stainless steel pneumatic diaphragm valve
- suitable for inert and corrosive liquid and gaseous media
- valve body and diaphragm are available in a variety of materials
- insensitive to granular media
- support cip/sip
- some model can be pasteurized.
- the surface is electro-polished until roughness reaches 0.25um
