Fisher relief valve features dual-pilot design

August 16, 2023 By    

The 2-in. MNPT 63EGLP pilot operated relief valve by Fisher provides overpressure protection for LP gas, NH3 and other pressurized fluid storage tanks. It features a dual-pilot design, which provides high accuracy relief and the ability to service one pilot while the other pilot controls the relief valve. Uninterrupted relief protection minimizes maintenance time and costs, according to the company. Two relief valves protect up to 1,574 sq. ft. of surface area or 30,000-gallon tanks, and three relief valves protect up to 2,581 sq. ft. of surface area or 30,000- to 45,000-gallon tanks. The valve provides a 40 percent increase in relief capacity and has a 20 percent weight reduction for easier installation. Other features include a stainless steel pilot construction, durable handle for ease of switching between idle and operating pilots, and a rain cap.
