Its design combines butt-weld ports—which eliminate leaks and dead zones—with a clamp-removable body.\u003c\/p\u003e\n\u003cp\u003eThis allows for inspection, cleaning, and replacement of the Viton seal without special tools. Therefore, it is the correct solution for the food, pharmaceutical, cosmetic, and chemical industries. In these sectors, reflux control and hygiene are non-negotiable requirements.\u003c\/p\u003e\n\u003cp\u003eIts Viton seat also withstands temperatures up to 180 °C and a wide range of chemical agents. Consequently, it guarantees a hermetic and long-lasting seal even under extreme process conditions.\u003c\/p\u003e\n\u003ch3\u003ePrinciple of Operation — Sanitary Weld Check Valve\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003esanitary weld check valve\u003c\/strong\u003e operates automatically and without external actuation. When the fluid flows in the correct direction, the pressure overcomes the spring force, thus opening the disc and allowing passage.\u003c\/p\u003e\n\u003cp\u003eWhen the flow ceases, however, the spring returns the disc to the Viton seat. The valve closes immediately and automatically, thereby protecting the line against any fluid return without operator intervention.\u003c\/p\u003e\n\u003cp\u003eThe butt-weld ports also eliminate leak points and dead zones that exist in clamp or threaded connections. For this reason, they are the preferred type of connection in CIP\/SIP systems and aseptic processes where circuit integrity is critical.\u003c\/p\u003e\n\u003ch3\u003eThe Differentiating Advantage — Weldable with Removable Body\u003c\/h3\u003e\n\u003cp\u003eThis valve combines the advantages of two connection systems that usually exclude each other:\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eWeldable ports:\u003c\/strong\u003e The connection to the pipe is permanent and without external gaskets, thus eliminating all possible leak points in the connection. Consequently, it is the preferred type of connection in high-purity aseptic lines where external contamination is unacceptable.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eRemovable body with clamp:\u003c\/strong\u003e Despite the welded connection to the pipe, the valve body can also be completely disassembled using the clamp. Therefore, inspection, cleaning, and replacement of the Viton seal are performed without cutting or modifying the pipe. Likewise, maintenance time is significantly reduced compared to check valves with non-removable bodies.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eConstruction Materials\u003c\/h3\u003e\n\u003cp\u003eThe body is made of 316L stainless steel, which is the standard material in demanding hygienic applications. Its molybdenum content also offers greater resistance to chlorides and CIP agents than SS304. The disc is also made of SS316L, maintaining material consistency throughout the fluid contact area.\u003c\/p\u003e\n\u003cp\u003eThe seal is made of Viton (FKM), which is compatible with temperatures up to 180 °C. It also resists acids, alkalis, and CIP agents that would degrade NBR or EPDM. Finally, the Ra ≤ 0.8 µm internal finish is the sanitary standard that eliminates surface roughness where microorganisms or product 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\u003eSpring Check — Unidirectional Retention\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\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eDisc\u003c\/td\u003e\n\n\u003ctd\u003e316L Stainless Steel\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eSeal (Seat)\u003c\/td\u003e\n\n\u003ctd\u003eViton (FKM)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eConnection Ports\u003c\/td\u003e\n\n\u003ctd\u003eButt-weld\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eBody Disassembly\u003c\/td\u003e\n\n\u003ctd\u003eClamp\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eInternal Finish\u003c\/td\u003e\n\n\u003ctd\u003eRa ≤ 0.8 µm\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 (0 to 145 psi)\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-20 °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\u003e180 °C\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\u003esanitary weld check valve\u003c\/strong\u003e with Viton seal is compatible with the most demanding fluids in the sanitary industry.
