Aq20/A28X Air Compressor Safety Relief Valve with Stainless Steel/Brass/Carbon Steel Material
Product Description
DESCRIPTION Provided as safety device for protection against excessive pressure in stationary and moveable gas cylinders and pressure vessels. Approved for air and similar gases. Working temperature: -40°C / -40°F (233K) up to +200°C / +392°F (473K), suitable for horizontal installation" OPERATION 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. SPECIFICATIONS Bonnet connection: Execution: Connection type: Operation: MEDIA Gases, Air CONSTRUCTION Standard safety valve FPM valve seal for fluids, open bonnet, with discharge holes Inlet: male thread type G (BSPP) acc. to ISO 228/1 OPTIONS
Available options - on request only: · discharge holes with protection cap · stainless steel spring - material 1.4571 · external parts nickel plated
