working principle

The use of water action and adjustment of the differential pressure balance pilot valve, automatic control of the valve opening, commonly used in the central air conditioning diversion, water supply, return water balance the pressure difference between the valves, so that the medium in the pipeline maintains a constant pressure difference.

Characteristics

- Precise differential pressure control.
- Increase system utilization. - Reduce noise and reduce equipment damage caused by differential pressure.
- Reduce noise and reduce equipment damage caused by differential pressure.
- The pressure difference between any two points in the control line is at the set value and is not affected by pressure changes and flow in the line.

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.
