2、 Core Technical Parameters (Comparison of Three Models)

3、 Structure and Working Principle

• structurePilot operated superposition valve, consisting ofMain valve+pilot valve+pressure regulating spring+control oil portform;D-type is leakage， The L port needs to be returned to the fuel tank separately.

• principle：

1. The primary pressure (P) is reduced to the secondary pressure (A) through throttling of the main valve.

2. The secondary pressure feedback is sent to the pilot valve, which automatically adjusts the opening of the main valve,Stable export pressure.

3. Control the introduction of oil from port B,Remote pressure regulation/unloadingThe leakage type L port returns oil separately to reduce the impact of back pressure.

5. 4、 Performance characteristics

7. Stacked designWithout the need for a base plate, it can be directly stacked and installed,Save space, shorten oil lines, and reduce leakage points.

8. Dual pressure coverage：

1. Type C (FC)：8～20 MPa， Adapt to high-voltage systems;

2. No C (F)：0.6～8 MPa， Suitable for low-voltage precision circuits.

9. Leakage optional (D)：D-type leakageDrain the oil independently and return it to the oil tank,Higher voltage stabilization accuracy (≤± 0.1 MPa)Suitable for high-precision control.

10. P-type controlA enters the oil, B controls, supportsRemote pressure regulation/multi-stage pressure controlAdapt to complex systems.

11. Cast iron valve bodyPressure resistance of 25 MPa, vibration resistance, low noise, suitable for long-term industrial operation.
