.A11V130LRDU2 THE hydraulic pump head valve

The hydraulic pump head valve, as a crucial component of the externally controlled hydraulic pump motor, plays a vital role in the hydraulic system. The externally controlled hydraulic pump motor is a device that adjusts the output flow rate and pressure of the hydraulic pump through external signals or control mechanisms. By utilizing valves such as throttle valves, the flow rate of hydraulic oil can be precisely controlled, thereby regulating the output speed and torque of the hydraulic pump motor. This aids in meeting the performance requirements of the hydraulic pump motor under various operating conditions. Valves like relief valves protect the hydraulic pump motor from excessive pressure. When the system pressure exceeds the preset value, these valves automatically open to release the excess pressure, thereby preventing damage to the hydraulic pump motor. By controlling the opening and closing of directional control valves, the flow direction of the hydraulic oil can be changed, thereby regulating the rotation direction of the hydraulic pump motor.
