This cartridge-style, non-return valve is made with medical grade 316L stainless steel and a ceramic ball for improved compatibility with aggressive fluids and gases. This valve is designed specifically for installation into plastic housings, fittings, or soft tubing. The valve can be installed in either direction, providing forward or reverse flow capabilities. The valve features a high quality metal seat that provides low leakage, repeatable cracking pressure, and long life. The valve is 100% functionally tested to ensure performance.
