3/4" AISI 316L Stainless Steel Sanitary Check Valve Polished Sanitary Valves
Stainless sanitary ball check valves are designed to allow full product flow during processing. Once the product flow stops the ball rolls back to the seat at inlet preventing backflow. Stainless steel sanitary ball check valves are commonly used with liquid products. Sanitary ball check valves are available standard in clamp or weld ends, but others are available per request. Sanitary ball check valve replacement parts are available upon request. Buna gaskets are standard, but Viton gaskets are available upon request.
Sizes are available from 1/2" to 4" (1/2", 3/4", 1”, 1 1/2", 2", 2 1/2", 3", 4")
DN15 to DN100 (DN15, DN20, DN25, DN40, DN50, DN65, DN80, DN100)
Valve body can be AISI 304 or AISI 316L.
Valve seat: EPDM, VMQ (silicone), Viton (FPM).
End connection can be butt-welded, sanitary clamp, threaded or others upon request.
Max. working pressure: 145psi (10bar)
Opening pressure: 4.5psi/0.3 bar (DN25/1"), 3 psi/0.2 bar (DN32/0.75" to DN40/1.5"), 1.5 psi/0.1 bar (DN50/2" to DN100/4")
Working temperature range: 14 ~ 248°F (-10 ~ 120°C) with EPDM seat.
Surface treatment: Ra 32μin (0.8μm) as default, others available upon request.

Are different to many other types of valves,for check valves work automatically and most are not controlled by a person or any external control. Accordingly, most do not have any valve handle or stem. Thus there is an important concept in check valves, it is, the cracking pressure. Cracking pressure is the minimum upstream pressure at which the valve will operate. So the check valve is designed for and can therefore be specified for a specific cracking pressure.
