working principle

The water pressure is used to control and regulate the pilot valve, so that the water pressure after the valve is lowered. Regardless of the inlet pressure fluctuation or the outlet flow rate change, the static pressure and dynamic pressure of the outlet are stabilized at the set value, and the outlet pressure can be adjusted within a certain range.

Characteristics

- Sensitive, precise and stable pressure control.
- Adjustable downstream pressure.
- Whether the flow changes or the upstream pressure changes
The downstream pressure is kept constant.
- Simple and reliable design, easy to install and maintain.

product manual

The hydraulic control valve is generally divided into two types: diaphragm type and piston type. The company adopts a diaphragm type with a caliber of Φ600mm or less, and a piston type with a caliber of Φ600mm or more.
The hydraulic control valve is a combination of a main valve and an external needle valve, a sound guide valve, etc., and is transformed into a remote control float valve, a fixed water level valve, a pressure reducing valve, and a slow closing check valve in accordance with the purpose, function and location. , flow control valves, pressure relief valves, electric control valves and pump control valves. The main valve is composed of main parts such as valve body, diaphragm, valve stem assembly and valve seat.
