ZDR6 Superimposed Pressure Reducing Valve
The ZDR6 superimposed pressure reducing valve is a key component used to regulate and control pressure in hydraulic systems. The following is a detailed introduction from its structural characteristics, working principles, technical parameters, application advantages, etc.:
1. Structural characteristics
Superimposed design: The ZDR6 series pressure reducing valve adopts a superimposed structure, which can be directly installed on the hydraulic valve plate and combined with directional valves, flow valves, etc. to form a compact hydraulic control system.
Tee structure: has three oil ports (P, A, T), which can realize pressure adjustment and oil circuit switching functions.
Direct-acting control: Directly feel the inlet pressure through the valve core, achieving rapid response and precise control.
Optional one-way valve: Some models are equipped with one-way valves to prevent oil backflow and protect the system from safety.
2. Working principle
Initial state: In the rest position, the valve core is in the open state, and the oil can flow freely from port P to port A.
Pressure adjustment: When the pressure of port A exceeds the set value, the valve core moves under the action of spring force, reducing the flow area and reducing the pressure of port A.
Pressure stability: The stable output of port A pressure is achieved by balancing the spring preload force and port A pressure.
Overload protection: If the pressure at port A continues to rise, the valve core is completely closed, and the oil flows back to the oil tank through port T to prevent the system from being overloaded.
