Product Overview
The NACHI PCR-3B-12A-P-9230C is a pilot operated check valve from NACHI-FUJIKOSI’s PCR series, engineered for precise load holding and controlled actuator locking in industrial hydraulic circuits. This modular-style valve permits free flow in one direction and blocks reverse flow until a pilot pressure signal is applied to the pilot port, at which point the internal poppet is mechanically unseated to allow controlled return flow. Manufactured to NACHI’s exacting tolerances, the PCR-3B-12A-P-9230C is designed for direct integration into modular valve stacks or manifold-mounted systems, providing reliable leak-free load holding for cylinders, motors, and other actuators in demanding hydraulic power units.
