Parker CK3 Check Valves

Parker’s CK-3 is a compact and lightweight check valve that features a threaded process connection that simplifies connections and reduces installation costs. The spring-loaded check valve requires a minimum 0.34 bar (5 psi) pressure drop to overcome the spring force and lift the valve seat, allowing the check valve to be mounted in any position. The valve opens wide for flow in the arrow direction on the body of the valve. When flow reversal occurs the CK-3 valve closes quickly and reliably.
