Puhui brand ZTY47 self operated differential pressure control valve

ZTY47 (ZY17) series self operated differential pressure control valveIt is a hydraulic balancing valve with automatic constant pressure difference, applied in water systems such as centralized heating and air conditioning, which is conducive to the autonomous adjustment of various users and end devices of the controlled system. The self operated pressure difference control valve is particularly suitable for household metering heating systems and variable flow air conditioning systems. ZY47 series self operated differential pressure control valve is used to balance pipeline pressure.

Principle and structural characteristics of ZY47 series self operated differential pressure control valve

The ZY47 series self operated differential pressure control valve is a dual channel control valve that can change flow resistance and automatically regulate pressure. It is divided into two independent small chambers by a diaphragm, with one chamber connected to the return water pipeline. When installed on the return pipe. The channel is an automatic control valve actuator, whose force of action comes from the pressure difference between the water pressure P1 and P2 return water. The controller is a pressure difference comparator, and the pressure difference is based on the resistance of the selected controlled heating system. The spring reaction force of the return water is used to balance the pressure difference between the supply and return water. When some users adjust the room temperature, increase or decrease resistance in the heating control system, causing changes in the circulating flow until the diaphragm pressure of both parties is balanced, resulting in an internal automatic adjustment control system.
