The self-operated differential pressure control valve is a valve that uses the pressure change of the medium itself to control itself and keep the pressure difference of the medium flowing through the controlled system unchanged. It is suitable for heating mode. The pressure difference control of the double-pipe system ensures that the system remains basically unchanged, reduces noise, balances resistance, and eliminates heat network and hydraulic imbalance. The self-operated flow control valve is used in water systems that require flow control, especially for flow control of non-corrosive liquid media such as heating and air conditioning.
