Shanghai valve self operated pressure control valve ZYC-16DN100 Seiko HOLLEY Carlsberg Guanlong

ZYC self operated differential pressure control valve is a kind of energy saving product which keeps the pressure difference of the controlled system through the pressure change of the medium itself. It is suitable for the pressure difference control of the double pipe system in the heating mode, which ensures the pressure difference of the system basically unchanged, reduces the noise, balances the resistance, and eliminates the hydraulic maladjustment of the heat supply network.

Overview of self operated differential pressure control valve:
ZYC self operated differential pressure control valve is a kind of energy saving product which keeps the pressure difference of the controlled system through the pressure change of the medium itself. It is suitable for the pressure difference control of the double pipe system in the heating mode, which ensures the pressure difference of the system basically unchanged, reduces the noise, balances the resistance, and eliminates the hydraulic maladjustment of the heat supply network.

ZyCWorking principle:
The ZYC self operated differential pressure control valve installed on the return water pipe is taken as an example to illustrate the working principle. When the water supply pressure P1 increases or decreases, the signal is transmitted through the connecting pipe, such as the upper cavity of the diaphragm, which drives the spool to move down, so that the flow area of the valve seat is reduced or increased. P2-P3 also increases or decreases, until the P1-P2 value remained constant. When the return pressure P3 increases or decreases the moment with the seat velocity to reduce or increase the flow of exports, the film pressure at the moment of P2 also increased or decreased, which drives the valve core to move up or down, know the diaphragm force balance, P2 recovery value, P1-P2 protection value is constant, thereby ensure that the controlled system between supply and return water the pressure difference basically unchanged.
