Stainless Steel Industrial Sanitary Manual Duckbill Butterfly Valve

The working principle of the stainless steel sanitary duckbill welded manual butterfly valve is based on the rotation of the butterfly plate in the valve body to control the flow of the fluid. The valve rotates the valve stem manually to gradually rotate the butterfly plate from the opening of the pipeline to form a fluid channel or completely close the pipeline. When the operating handwheel rotates, the valve stem drives the butterfly plate to rotate around its central axis. The angle adjustment of the butterfly plate determines the size of the fluid channel, thereby achieving flow regulation or closure. The structure of the stainless steel sanitary duckbill welded manual butterfly valve is simple, easy to clean and maintain, and meets the needs of frequent disinfection.

The options of the stainless steel sanitary duckbill welded manual butterfly valve include:

Material: 304 stainless steel, 316 stainless steel, etc.

Sealing material: silicone, fluororubber, EPDM, etc.

Drive mode: manual, pneumatic, electric.

Connection method: welding, clamp, threaded connection.

Butterfly plate design: full channel type, half channel type, one-way flow type, etc.

Valve parts

• The stainless steel sanitary duckbill welded manual butterfly valve reduces turbulence and makes the flow smoother when the fluid flows through the valve body.
• The stainless steel sanitary duckbill welded manual butterfly valve adopts a precision stem and butterfly plate connection system, which can achieve more precise angle adjustment.
• The stainless steel sanitary duckbill welded manual butterfly valve seal ring design has adaptive ability, which can automatically adjust the sealing effect according to the temperature and pressure fluctuations during use.
• The edge of the stainless steel sanitary duckbill welded manual butterfly valve butterfly plate has been optimized to reduce the area of contact with the fluid, which helps to reduce friction and the risk of fluid contamination.
• The stainless steel sanitary duckbill welded manual butterfly valve stem system has an adjustable preload function, which can be adjusted manually.
• The stainless steel sanitary duckbill welded manual butterfly valve has a streamlined shape to reduce the resistance of the fluid flow, thereby reducing energy consumption and flow loss.
