Butterfly Tanker Valve
What is a Butterfly Tanker Valve?
A Dairy Butterfly Tanker Valve is a hygienic, quarter-turn valve designed specifically for use in milk tankers, transport vessels, and other mobile food-grade fluid systems. It features a central rotating disc and high-quality sealing to ensure smooth, leak-free flow control and quick shut-off during transfer operations.
Asaid Steel Industries is a trusted supplier of Dairy Butterfly Tanker Valves, delivering precision-engineered valves in SS 304 and SS 316L with hygienic design, CIP/SIP compatibility, and long service life.
