The sanitary diaphragm valve is remotely operated by the driving device or manually operated by the handle. The driving device has three standards: normally closed type, normally open type and pneumatic type. The utility model has the advantages of simple structure, beautiful appearance, quick disassembly, flexible operation, small fluid resistance, safe and reliable use, etc. It is suitable for the control of water, gas, oil and corrosive medium in chemical, petroleum, metallurgy, water heating, food, medicine and other industries.

 

It can be remotely controlled by the driving device or manually operated by the handle. Sanitary diaphragm valve uses the valve stem to press the rubber film directly on the valve seat to cut off or connect the vacuum system.

 

Sanitary diaphragm valves are connected by looper flange connection, quick release flange connection and welding connection. Welding connection can be divided into welding type I connection (welding at both ends) and welding type II connection (welding at one end and inserting at the other end)

 

The reason of diaphragm valve structure design is especially suitable for ultra pure medium or heavily polluted, very viscous liquid, gas, corrosive or inert medium. When combined with control equipment, diaphragm valve can replace other traditional control systems, especially suitable for solid and easily polluted inert media
