:37:05 +0000

Manufacturer: Miyawaki Inc.
Model: REH20L-M

Features

Pressure reducing valves for steam

These are automatic valves that reduce the steam supply pressure to the certified pressure for the device in use, and keep it steady.

Operating features of direct acting pressure reducing valves

Pressure changes on the secondary side are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to keep the pressure on the secondary side at a set level.

Due to carefully selected springs a wide range of pressure applications is available.

Maximum pressure reduction ratio 25:1

As option the valve can be equipped with a pressure gauge on the valve body.

Uses

Perfect for cleaning devices, foodstuff devices, and other forms of compact steam equipment.

How to select the size of a PRV correctly?

Example of calculation

Operating data:

p₁ = 9 barg = 10 bar_abs
p₂ = 6 barg = 7 bar_abs
Steam flow G = 1,100 kg/h

Search for the necessary size of the PRV in accordance with p₁.

Table 1 shows 1,312 kg/h for size DN40 (1½”).
bar_abs = 0.7 (i.e., larger than 0.577)
Factor A acc. to Diagram 1 = 0.96
Max. available steam flow G = 1,312 kg/h × 0.96 = 1,259 kg/h.

Steam flow in accordance with Table 2 at 6 barg = 1,720 kg/h for DN65.

Conclusion:

The PRV with an inlet size of DN40 and increase of the pipe size to DN65 at the downstream side will be suitable for a flow amount of 1,100 kg/h at the given pressures.

Manufacturer: Miyawaki Inc.
Model: REH20L

Pressure reducing valves for steam

These are automatic valves that reduce the steam supply pressure to the certified pressure for the device in use, and keep it steady.

Operating features of direct acting pressure reducing valves

Pressure changes on the secondary side are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to keep the pressure on the secondary side at a set level.

Due to carefully selected springs a wide range of pressure applications is available.

Maximum pressure reduction ratio 25:1

As option the valve can be equipped with a pressure gauge on the valve body.

Uses

Perfect for cleaning devices, foodstuff devices, and other forms of compact steam equipment.

How to select the size of a PRV correctly?

Check the operating data:

Inlet pressure p₁
Requested downstream pressure p₂
Requested steam flow

Check the requested steam flow in the capacity chart on page 15. Select the necessary size of the PRV. Table 1 shows the maximum available steam flow in kg/h at a given inlet pressure, if the ratio between the requested downstream pressure p₂ and the inlet pressure p₁ is lower than 0.577 (critical flow). Pay attention that the steam pressure is shown as bar_abs!

Example of calculation

Operating data:

p₁ = 9 barg = 10 bar_abs
p₂ = 6 barg = 7 bar_abs
Steam flow G = 1,100 kg/h

Search for the necessary size of the PRV in accordance with p₁.

Table 1 shows 1,312 kg/h for size DN40 (1½”).
bar_abs = 0.7 (i.e., larger than 0.577)
Factor A acc. to Diagram 1 = 0.96
Max. available steam flow G = 1,312 kg/h × 0.96 = 1,259 kg/h.

Steam flow in accordance with Table 2 at 6 barg = 1,720 kg/h for DN65.

Conclusion:
The PRV with an inlet size of DN40 and increase of the pipe size to DN65 at the downstream side will be suitable for a flow amount of 1,100 kg/h at the given pressures.

Miyawaki RE20L With Pulse Line For Steam

kvt part2 — Wed, 28 Oct 2020 03:12:05 +0000

Manufacturer: Miyawaki Inc.
Model: RE20L

Features

Pressure reducing valves for steam

These are automatic valves that reduce the steam supply pressure to the certified pressure for the device in use, and keep it steady.

Operating features of direct acting pressure reducing valves

Pressure changes on the secondary side are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to keep the pressure on the secondary side at a set level.

Due to carefully selected springs a wide range of pressure applications is available.

Maximum pressure reduction ratio 25:1

As option the valve can be equipped with a pressure gauge on the valve body.

Uses

Perfect for cleaning devices, foodstuff devices, and other forms of compact steam equipment.

How to select the size of a PRV correctly?

Example of calculation

Operating data:

p₁ = 9 barg = 10 bar_abs
p₂ = 6 barg = 7 bar_abs
Steam flow G = 1,100 kg/h

Search for the necessary size of the PRV in accordance with p₁.

