Wai Hang Sanitary Manual Vacuum Straight Through Valve
Vacuum ball valve is a commonly used control valve that is easy to install and widely used in various vacuum systems. It can work normally under high vacuum conditions and can also be applied in low pressure systems, achieving the advantage of using both positive and negative pressures.
The valve is straight through and sealed by the spherical surface, so it can be used in vacuum or low pressure, and can be installed at any position to switch on or cut off the medium flow in the vacuum system pipe path. It is normally used in vacuum, dairy products, wine industry, bioengineering, food, pharmaceutical, beverage, cosmetics and chemical fields. Optional feedback signal device and electrical valve positioner.
There are various standard valve series can be supplied, they are the DIN,3A, SMS, ISO/IDF, BS/RJT, ASME/BPE standard etc. You can choose us with confidence, our products meet the standards of multiple regions, such as American Standards, Japanese Industrial Standard, Korean Standard, German Standard and Italian Standard. The constitute elements of ball valve always included: one handle, one ball body with transfixion cavity, valve body, valve central spindle and spindle shaft seal.
