1/4'' Stainless Steel Sanitary Manual Diaphragm Valves SP-4M AISI-316L
SP-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.
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.
Standards: DIN, 3A, SMS, ISO / IDF, BS / RJT, ASME / BPE.
The parts mainly include: a hand wheel, diaphragm and valve body which are assembled together with bolts and nuts. The body can be two ways or three ways.
End connections: butt-welded, sanitary clamp, or others upon request
Body type: T-type tee, U type tee, Mini type, tank bottom type, etc.
