Female Inlet × Female Outlet	Flared Angle Connector

Nickel-Plated Brass Body—Nickel-plated brass valves are more corrosion resistant than plain brass or bronze valves.

316 Stainless Steel Body—316 stainless steel valves have the best corrosion resistance.

Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

High-Flow Threaded Check Valves

To achieve the maximum possible flow, internal components are designed to reduce flow resistance. These valves open to allow flow in one direction and close when flow stops or reverses. A removable cap provides easy access to internal components for maintenance.

Check Valves with Yor-Lok Fittings

Two sleeves give these fittings extra gripping power. They bite into tubing as you tighten the nut to form a strong seal. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Valves open to allow flow in one direction and close when flow stops or reverses.

Clear-View Socket-Connect Check Valves for Harsh Chemicals

Visually inspect flow and debris accumulation through the transparent valve body. Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. Valves have a PVC body and a fluoroelastomer seal for excellent chemical resistance. They open to allow flow in one direction and close when flow stops or reverses. All have a removable cap that provides easy access to internal components for maintenance.
