Miyawaki TB52 Temperature Control Steam Trap

Manufacturer: MIYAWAKI Inc.
Model: TB52

Features

Complete steam containment
The temperature control trap operates with an adjustable subcooling of condensate. Thus maintaining a certain condensate level in the trap. This mechanism provides a 100% tight sealing and effectively prevents steam loss during operation.

Suitable for high pressure, high temperature ranges and superheated steam

Superb durability

The MIYAWAKI SCCV (Self Closing and Centering Valve) System has the effect of increasing durability by achieving soft closing during operation. Consisting of a free rotating valve that is centered and guided by the condensate flow, hence perfectly fitted in the valve seat even under extreme conditions of high pressure applications. This significantly reduces wear and erosion of the valve components.

Quick startup
Swiftly discharges the initial cold condensate and air.
Also fulfils the function of an air vent.

Energy saving effect
A significant energy saving effect is achieved by controlling the temperature of discharged condensate.

With low operating noise and very little flash steam

Typical applications

Suitable for steam main lines, trace lines, and other such applications.

*It is possible to change the standard factory set temperature. Specify the operating pressure and set temperature.
*Please refer to the installation manual how to adjust the set temperature.

Discharge Capacity

TB52

⊿t is the difference between the temperature of a temperature control trap when the valve is initially opened and condensate temperature. The temperature difference (⊿t) upon the initial passage of air is great, and indicates that the flow rate will also increase.

*  Curve1 shows the trap’s maximum capacity when discharaging cold condensate.
**Curve2 shows the trap’s maximum capacity when discharaging hot condensate at a temperature of 10°C (18°F) below the adjusted temperature of the trap.
