Product Overview
The Parker LV3B6B is a precision-engineered check valve belonging to Parker Hannifin’s LV series of modular hydraulic valves. Operating on a direct-acting, spring-biased poppet principle, this valve permits free flow in one direction while providing zero-leak, bubble-tight shutoff in the reverse direction. As a modular (sandwich-style) component, the LV3B6B is designed to mount directly between a directional control valve and its subplate, eliminating the need for inline piping and reducing potential leak points in the circuit. It serves as a critical fluid control element in industrial hydraulic systems, preventing reverse flow, maintaining load holding, and protecting downstream components from pressure surges.
