Hydraulic Control Valve

Hydraulic Control Valve – Multi-Spool Type

A 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.
