Body: ASTM A-536 Cast Iron / Valves : Bronze Surface covered with Teflon, Stainless steel Trim Set / Pilot control valve and system: Bronze ASTM B62 and Stainless steel 303 inner parts ** Connection Type: Flanged / Pressure :16-25 Bar / Working Temp.: +4ºC , + 80ºC *** This valves using for the preventing damages which cause from the pressure in fire pump systems. Generally fire protection systems use the diesel pumps and electrical motors. In that systems relief valves are preferred. **** Application Areas: In systems which has diesel or electrical high pressure fire fighting pumps.

Test and Drainage Valves / Body: Brass ( Forged ) / Ball : Brass / Gasket : PTFE ** Connection Type: Threaded or Grooved / Working Pressure: 300 PSI ( 20,6 Bar ) / Working Temp.: -10ºC , +120ºC / Working Test Pressure: 600 PSI (61,8 Bar) *** In sprinkler systems, these valves are used for the testing systems and drain the unnecessary fluids from the systems. Advantages: They have sight glasses in their body,single valve is sufficient to drain the line. For choosing the test and drain valves, users should pay attention to line diameter.
