Stainless Steel Wafer Butterfly Valve

ALIS Valves offers Stainless Steel Wafer Butterfly Valves designed for efficient flow isolation and control in industrial piping systems. These valves feature a stainless steel body and a rotating disc mounted on a central shaft that turns approximately 90 degrees to open or close the flow passage. The wafer-style body fits between two compatible pipeline flanges and is secured using suitable bolting arrangements, providing a compact and space-saving installation. Stainless steel construction offers corrosion resistance and durability in many industrial environments, while the disc, seat, shaft and sealing materials can be selected according to the process media and operating requirements. Depending on the application, these valves can be supplied with lever, gear-operated, pneumatic or electric actuation options to support manual or automated operation.

Stainless Steel Wafer Butterfly Valves are commonly used in water treatment, chemical processing, food and beverage production, pharmaceutical facilities, marine systems, HVAC installations and general industrial fluid handling. Depending on the stainless steel grade, seat material and valve design, they can handle compatible liquids and gases within their specified pressure and temperature limits. Important selection factors include valve size, flange compatibility, pressure rating, operating temperature, media composition, disc and seat materials, and required leakage performance. Buyers should also consider whether the valve is intended for isolation or throttling, as operating characteristics depend on the disc design and application. Correct installation between compatible flanges and proper selection of sealing materials are essential for reliable performance. Choosing the appropriate stainless steel wafer butterfly valve helps provide compact installation, corrosion resistance and dependable flow control in compatible industrial applications.
