SMS/DIN/3A/Rjt Munual Hygienic Sanitary Butterfly Valve

QILI is your trusted supplier of SS304 and SS316L Clamp/Weld/Thread Four-Position Butterfly Valves designed for use in the Bakery, Beverage, Cosmetic, Dairy, Food, and Pharmaceutical Industries. Our valves are available in sizes from 1" to 6", featuring four positions that allow for gradual opening, reducing stress on the valve seat compared to traditional open/close mechanisms. This design offers more control over flow rates, making it ideal for precision applications. Each valve comes with a clamp, weld, or thread end, making it easy to assemble and disassemble during cleaning or in tight spaces. The black or blue ball attached to the handle ensures visibility and ease of operation. The handle can be installed on either side, offering flexibility in installation locations. All QILI valves are 100% hydraulically pressure tested and inspected before shipping. They feature standard silicone seats and a sanitary finish of 25 Ra or better. Each valve is capped and bagged to protect the ends, and each unit is permanently etched with size, alloy, and heat number for full traceability. We also offer OEM services and custom designs to meet specific customer requirements.
