Used to prevent back-flow of product in the line. Our spring-loaded check valves features a Teflon-guided disc & stem. The Smooth Mover! Our check valves are constructed entirely of 316 stainless steel for highest corrosion resistance. The disc of the check valves are fitted with a EPDM* "O" ring, making the valves leak proof and compatible with most products. No tools needed. A twist of the wingnut opens the standard heavy-duty clamp: the check valves are dismantled, ready for sterilization. Check valves are self-draining when installed vertically and meets all 3A standards. The teflon-guided stem, fitted with a light stainless steel spring, assures positive closure and easy action.

Manufacturer

Pressures to 20,000 psi MAXIMATOR o-ring check valves provide high quality directional flow control and tight shutoff for liquids and gases. All check valves are supplied with glands and collars. These check valves are not to be used as a relief device. Pressures to 20,000 psi MAXIMATOR ball check valves prevent reverse flow where bubble tight shutoff is not mandatory. These check valves are designed with a ball cradled floating poppet to assure positive inline seating. This poppet design allows full flow around the ball to minimize pressure drop.
