Product Overview
The Eaton CV3-8-P-0-010 (02-171257) is a precision-engineered screw-in cartridge check valve designed for direct integration into hydraulic manifolds and integrated circuit blocks. As part of Eaton’s CV3 series, this cartridge-style valve provides reliable one-way flow control, permitting free flow in one direction while positively blocking reverse flow to protect system components and maintain circuit integrity. The “8” size designation corresponds to an 8-size cavity (nominally 3/4″ interface), and the “P” porting configuration denotes a specific port arrangement for manifold installation. With a zero-leakage poppet seating design and a nominal cracking pressure of approximately 0.3 bar (010 designation), this valve is ideally suited for load-holding, anti-siphon, and directional blocking functions in demanding industrial hydraulic circuits. Its compact cartridge format allows high-density manifold packaging, reducing external piping, potential leak points, and overall system footprint.
