Pressure Reducing Valve For Steam YNV PIR-1F / PIR-2F

PIR-1F / PIR-2F

  • 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
