working principle

The pilot valve is controlled by the water force, so that the main valve automatically discharges part of the water to stabilize the set pressure of the pipe before the valve. When the pressure returns below the set pressure, the main valve is automatically closed, and the pressure relief and holding pressure of the valve are within a certain range. You can adjust.

Characteristics

- When the water level reaches the preset water level, the valve will automatically close and the valve will automatically open the water when the water level drops.
- Simple maintenance, flexible and durable, high liquid level control accuracy, water level is not affected by water pressure, and the water is closed tightly and not leaking. The float ball can be separated from the main valve.
