SAFETY VALVE BRASS PROPORTIONAL THREADED HEROSE 06205
Material:
brass CW614N B 249 UNS C38500Dimensions:
DN 1/2" - 1 1/4"DESCRIPTION
Automatic pressure releasing valve which opens proportionally to the pressure increase.
Constant balance between opening pressure and spring force gives small flow and minimal fluid loss on discharge. Fully open at set pressure +10%.
When ordering a safety valve please let us know your requirements regarding capacity, media, temperature, inlet dimension and type of system.
Standard safety valve with FPM valve seal, open bonnet, with discharge holes, with lifting device Inlet: male thread type G (BSPP) acc. to ISO 228/1.