Table 1 shows 1,312 kg/h for size DN40 (1½”).
bar_abs = 0.7 (i.e., larger than 0.577)
Factor A acc. to Diagram 1 = 0.96
Max. available steam flow G = 1,312 kg/h × 0.96 = 1,259 kg/h.

Steam flow in accordance with Table 2 at 6 barg = 1,720 kg/h for DN65.

Conclusion:

The PRV with an inlet size of DN40 and increase of the pipe size to DN65 at the downstream side will be suitable for a flow amount of 1,100 kg/h at the given pressures.

Capacity Chart

How to use selection chart (example)
To reduce the pressure of 800kg/h (1764lb/h) of steam from 0,8MPa to 0,5MPa (116psig to 73psig)

1. Find the point at which the primary side pressure 0,8MPa (116psig) curve and secondary side pressure 0,5MPa (73psig) horizontal line intersect.
2. Trace a vertical line from the point where they intersect, and look for the smallest-sized product where the steam flow rate is 800kg/h (1764lb/h) or more at the point where the vertical line you have traced intersects the horizontal size lines.
3. In this case, the pressure reducing valve with a size of 1 1/2” is optimum.

Features

Self-acting pressure reducing valve for steam

This valve reduces the steam supply pressure to a defined outlet pressure and keeps it steady, even under downstream fluctuations . The valves needs no seperate energy source.

Operating features of direct acting pressure reducing valves

Pressure changes on the downstream side are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to keep the pressure on the downstream side at set pressure.

Wide range of pressure reduction

Due to carfefully selected springs an outstanding reduction ratio of 25:1 is achieved.

Diaphram free design

The valve operates with an O-ring sealing and a piston design. Due to this design, no daiphragm and no external sensing line is required.

Superb durability

Highly durable and carefully selected components, a 360° free rotating, conical plug and the lack of a sensitive diaphragm ensure outstanding lifetime of this valve.

Options available

– additional pressure gauges
– tailored connections for special applications
– softsealing for leakage class VI

Typical applications

Perfect for all applications with medium to high steam flow or high reduction. In particuliar power plants, chemical and petrochemical process applications, ships, food and beverage plants, and other similar installations of of compact steam equipment.

How to select the size of a PRV correctly?

Check the operating data:

Inlet pressure p₁
Requested downstream pressure p₂
Requested steam flow

Example of calculation

Operating data:

p₁ = 9 barg = 10 bar_abs
p₂ = 6 barg = 7 bar_abs
Steam flow G = 1,100 kg/h
Search for the necessary size of the PRV in accordance with p₁.

Table 1 shows 1,312 kg/h for size DN40 (1½”).
bar_abs = 0.7 (i.e., larger than 0.577)
Factor A acc. to Diagram 1 = 0.96
Max. available steam flow G = 1,312 kg/h × 0.96 = 1,259 kg/h.

Steam flow in accordance with Table 2 at 6 barg = 1,720 kg/h for DN65.

Conclusion:
The PRV with an inlet size of DN40 and increase of the pipe size to DN65 at the downstream side will be suitable for a flow amount of 1,100 kg/h at the given pressures.

How to select the size of a PRV correctly?

Check the operating data:

- Inlet pressure p₁
- Requested downstream pressure p₂
- Requested steam flow

Check the requested steam flow in the capacity chart on page 15. Select the necessary size of the PRV. The table 1 shows the maximum available steam flow in kg/h at a given inlet pressure, if the ratio between the requested downstream pressure p₂ and the inlet pressure p₁ is lower than 0.577 (critical flow). Pay attention that the steam pressure is shown as bar_abs!

Now, check if the requested steam flow is available on the downstream side. Use the capacity chart (Table 2) on page 16 to find the maximum downstream steam flow in kg/h, assuming a steam velocity of up to 40 m/s. The steam pressure is listed in barg, so choose the corresponding size. If the steam piping on the downstream side is 1–2 sizes larger than the PRV inlet size, the selection is correct. However, if the inlet size from Table 1 (page 15) differs from the downstream size in Table 2 by more than 2 sizes, increase the PRV inlet size. Keep the size difference between the inlet and downstream piping within 2 sizes.

Example of calculation

Operating data:
p₁ = 9 barg = 10 bar_abs
p₂ = 6 barg = 7 bar_abs
Steam flow G = 1,100 kg/h

Search for the necessary size of the PRV in accordance with p₁.

