It is manufactured from 316L stainless steel with an interior mirror-polished finish of Ra ≤ 0.2 µm.\u003c\/p\u003e\n\u003cp\u003eThis ensures zero external leaks and maximum cleanliness in each cycle. Therefore, it is the preferred choice in the pharmaceutical, food, and biotechnology industries.\u003c\/p\u003e\n\u003cp\u003eUnlike conventional valves, the diaphragm acts as a hermetic seal between the fluid and the mechanism. This eliminates dynamic packing and, likewise, reduces the risk of product contamination.\u003c\/p\u003e\n\u003cp\u003eThe 3A clamp connection also allows for quick disassembly for maintenance or inspection without special tools.\u003c\/p\u003e\n\u003ch3\u003eWhy choose Cematic's hygienic diaphragm valve\u003c\/h3\u003e\n\u003cp\u003eFirstly, its mirror-polished finish of Ra ≤ 0.2 µm prevents residue accumulation. Consequently, CIP and SIP processes are more efficient than with valves with an Ra ≤ 0.8 µm finish.\u003c\/p\u003e\n\u003cp\u003eOn the other hand, 316L stainless steel offers greater resistance to chlorides and corrosive agents than SS304. It is also the preferred material in demanding CIP protocols. Therefore, it is the preferred material in environments with demanding cleaning protocols.\u003c\/p\u003e\n\u003cp\u003eIts manual operation also offers direct, precise, and reliable flow control. However, it is also available with a pneumatic actuator for integration into automated systems. In any case, the assembly is delivered tested and ready for installation.\u003c\/p\u003e\n\u003ch3\u003eOperating principle — Hygienic Diaphragm Valve\u003c\/h3\u003e\n\u003cp\u003eThe diaphragm is a flexible EPDM + PTFE membrane that separates the fluid zone from the sealing mechanism zone. When opened, the diaphragm lifts, allowing bidirectional fluid flow.\u003c\/p\u003e\n\u003cp\u003eWhen closed, on the other hand, the diaphragm compresses against the body seat and blocks the flow. In this way, the fluid never comes into contact with dynamic packing, lubricants, or moving metal parts.\u003c\/p\u003e\n\u003cp\u003eThis total separation also eliminates dead zones where product could accumulate between cycles. Therefore, the \u003cstrong\u003ehygienic diaphragm valve\u003c\/strong\u003e is the correct component when aseptic fluid integrity is a non-negotiable process requirement.\u003c\/p\u003e\n\u003ch3\u003eConstruction materials\u003c\/h3\u003e\n\u003cp\u003eThe body is made of 316L stainless steel, which is the standard material in high-purity applications. Its molybdenum content also offers greater resistance to chlorides and CIP agents than SS304. The diaphragm is made of EPDM + PTFE, which is the correct combination for aseptic processes.\u003c\/p\u003e\n\u003cp\u003eEPDM provides the necessary elasticity for hermetic sealing. PTFE also coats the face in contact with the fluid, ensuring total chemical inertness. Finally, the interior finish of Ra ≤ 0.2 µm is the most demanding in the family, which eliminates any roughness where microorganisms or residues could accumulate.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\n\u003cthead\u003e\n\n\u003ctr\u003e\n\n\u003cth\u003eParameter\u003c\/th\u003e\n\n\u003cth\u003eValue\u003c\/th\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/thead\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eValve type\u003c\/td\u003e\n\n\u003ctd\u003eDiaphragm | Bidirectional\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eBody material\u003c\/td\u003e\n\n\u003ctd\u003e316L Stainless Steel (SS316L)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eDiaphragm \/ Membrane\u003c\/td\u003e\n\n\u003ctd\u003eEPDM + PTFE\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eConnection\u003c\/td\u003e\n\n\u003ctd\u003eClamp 3A (quick coupling)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eInterior finish\u003c\/td\u003e\n\n\u003ctd\u003eRa ≤ 0.2 µm (mirror polished)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eWorking pressure\u003c\/td\u003e\n\n\u003ctd\u003e0 to 10 bar\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eMinimum temperature\u003c\/td\u003e\n\n\u003ctd\u003e-10 °C\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eMaximum temperature\u003c\/td\u003e\n\n\u003ctd\u003e110 °C\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eStandard control\u003c\/td\u003e\n\n\u003ctd\u003eManual\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eOptional control\u003c\/td\u003e\n\n\u003ctd\u003eManual only\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eCIP\/SIP compatible\u003c\/td\u003e\n\n\u003ctd\u003eYes\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\n\n\n\u003c\/table\u003e\n\u003ch3\u003eFluid compatibility\u003c\/h3\u003e\n\u003cp\u003eThis \u003cstrong\u003ehygienic diaphragm valve\u003c\/strong\u003e with an EPDM + PTFE diaphragm is compatible with the most demanding fluids in the sanitary industry.
