Pressure Control Cartridge Valve

The Direct Acting Relief Valve has the function of protect the hydraulic system form malfunctioning or breaking due to too high pressure level present into the circuit.

JRP10-01 is a pilot operated, spool type, pressure relief valve.When the set operating pressure is reached, the poppet spool opens and connects the protected line with the return line to the tank. By means of the adjusting mechanism, the poppet spool is pressed onto a seat which is screwed into the lower cartridge opening by a helical spring. The poppet spool is opened and closed hydraulically dampened. This makes the operation of this cartridge very stable. Thanks to the poppet/spool principle and the direct operation, these Pilot Operated Relief Valve are rapid acting and free of leakage oil. The reduced diameter of the seat produces a higher pressure drop and a lower flow throughput performance than Pilot Operated Relief Valve of the same size.

The Direct Acting Spool Type Cartridge Relief Valve is a pressure control valve that combines the characteristics of a direct-acting relief valve with an LS (Load Sensing) port. The direct-acting relief valve uses the principle of balancing the liquid pressure on the valve core with the spring force to control the opening and closing of the valve, thereby adjusting the system pressure; the LS port is used to introduce a load pressure signal, so that the relief valve can more accurately control the system pressure according to the load changes.

Directly Relief Valve is relieving thepressure by a poppet on its sealing seat. The poppet is pushed toopen and reliving the flow through T port when the pressure on Pport is higher than the spring pressing force. The spring force isavailable to adjust by regulating the head hexagon of the Directly Relief Valve with easy and flexible operation

The Directly with anti-cavitation Poppet Type Relief Valve combines in one compact insert cartridge the typical function of shock relief valve and anticavitation through the check valve.

The swing motor valve is mainly used to control the flow and pressure of the swing motor in the hydraulic system to ensure the stable operation of the system. When the flow in the hydraulic system exceeds the set value, the relief valve will automatically adjust the flow to keep it within the set range to avoid damage to the swing motor due to overload.

The Adjustable Relief and Anti Cavitation Valves combines in one compact insert cartridge the typical function of shock relief valve and anticavitation through the check valve.

DN10 Travel Motor Safety Valve is mainly used to control the flow and pressure of the travel motor in the hydraulic system to ensure the stable operation of the system. When the flow in the hydraulic system exceeds the set value, the relief valve will automatically adjust the flow to keep it within the set range to avoid damage to the travel motor due to overload.

Pilot Operated Cartridge Pressure Reducing Valve with internal pilot and internal spring chamber drain, intended as a secondary circuit pressure regulating device.
