ZYC type self operated pressure balance valve is an energy-saving product that utilizes the pressure change of the medium itself to self control and maintain the constant pressure difference of the medium flowing through the controlled system. Suitable for the pressure difference control of a dual pipe system in heating, ensuring that the pressure difference of the system remains basically unchanged, reducing noise, balancing resistance, and eliminating hydraulic imbalance in the heating network.

Installation of pressure balance valve control pressure difference:

The ZYC type self operated differential pressure control valve installed on the return water pipeline is used as an example to illustrate its working principle. When the water supply pressure P1 increases or decreases, the signal is transmitted from the connecting pipe to the upper chamber of the diaphragm, driving the valve core to move down or up, reducing or increasing the flow area of the valve seat. P2-P3 also increases or decreases until P1-P2 remains constant. When the return water pressure P3 increases or decreases, the flow rate from the valve seat to the outlet decreases or increases, and the pressure P2 under the diaphragm also increases or decreases at this moment, driving the valve core to move up or down until the force on the diaphragm is rebalanced, P2 returns to its original value, and P1-P2 protects the original value to be constant, thus ensuring that the pressure difference between the supply and return water of the controlled system remains basically unchanged.

Control pressure difference range of self operated pressure balance valve:

Constant pressure difference type: 0.03MPa, accuracy ± 10%
