ZYC self-operated differential pressure control valve

Nominal pressure:PN1.0~2.5MPa
Nominal diameter:DN50~200mm

ZYC self-operated differential pressure control valve is a valve that uses the pressure change of the medium itself for self-control to keep the differential pressure of the medium flowing through the controlled system unchanged. It is suitable for differential pressure control of dual pipe heating system. Ensure that the pressure difference of the system is basically unchanged, reduce noise, balance resistance, and eliminate the imbalance of heat supply network and hydraulic.
