Self regulating valve group

Overview of ZSYII Self Operated Control Valve Group - Dual Channel Pressure Reducing Valve:
Dual channel pressure reduction is only used in systems where the working conditions are particularly important and the system does not allow faults. Normally, one channel works while the other is closed for backup. As long as the flow rate is sufficient, it is not necessary to simultaneously open both channels of pressure reduction to avoid valve opening being too small, which may cause vibration and noise and affect the service life of the valve.
