The newly designed Packless Valve, Generation II, features a forged brass, cored body for maximum strength and rigidity, and a corrosion-resistant stainless steel spring for long life, says the company. Large-diameter diaphragms of dissimilar metals permit greater lift, aid flow, and ensure longer life, the company says. A raised seat reduces the possibility of foreign matter accumulating on the valve seat, says the manufacturer. The nylon seat disc assembly is suitable for refrigerants and other hazardous or expensive industrial fluids.
