operational principle

This constant pressure valve is designed for applications that require stable outlet or inlet pressure. A set of diaphragm and valve stem systems can quickly respond to any pressure changes in the conveyed product and correspondingly change the valve stem position to continue maintaining pre-set pressure values. Compressed air pressure is achieved through a pressure regulating valve and a pressure gauge. Suitable for stainless steel pipeline systems, in process pipelines, (inlet constant pressure) maintains a constant pressure at the inlet end of the valve and serves as an overflow valve. As the inlet is at a 90 degree angle to the bottom of the valve body, there is no residual liquid accumulation.
