Spool Directional Valve (with all drawings and dimensions) · 模型 127541
A spool directional valve is a hydraulic or pneumatic device that starts, stops, and changes the direction of fluid flow inside a system using a sliding cylindrical shaft called a spool. How It Works The Spool: A solid metal cylinder with ridges (glands) and grooves (undercuts) that moves back and forth inside a matching bore in the valve housing. Ports: Openings in the valve body that connect to the pump, fluid reservoir, or actuators (like hydraulic cylinders and motors).Shifting: Moving the spool blocks or opens specific paths between the ports, routing pressurized fluid to make an actuator move forward, backward, or stop. Common Actuation Methods Manual : Pushed or pulled by a mechanical hand lever or button. Solenoid: Moved instantly using an electromagnetic coil controlled by electrical signals. Spring Return: Automatically pushes the spool back to a default, neutral starting position when power or manual force stops. Main Spool Center Configurations Tandem-Center: Directs pump flow straight back to the tank while blocking actuator ports in neutral; ideal for standard mobile and industrial machines. Closed-Center: Blocks all ports in the neutral position, keeping fluid trapped and holding the actuator rigidly in place. Open-Center: Connects all working ports to the tank in neutral, allowing the fluid to flow freely with minimal pump resistance. If you'd like, let me know: Is this for a hydraulic or pneumatic setup? What actuation method do you need (solenoid, manual lever)?What is the target application or machine ?I can help you find the right valve configuration or specifications.
