Pneumatic Y type Steam Trap&Drain Valve

Steam Trap&Drain Valve Applying to high&low pressure steam pipeline Cavitation-resistant Heat elimination structure

Fisher Pneumatic Diaphragm Operated Y Type Heater Drain Control Valve

Pressure range from ASME 150Lb ~ 4500Lb

Temperature range from -100°F ~ 1200°F

Design features:

1. Threaded bonnet, can be designed to be welded or removable structure          

2. Body and bonnet joint accurately machined.

3. Secondary throttling face design which reduces the erosion of sealing surface.

4. Intergral overlaying welding type seat.

5. Inclined stem and optimal runner design make the medium flowing as linear pattern.

6. Special heat emission plate design structure.

7. Electric or pneumatic actuator is optional.
