The fluid path and diaphragm positioning and seating enable this valve type to be used for throttling or simple stop operations. They are generally tolerant of particulate matter entrained in the media. Selecting body and diaphragm materials that are compatible with the media are primary elements of achieving a successful application. The diaphragm is a wearing part and should be inspected periodically and replaced when necessary.
Diaphragm valves for industrial use are available in a range of materials and sizes to accommodate light through heavy duty applications.
- Suitable for inert and corrosive liquid and gaseous media when proper valve body and diaphragm materials are selected
- Bonnet and valve bodies available in metal or plastic construction
- Insensitive to particulate media
- Valve body and diaphragm available in various materials and designs
- Compact design
- Automation via pneumatic or electric means
