Pressure Independent Control Valve
Features of Pressure Independent FlowControl Valve
Flow regulation and hydraulic balance are integrated;
The self-acting diaphragm differential pressure controller responds quickly to the change of flow rate;
Reduce the use of air conditioning system valves;
Improve the efficiency of water pump operation and save energy.
Pressure IndependentControl Valve Working Principle
PICVcontrol valvekeeps ∆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+P spring 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 PICV valve adjust the flow rate by adjusting the disc to change the Kv value.
Pressure Independent Control ValveInstallation and Commissioning
Specifications are determined according to the design flow rate of the air conditioning box and allowable pressure range of pressure independent balancing valve, and technical parameters are determined according to the requirements. For specific use, please consult Zeco Valve Group.
