Overview
The Honeywell MCS Pop Relief Valve is ideally suited for instrument protection, farm taps, gas engines and process industry installations involving air and other gases.
Features & Benefits
Features & Benefits
- Minimum relief pressure setting: 1/2 PSIG (.04 bar) Maximum: 300 PSIG (21 bar)
- Maximum inlet pressure: 500 PSIG (35 bar)
- Rugged Construction - Body is high tensile strength gray iron ASTM A-12666 Class B for standard models. Cast ductile iron ASTM A-445-66 material is also available.
- Seat Discs are Buna N permanently bonded to the seat disc holder. The seat disc holder is die cast aluminum and the adjusting screw is machined aluminum, both are black anodized for corrosion protection.
- 302 Stainless Steel relief spring - All springs snap-fit into adjusting screw for ease of assembly.
- Stainless Steel screen is provided for protection against insects and other foreign matter.
