STAINLESS STEEL Aluminum Demco Pneumatic Drive Gearbox Butterfly Valve
The butterfly valve is available in normally open and normally closed types, with pressure ratings of PN10–PN16, grooved connection, valve body material of 304/316, reliable sealing, fast response, and is suitable for automatic control pipelines.
Working Principles
The butterfly valve, made of stainless steel and aluminum alloy, uses a pneumatic actuator to control the rotation of the valve stem, thus opening and closing pipelines. Compressed air enters the cylinder, pushing the piston, and the torque is amplified by the gearbox, causing the butterfly plate to rotate rapidly to open or close. When closed, the butterfly plate presses against the valve seat to form a seal, preventing media leakage. The eccentric or standard butterfly plate design reduces friction and wear, extending service life. This valve features fast response, allows for remote automatic control, and is suitable for water, gas, steam, and chemical liquid pipelines, especially suitable for large-diameter industrial systems with frequent opening and closing conditions.

Features
● The stainless steel sanitary welded duckbill manual butterfly valve adopts a duckbill sealing structure to effectively prevent fluid leakage and ensure the sealing of the system.
● The stainless steel sanitary welded duckbill manual butterfly valve adopts welding connection, which reduces the leakage problem that may occur at the threaded connection.
● The stainless steel sanitary welded duckbill manual butterfly valve body, valve disc and sealing components are all made of 304 or 316L stainless steel, which has strong corrosion resistance.
● The stainless steel sanitary welded duckbill manual butterfly valve adopts a manual butterfly valve design, which is easy to operate and suitable for simple adjustment and control of fluid flow.
● The flow channel in the body of the stainless steel sanitary welded duckbill manual butterfly valve is streamlined, which reduces fluid resistance and improves flow efficiency.
● The stainless steel sanitary welded duckbill manual butterfly valve has a compact design and occupies a small space, which is suitable for installation in narrow or limited spaces.
Application
The industries where stainless steel sanitary welded duckbill manual butterfly valves are applied are mainly the following: Food industry: used to control the flow and flow of liquids during food processing. Beverage industry: control the flow of fluids in beverage production lines to ensure hygiene requirements. Pharmaceutical industry: regulate the flow of fluids in drug production to ensure clean standards. Dairy industry: ensure the control and sealing of fluids in dairy production. Chemical industry: used for switch control of chemical fluids to prevent leakage and contamination. Water treatment industry: Accurately adjust the flow rate during water treatment to ensure treatment effect.
