This is a Pneumatic Diaphragm Three-Way Control Valve, a multi-path flow control valve powered by compressed air. It mainly consists of a pneumatic diaphragm actuator, valve positioner, filter regulator, and three-way valve body (marked DN50 indicates nominal diameter):It receives control signals (e.g., 4-20mA) via the positioner, adjusts the actuator air pressure to drive the valve core to rotate/lift, realizing functions such as fluid confluence (two media merging into one path), diversion (one medium splitting into two paths), or commutation, while precisely controlling flow rate. The handwheel can be used for on-site manual adjustment, suitable for emergency working conditions.
Made of high-temperature/corrosion resistant material, it is suitable for water, steam, chemical media, etc. It is widely used in fluid distribution and mixing processes in petrochemical, pharmaceutical, water treatment industries, improving the medium scheduling flexibility of pipeline systems.
