DN50 Hastelloy SS304 Sanitary Vacuum Manual Pneumatic Welded Clamped Butterfly Valve

Application
This valve is in the form of an electric pneumatic regulating valve, used in automation control systems. The three-way regulating valve is designed to meet the needs of two different working conditions. It is used in a widely range of fields such as alcohol, pharmaceuticals, food, and water treatment.

Operational Principle
By providing a 4-20mA signal to control the valve opening percentage, the three-way regulating valve is designed to meet the needs of two different working conditions. It can be divided into two ways, three-way shunt and three-way confluence. A three-way diverter valve divides a fluid into two different flow rates. The three-way combined flow regulating valve is used to mix two fluids into one fluid, or to mix two fluids at different temperatures into the target temperature fluid.
