Fisher™ Type 63EGLP-16 Relief Valve
Fisher Type 63EGLP-16
Type 63EGLP-16 relief valve provides overpressure protection for LP-Gas, NH3 and other pressurized fluid storage tanks.
Compared to Multi-ported Direct Operated Relief Valves, they have lower installation and maintenance cost. Each Relief valve provides relief capacity of 10,540 SCFM air. Two relief valves protect up to 1574 sq ft of surface area (30,000 US Gal Stub tanks) and three relief valves protect up to 2581 sq ft of surface area (30,000 - 45,000 US Gallon tanks). The unique dual-pilot design allows for the removal of pilot for set point verification and maintenance without having to depressurize the tank in a safer and simpler way than with traditional multi-ported valves.
