Structural features of ZYC self- operating pressure difference control valve :

The body of ZYC self-operating pressure difference control valve is a combination of a dual-channel automatic regulating valve that can change the flow resistance and a controller separated by a diaphragm into two independent chambers. It is installed on the return water pipe during use. The channel automatic regulating valve is an actuator, and its motive force comes from the pressure difference between the water supply pressure P1 and the return water pressure P2. The controller is a pressure difference comparator. The pressure difference value is selected according to the resistance of the controlled heating system. The spring reaction force in the return water side is used to balance the pressure difference between the water supply and the water. When some users of the controlled heating system adjust the room temperature and the resistance increases or decreases, it will cause the circulation flow to change until the pressure on both sides of the diaphragm is balanced, so that the internal control system will automatically adjust .

Installation instructions of ZYC self- operating differential pressure control valve :

Select the diameter as small as possible, and consider reducing the diameter when the flow is too low. The control valve pilot pipe is connected with 1/2 pipe thread,

The pressure guiding pipe is 1.5m in length and is connected to the water supply pipe. This valve is divided into two types: constant pressure differential type and adjustable differential pressure type. Nominal pressure: 1.6MPA, medium temperature 0-120 ° C
