ZYC Self standing differential pressure control valveDetailed product description：

ZYC differential pressure control valve is a valve that uses the pressure changes of the medium itself for self-control to maintain the constant pressure difference of the medium flowing through the controlled system. ZYC self-supporting differential pressure control valve is suitable for differential pressure control in heating systems using dual pipe systems. Ensure that the system pressure difference remains basically unchanged, reduce noise, balance resistance, and eliminate thermal and hydraulic imbalances.
