Long life and durability.
DPCVWorking Principle
P1 is the pressure of water supply, P2 is the pressure of backwater in the valve and P3 is the pressure of backwater outside the gate valve. When P1-P3 increases, the induction diaphragm moves the disc upward, reducing the flow area and increasing P2-P3, thereby maintaining P1-P2 constant, i.e. the pressure difference on the control system remains unchanged. Conversely, if P1-P3 decreases, the disc will move down, P2-P3 will decrease, and P1-P2 will remain unchanged. If P1-P3 remains unchanged, and the resistance within the controlled system changes, such as P1-P2 increases, the disc opens slightly, so that P2 returns to its original value, that is, P1-P2 remains unchanged. Therefore, this valve can adjust the pressure changes in the system outside the controlled system.
Differential Pressure Control Valve Installation and Commissioning
This high pressure valve Chinais the backwater installation method. The control pipe is connected with the connection of the water supply pipe. External type: connected with the supply pipe at the front end of the controlled system and connected with the preset control interface of thecopper guide valveat the end; The differential control valveandbalancing valve pressure dropare used together. The balance valve is responsible for flow measurement, shutoff, and connection of the pressure pipe. For specific use, please consult ZECO Valve Group.
