Body: Ductile Iron / Stem,Springs: Stainless Steel / Disc: Brass or Aluminium or Bronze / Disc gasket or Disc washer : EPDM / ** Connection Type: Flanged or Grooved / Working Pressure: 300 PSI ( 20,6 Bar ) / Working Temp.: -10ºC , +120ºC / Working Test Pressure: 600 PSI (61,8 Bar) *** The wet alarm valve is designed for applications where the water is unlikely to freeze. The water staying pressurized in the pipes is released over the fire area after the sprinkler is activated due to fire. The pressurized water system is not only feed contionuously, but also fills in the retard chamber. After the chamber is filled, the pressure switch on the chamber is actuated.
