BRASS PROPORTIONAL SAFETY VALVE THREADED HEROSE 06205
TECHNICAL DESCRIPTION
Automatic safety valve, opening proportionally to pressure rise. The constant force between the pressure force and the reaction of the closing spring ensures a minimum flow, respectively fluid consumption when the valve is actuated. Full opening, at 10% overpressure of the valve setting. When ordering a valve, please inform us of your requirements regarding valve capacity, fluid type, temperature, inlet size and the type of system in which it will be used. Standard safety valve with FPM seat seal, open bonnet with unloading windows and forced opening device. Thread type G (BSPP) according to ISO 228/1 Used as a safety device in the event of excessive pressure rise in stationary systems and mobile gas cylinders and pressure vessels. Suitable for air and similar gases. Operating temperature: -20°C / -4°F (253K) up to +160°C / +320°F (433K), size d07 also suitable for horizontal installation.
WORKING FLUID / MEDIUM
Liquids, gases, steam.
EXECUTION
Only upon request:
- stainless sealing ring – stainless steel 1.4571.
- external nickel coating on the valve.
Dimensions: DN 1/2″ – 1 1/4″
