Working Principle
Series of constant pressure control valves are operated by compressed air, the operation of the series valve does not need to rely on any sensor in the pipeline only a pressure regulating device and product delivery pipeline for the pressure monitoring system is required A diaphragm valve stem system can quickly respond and change the valve stem position relative to the position of the valve stem so as to maintain the preset pressure value. When the pressure of the delivery product rises, the valve will open, and vice versa, the pressure of the product is reduced the valve will be closed.
