Fisher™ Type 63EGLP Relief Valve
Type 63EGLP relief valve provides significant overpressure protection for LP-Gas storage tanks.
Compared to the Multi-Port Manifold Relief Valves, they have 40% more relief capacity and lower installation and maintenance cost. One relief valve will protect over 3,000 sq. ft of surface area by providing relief capacities exceeding 38,790 SCFM. The unique dual-pilot design allows for the removal of pilot for set point verification and maintenance without having to depressurize tank.
