PRODUCT OVERVIEW
Sanitary manual diaphragm valve is a common pipeline control valve. It has the characteristics of simple structure, beautiful appearance, fast disassembly and assembly, flexible operation and low fluid resistance. It can be operated manually through the handle. All steel parts are made of acid resistant stainless steel, and the seals are made of food silicone rubber or polytetrafluoroethylene, which meets the food hygiene specifications. The valve uses the valve stem to press the rubber film directly on the valve seat to stop or connect the vacuum system. It is widely used in many industries such as food, wine making, beverage, dairy products, fine chemicals, pharmacy and bioengineering.
PRODUCT ADVANTAGES
1. Due to the structural design of diaphragm valve itself, it is especially suitable for ultra pure medium or highly polluted and viscous liquid, gas, corrosive or inert medium.
2. When combined with control equipment, diaphragm valve can replace other traditional control systems, especially for solid and easily polluted inert media.
