Clamp sanitary DN25 PTFE butterfly valves are available in manual or actuated types, with wafer or clamp connections. Common sizes center on DN25, using 304 or 316L stainless steel bodies, PTFE seats, hygienic design, corrosion resistance, and smooth, easy-to-clean internal surfaces.
The stainless steel clamp sanitary DN25 PTFE butterfly valve operates by rotating a circular disc mounted on a central shaft inside the valve body. When the handle or actuator turns the shaft, the disc rotates 90 degrees to open or close the flow path. In the open position, the disc aligns parallel to the flow, allowing smooth and low-resistance passage of fluid. When closing, the disc presses evenly against the PTFE seat, forming a tight and reliable seal. The clamp sanitary connection ensures quick installation and easy removal for cleaning, making the valve suitable for hygienic process applications.

● 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.
