Stainless Steel Sanitary Duckbill Welded Manual Butterfly Valve
The stainless steel sanitary duckbill welded manual butterfly valve is designed to provide an efficient and reliable fluid control solution under strict sanitary conditions. Its duckbill shape design can achieve better fluid sealing in the switch state, reduce the risk of dead corners and accumulated materials, and ensure that the fluid is always in a clean state. This valve is particularly suitable for scenarios that require fast switching and precise flow control, avoiding contamination of the fluid and reducing cleaning and maintenance costs. Through welding connection, it can ensure a more stable pipeline interface, adapt to high pressure or high flow application requirements, and ensure long-term stable operation of the system.
Working Principles
The working principle of the stainless steel sanitary duckbill welded manual butterfly valve is based on the rotation of the butterfly plate to control the switch and flow regulation of the fluid. First, the butterfly plate is driven to rotate in the valve seat by manually operating the valve stem. When the butterfly plate is in the closed position, the duckbill-shaped valve seat is in close contact with the butterfly plate, completely cutting off the fluid flow. When the butterfly plate rotates to the open position, the fluid can flow through the valve, and the design of the valve seat ensures the sealing.
The options of the stainless steel sanitary duckbill welded manual butterfly valve include:
Material selection: such as 304, 316 stainless steel, to meet different hygiene standards and corrosion resistance requirements.
Sealing material: such as EPDM, VITON, to meet the sealing requirements of different fluids.
Connection method: welding or quick-install connection method can be selected.
Operation method: manual operating lever, handwheel or gear drive.
Valve seat design: standard or duckbill design to meet different fluid flow requirements.

Features
● The stainless steel sanitary duckbill welded manual butterfly valve adopts a duckbill-shaped valve seat design, which can reduce friction and pressure loss when the fluid passes through.
● The stainless steel sanitary duckbill welded manual butterfly valve adopts a dead angle design, which reduces the area where the fluid stays in the valve and avoids the accumulation of impurities and dirt in the liquid.
● The sealing surface of the stainless steel sanitary duckbill welded manual butterfly valve plate and the valve seat adopts precision machining technology to ensure excellent sealing performance.
● The inner and outer surfaces of the stainless steel sanitary duckbill welded manual butterfly valve are coated with anti-corrosion coating, which effectively improves the durability of the valve in corrosive fluids.
● The structure of the stainless steel sanitary duckbill welded manual butterfly valve has been optimized and can withstand higher pressures, which is suitable for high-pressure pipeline systems.
● The operating mechanism of the stainless steel sanitary duckbill welded manual butterfly valve adopts a quick response design, which makes the switch action fast and stable.
Application
