Pressure Reducing Valve For Steam
Model
PIR-1F / PIR-2F
Series
Pressure Reducing Valve
Product Description
- The mechanism that automatically adjusts the pressure in pressure reducing valves uses the balance between the steam pressure and the adjustment spring.
- The steam flowing through the pilot valve is controlled by the balance between the adjustment spring and the secondary pressure.
- This steam causes the piston to fall and rise, which controls the amount of opening of the main valve.
