Hydraulic Control Valve – Multi-Spool Type Hydraulic control valve is a critical component used in hydraulic systems to control the direction, pressure, and flow rate of hydraulic fluid. The specific valve shown is a multi-spool directional control valve, typically used in mobile and industrial hydraulic equipment. Key Features: Multi-Spool Design: Allows independent control of multiple hydraulic functions (e.g., cylinders, motors). Cast Iron Construction: Ensures durability, high pressure resistance, and a long service life. Manual/Lever Operation: Operated via levers, which direct hydraulic fluid through different channels based on the spool position. Pressure Relief Valves: Built-in safety features to protect the system from overpressure. Multiple Ports: Clearly marked inlet (P), outlet (T), and work ports (A/B) for easy installation and maintenance. Compact Form Factor: Space-saving design, ideal for mounting in confined areas. Application: Widely used in agricultural machinery, construction equipment, loaders, cranes, and other mobile hydraulic applications. Functionality: Each spool within the valve corresponds to a hydraulic actuator. When a spool is moved, it opens specific internal channels, allowing hydraulic fluid to flow from the pump to a particular actuator, while returning fluid from other actuators back to the tank.
