This is a Pneumatic Diaphragm Stainless Steel Control Valve, an automatic flow control valve powered by compressed air. It mainly consists of a pneumatic diaphragm actuator, valve positioner, filter regulator, and stainless steel valve body:It receives control signals (e.g., 4-20mA) via the positioner, adjusts the air pressure in the actuator to drive the valve core to lift, and changes the flow area to precisely control fluid flow; the handwheel enables on-site manual adjustment, suitable for emergency conditions such as power/gas failure.
Made of stainless steel, it has excellent corrosion resistance and is suitable for working conditions such as water, steam, and weakly corrosive chemical media. It is widely used in automatic process systems of food and pharmaceutical, petrochemical, environmental protection industries, enabling precise and stable regulation of fluids.
