SMS Union Butterfly Valve

ALIS Valves offers SMS Union Butterfly Valves designed for efficient flow isolation and control in hygienic and sanitary process piping systems. These valves feature a rotating disc mounted on a central shaft that turns approximately 90 degrees to open or close the flow passage. The SMS union end connection provides a detachable connection using compatible union fittings, allowing convenient installation, dismantling and maintenance. Depending on the design, the valve may feature a stainless steel body, a corrosion-resistant disc, suitable seat and seal materials, and smooth product-contact surfaces to support hygienic processing requirements. The compact construction and removable union connection make these valves suitable for installations where regular cleaning, inspection and equipment servicing are important.

SMS Union Butterfly Valves are commonly used in food and beverage processing, dairy production, pharmaceutical manufacturing, cosmetics and other hygienic fluid handling applications. Depending on the valve construction and material selection, they can handle compatible liquids and process media within their specified pressure and temperature limits. Important selection factors include valve size, SMS union connection standard, stainless steel grade, disc and seat materials, operating pressure, temperature range and media compatibility. Buyers should also verify gasket compatibility, required leakage performance and suitability for clean-in-place (CIP) procedures where applicable. Correct alignment and tightening of the union connection are essential for a secure, leak-resistant installation. Selecting the appropriate SMS union butterfly valve helps provide convenient maintenance, hygienic flow control and dependable performance in compatible industrial processing systems.
