Fushiman TL10H type temperature control valve

Manufacturer: Fushiman Co.,LTD.
Model: TL10H
| Model | Nominal diameter | Pressure | Temperature setting | Body Material | Connection |
|---|---|---|---|---|---|
| TL10H | 15–50 | Max. 1.0MPa | 10 to 110°C | FCD | Flange (screw-in temperature sensor) |
Features
Compared to conventional bellows-type (single-seat valves), it offers a larger capacity with less seat leakage, and is also compact and lightweight.
The actuator can be easily attached and detached from the valve body, allowing wide-range temperature adjustment with a single actuator and capillary tube.
Designed to be less affected by fluid pressure.
The capillary tube uses a liquid expansion system, so the installation angle is flexible.
The fluid inside the capillary tube and actuator uses water or alcohol-based liquid, so no special disposal by a waste treatment contractor is required.

Example of using the selection chart
Specifications: Fluid – Saturated steam
Primary side pressure: 0.3 MPa
Flow rate: 150 kg/h
① Assume the allowable valve pressure drop ΔP is 0.05 MPa. Determine the intersection point between the secondary side pressure 0.25 MPa (0.3 – 0.05 MPa) and the primary side pressure 0.3 MPa.
② From intersection point A, draw a vertical line downward and find point B where it intersects with the flow rate of 150 kg/h.
③ Point B falls between nominal diameters 25 and 32, so select the larger one, which is 32.
Notes:
Plan so that the flow velocity at the primary pressure side is 30 m/s or lower.
The allowable valve pressure drop ΔP (pressure difference across the valve) should be 0.2 MPa or less.
