The 3-A sanitary valve from Check-All is an all 316/316L stainless-steel check valve with a standard 32 Ra or better finish for use in new or existing sanitary systems. The 3SC design seals on the ID of sanitary ferrules with 3-A specified materials (the 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.

It 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 the valve quite 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.
