Safety valves for air, gas, and cryogenic systems. The unique three-piece disc assembly [with Teflon® seat/seal] delivers exceptional “no leakage” performance over the entire pressure/temperature operating range. The adjustment ring enables precise opening and closing differential pressure adjustment. Heavy-duty construction for long life. Install a pivot between the disc and the spring to correct any misalignment and compensate for the lateral thrust of the spring.