Table 1 shows 1,312 kg/h for size DN40 (1½”).
bar_abs = 0.7 (i.e., larger than 0.577)
Factor A acc. to Diagram 1 = 0.96
Max. available steam flow G = 1,312 kg/h × 0.96 = 1,259 kg/h.

Steam flow in accordance with Table 2 at 6 barg = 1,720 kg/h for DN65.

Conclusion: The PRV with an inlet size of DN40 and increase of the pipe size to DN65 at the downstream side will be suitable for a flow amount of 1.100 kg/h at the given pressures.

Miyawaki RE20 Direct Acting For Steam

kvt part2 — Sun, 11 Oct 2020 07:26:45 +0000

Manufacturer: MIYAWAKI Inc.
Model: RE20

Features

Self-acting pressure reducing valve for steam
This valve reduces the steam supply pressure to a defined outlet pressure and keeps it steady, even under downstream fluctuations . The valves needs no seperate energy source.

Operating features of direct acting pressure reducing valves
Pressure changes on the downstream side are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to keep the pressure on the downstream side at set pressure.

Wide range of pressure reduction
Due to carfefully selected springs an outstanding reduction ratio of 25:1 is achieved.

Diaphram free design
The valve operates with an O-ring sealing and a piston design. Due to this design, no daiphragm and no external sensing line is required.

Superb durability
Highly durable and carefully selected components, a 360° free rotating, conical plug and the lack of a sensitive diaphragm ensure outstanding lifetime of this valve.

Options available

– additional pressure gauges
– tailored connections for special applications

Steam Flow Rate

Tables of calculation for steam

RE20 (REH20, REC20) RE2OL (REH20L, REC20L)

How to select the size of a PRV correctly?

Check the operating data:

- Inlet pressure p1
- Requested downstream pressure p2
- Requested steam flow

Check the requested steam flow in the capacity chart on page 15. Select the necessary size of the PRV. The table 1 shows the maximum available steam flow in kg/h at a given inlet pressure. If the ratio between the requested downstream pressure p2 and the inlet pressure p1 is lower than 0.577 (critical flow), pay attention that the steam pressure is shown as bar abs!

If the ratio between the downstream pressure p2 and the inlet pressure p1 is larger than 0.577 (non-critical flow), the available steam flow amount on the downstream side will be reduced. To get the maximum available downstream flow amount, the maximum steam flow from Table 1 must be multiplied with the calculation factor A. To get the Factor A, see Diagram 1.

Now check whether the requested steam flow will be available on the downstream side. The capacity chart (Table 2) on page 16 shows the maximum steam flow on the downstream side in kg/h considering a steam velocity not higher than 40 m/s. Pay attention that the steam pressure is shown in bars. Select the corresponding size. If the size of the steam piping on the downstream side will be 1–2 sizes larger than the inlet size of the PRV, the selection of the inlet size will be correct. But, if the difference between the inlet size found in Table 1 at page 15 and the downstream size in Table 2 at page 16 will be larger than 2 sizes, the inlet size of the PRV must be increased. The difference between the inlet size and the pipe size at the downstream side should not be larger than 2 sizes.

Example of calculation:

Operating data:

- p1 = 9 barg = 10 bar abs
- p2 = 6 barg = 7 bar abs
- Steam flow G = 1,100 kg/h

Search for the necessary size of the PRV in accordance with p1:

Table 1 shows 1,312 kg/h for size DN40 (1½”).
p2 / p1 = 0.7 (i.e., larger than 0.577)
Factor A acc. to Diagram 1 = 0.96
Max. available steam flow G = 1,312 kg/h x 0.96 = 1,259 kg/h

Steam flow in accordance with Table 2 at 6 barg = 1,720 kg/h for DN65.

Conclusion: The PRV with an inlet size of DN40 and an increase of the pipe size to DN65 at the downstream side will be suitable for a flow amount of 1,100 kg/h at the given pressures.

Capacity Chart
The Table 1 shows the maximum available steam flow amount of the pressure reducing valve at a given inlet pressure, if the ratio between the downstream pressure p2 and the inlet pressure p1 is lower than 0.577 (critical flow). Pay attention that the inlet steam pressure p1 is shown as bar abs.

TABLE 1

Capacity Chart

The Table 2 shows the maximum available downstream steam flow amount of the pressure reducing valve at the requested downstream pressure p2. Pay attention that the steam pressure p2 is shown as barg.
