Application
The constant pressure adjust valve can guarantee a stable pressure at the inlet and outlet of the valve, so it is widely used in the rear of separator, heat exchanger, tank system and as overflow valve.
Work principle
The constant pressure adjust valve is operated remotely by compressed air, and the operation of the valve does not depend on any sensor in the pipeline that conveys the product, Only a pressure regulator for compressed air and a pressure gauge for monitoring the pressure on the product delivery line are required. A diaphragm / stem system can react quickly to any pressure change in the product delivered and change the stem position relative to maintain the preset pressure value. When the pressure of the delivery product increases, the valve opens. Conversely, the valve closes when the pressure of the delivery product is reduced.
Attention
The application of the chart description: mediumwater(20°C).
lt is recommended that the flow rate in pipes andvalves should not exceed 5 m/s.
