CONSTRUCTION:
The blowdown valve comprises two main functional units:
- valve body,
- pneumatic actuation ODM2, hand lever ODM1.
Valve body is made of carbon steel. Valve seat is made from rolled stainless steel: H17N2. Valve plug is made from 4H13 material and sealed in the bonnet by means of a packing box. Pneumatic actuation unit includes a springloaded pneumatic actuator and a yoke. The spring thrust provides for efficient valve shut-off tightness.
