product description
Diaphragm valve is a special form of cut-off valve with compact structure and roof The flow path is simple and has good self-cleaning properties. It can be used with single diaphragm (EPDM) and double diaphragm (EPDM+PTFE). The valve body is made of precision casting stainless steel material , and the inner wall is polished without dead corners. The valve is acid and alkali resistant, has no leakage, is not contaminated with bacteria, is easy to sterilize, and is easy to maintain.
· Application places ·
is widely used in automated production process control fields such as medicine, food, dairy industry, biomedicine fermentation that require sterile hygienic conditions, and is the preferred product in the biochemical pharmaceutical industry.
