Sanitary Stainless Steel Manual Welded rubber Diaphragm Valve
The Sanitary Stainless Steel Manual Welded Rubber Diaphragm Valve is a hygienic valve operated manually. Its welded rubber diaphragm provides leak-free sealing, corrosion resistance, and reliable flow control, making it suitable for food, pharmaceutical, and high-purity fluid systems requiring sanitary handling
Working Principles
The Sanitary Stainless Steel Manual Welded Rubber Diaphragm Valve operates by manually turning a handwheel or lever, which moves the diaphragm against the valve seat to control flow. The welded rubber diaphragm acts as a flexible barrier, sealing the valve body and preventing leaks while isolating the fluid from mechanical parts. Lifting the diaphragm opens the flow path, allowing liquids or gases to pass through smoothly. Its welded design ensures durability and corrosion resistance, while the manual operation allows precise, controlled regulation. This mechanism provides reliable, hygienic, and leak-free performance, making it ideal for food, pharmaceutical, and high-purity processing applications
