    Welcome to explore our main valve and relief valve catalog

    Whether for excavators, engines, telescopic boom lifts, transport refrigeration units, tractors, backhoe loaders, or bulldozers, we offer valves perfectly suited to your needs.

     

    Our valve selection includes, but is not limited to:

    1. Counterbalance valve: Balances loads in hydraulic systems, preventing sudden drops due to gravity or external factors.
    2. Position 4 way proportional valve: Controls actuator position and speed with precision.
    3. Air control valve: Manages airflow, commonly used in air suspension systems.
    4. Balanced piston relief valve: Regulates hydraulic system pressure, ensuring safe operation.
    5. Cartridge non-return valve: Prevents fluid backflow, ensuring unidirectional flow.
    6. Check valve: Controls fluid flow in one direction, preventing reverse flow.
    7. Directional valve: Determines fluid flow direction in hydraulic systems, directing fluid to different actuators or circuits.
    8. Flow control pump valve: Regulates pump flow in hydraulic systems, adjusting flow and pressure.
    9. Hydraulic relief valve: Controls system pressure to maintain safe operating conditions.
    10. Main relief valve: Primary relief valve in hydraulic systems, controlling overall system pressure.

     

    Our valves cater to a range of major equipment brands, including John Deere, Hitachi, Komatsu, Genie, Caterpillar, Thermo King, Yanmar, JCB, Hyundai, Kobelco, Perkins, Doosan, Daewoo, and more. Whatever your equipment brand, we provide high-quality, reliable valves to ensure smooth operations.

     

    What is a main valve?

    The main valve typically serves as a primary control valve for the entire hydraulic system, regulating fluid flow in and out and directing it as needed for specific functions.

     

    What is a relief valve?

    The relief valve controls the hydraulic system pressure not to exceed the specified value and does not have an electromagnetic coil. When the pressure exceeds the set value, the safety valve opens, releasing excess fluid to protect the system from overload damage.

     

    What is a main relief valve?

    A main relief valve is a primary relief valve in hydraulic systems, controlling pressure across the entire system. Typically installed in the main hydraulic circuit, it ensures the system operates within safe pressure limits.
