By stacking a load-sensing valve and a pressure-limiting valve, the load-sensing valve operates when the system pressure is below the pressure-limiting valve’s set pressure; under this condition, the output flow rate is independent of the load. When the pressure rises to the pressure-limiting valve’s set pressure, the pump’s output flow reduces to meet only the leakage and actuator demand flow, thereby maintaining constant pressure.
TECHNICAL FEATURES
01. Capable of both pressure control and load-sensing control.
02. Excellent opening/closing characteristics ensure stable pump operating pressure and energy efficiency.
03. High-strength, high-elongation cast iron valve body, rated for peak pressure up to 45 MPa.
04. Imported alloy steel spring ensures long service life under sustained high-pressure operation.
