Application
AV-4M series is a manual type sanitary diaphragm valve, which is widely used in food, beverage, dairy, brewing, pharmaceutical industries, etc. It is excellent for flow control as well as for open/close duties.
Materials
Steel parts: stainless steel AISI 316L / 304 (forged)
Diaphragm: EPDM + PTFE
The seal materials comply with FDA177.2600 standard. Using proprietary technology, the diaphragm uses a combination of EPDM and PTFE, which is secured using SS bolts. The sealing part where contact with the medium is of PTFE material, it has good cold resistance -13°F (-25°C), excellent heat-resistance 482°F (+250°C), tolerance to most chemicals, and excellent abrasion resistance to medium flow.
Standard Design
