Product Overview
The INTERPULS CV20 (Part No. 1039092) is a precision-engineered hydraulic check valve designed to permit unidirectional flow while preventing reverse flow in industrial hydraulic and pneumatic circuits. Manufactured by INTERPULS, a recognized name in fluid control technology, this valve operates on a spring-loaded poppet or ball-seat principle, delivering reliable zero-leak sealing when the flow direction reverses. The CV20 is a direct-acting, non-piloted check valve suitable for in-line installation, providing essential backflow protection for pumps, actuators, and downstream system components. Its robust construction ensures stable cracking pressure and minimal pressure drop during forward flow, making it a critical safety and functional element in demanding process environments.
