3-A Sanitary Check Valve Style - 3S
The 3-A Sanitary Check Valve is an all 316/316L stainless steel check valve with a standard 32 Ra or better finish, (finer available) for use in new or existing sanitary systems. The 3SC design seals on the ID of sanitary ferrules with 3-A specified materials (standard is EPDM). The valve seals inside fittings such as Tri-Clover® Bevel Seat, and Tri-Clamp®, Waukesha Cherry-Burrell Q-Clamp®, and S-Line® and others with ID dimensions equal to the "F" dimensions listed. The valve is designed to be easily disassembled and spare parts are available. The compact 3SC design fits inside a single set of ferrules, and requires no additional space in the line. The insert design makes it extremely economical when compared to full-bodied valves. The wide variety of seat materials and cracking pressure springs allows this series to be used as a check valve or vacuum breaker. Please specify when ordering.
