Adjustable Dynamic Flow Balancing Valve

Basic information

Adjustable dynamic flow balancingvalve can manually adjust the set flow rate in the pipeline, and also can automatically maintain the pressure difference before and after the valve unchanged, so as to achieve the controlled pipe road flow constant.

Features

1. 2. The self - acting diaphragm differential pressure controller responds quickly to the change of flow rate;3. reduce the use of air conditioning system valves;4. Improve the efficiency of the water pump operation and save energy.

Principle

This valve keeps P constant through the spring force. The pressure channel inside the valve body will adjust the pressure P1 and P2 at both ends of the structure, causing the upper and lower ends of the diaphragm respectively. The balance state P1=P2+Pspring will be maintained through the action of spring force，If P1 increases, the force acting on the lower part of the diaphragm increases correspondingly, and the diaphragm moves upward, reducing the pressure difference control structure space, and P2 increases accordingly to reach a new balance. And vice versa; And this valve adjusts the flow rate by adjusting the disc to change the Kv value.

Installation and Commissioning

Specifications are determined according to the design flow rate of the air conditioning box and allowable pressure range of the valve , and technical parameters are determined according to the requirements. For specific use, please consult ZhengFeng Valve Group.
