Product Overview
The PARKER 491514C2 is a high-performance D4B series solenoid-operated directional control valve engineered for precise hydraulic circuit switching in demanding industrial environments. Manufactured by Parker Hannifin, a global leader in motion and control technologies, this valve utilizes a robust spool-and-sleeve design actuated by a wet-armature solenoid to direct hydraulic flow with exceptional repeatability. The D4B platform is renowned for its high flow capacity, low pressure drop, and rapid response characteristics, making it a critical component for controlling actuator direction, speed, and holding functions in complex hydraulic power units and manifold systems.
