Stainless Steel Sanitary Manual Butterfly Valve with Lever Handle

The working principle of the stainless steel sanitary welded manual butterfly valve with a lever handle is to manually control the position of the lever handle to drive the valve stem to rotate, thereby driving the valve plate to rotate around the central axis to achieve the switch or regulation of the fluid in the pipeline. The specific steps are: the operator manually pushes or pulls the lever handle, the lever drives the rotating mechanism inside the butterfly valve, and the valve plate gradually rotates from a position parallel to the pipeline to a vertical position, or gradually rotates back from a vertical position to a parallel position. When the valve plate is parallel to the pipeline, the pipeline is fully open and the fluid passes smoothly; when the valve plate is perpendicular to the pipeline, the valve is closed to prevent the flow of fluid.

Valve parts

• A special fluid distribution groove is designed inside the valve plate of the stainless steel sanitary welded manual butterfly valve with a lever handle to evenly distribute the fluid flowing through the valve and reduce local high-pressure areas.
• The valve body and valve plate surface of the stainless steel sanitary welded manual butterfly valve with a lever handle are treated with an antibacterial coating, which can effectively prevent the growth of bacteria and microorganisms and maintain the hygiene requirements of the pipeline system.
• The stainless steel sanitary welded manual butterfly valve with a lever handle adopts a seamless integrated sealing design, combined with an innovative self-adjusting elastic sealing ring, so that the sealing performance is not affected even in high-pressure or high-temperature environments.
• The valve stem of the stainless steel sanitary welded manual butterfly valve with a lever handle adopts a double sealing structure, with an internal and external sealing ring design inside and a special anti-leakage device outside.
• The valve body and pipeline connection part of the stainless steel sanitary welded manual butterfly valve with a lever handle adopt an integrated welding structure, which avoids the dead angle and leakage problems of traditional flange connections.
• The valve stem material of the stainless steel sanitary welded manual butterfly valve with a lever handle has been specially treated, has high-temperature oxidation resistance, and can withstand use in extreme high-temperature environments.

Stainless steel sanitary welded manual butterfly valve with pull rod handle is mainly used in industries with high requirements for hygiene standards. The following are several typical industries. Food processing: control liquid flow to ensure the hygiene and stability of the production line. Beverage production: adjust the flow, prevent pollution, and keep the beverage pipeline clean. Dairy products: Regulate milk flow to ensure that pipelines meet hygiene standards. Pharmaceutical industry: Control liquid delivery to meet high hygiene production requirements. Biopharmaceuticals: Control the flow of drug raw materials to maintain pollution-free delivery. Chemical industry: Used for liquid flow control to ensure the hygiene and safety of the pipeline system.
