PVS 782



PVS type  slam shut valves  are pilot-operated relief valves in which the opening and the closing of the main plug is  controlled by a pilot device which is very sensitive to the variations of the in-line pressures.

The main features of such type of slam shut valve are the following:

  • Very high accuracy and rapidity of intervention (only 2% pressure);
  • Perfect seal up to pressures  very close to the setpoint  (contrary to what happens for the spring valves, the force on the plug in this slam shut valve increases when approaching the setpoint);
  • High outflow rate;
  • Reduced dimensions;


  • Non-corrosive fluids: (air, oxygen, nitrogen, helium, hydrogen, methane, propane, butane, etc.)
  • Intervention range : 1.5÷ 43 bar
  • Size DN= 1" - 1" 1/2 - 2" - 2" 1/2 - 3" - 4" - 6" - 8".
  • Flanging: ANSI 150-ANSI 300-ANSI 600, UNI PN 16, DIN PN 16
