3S 3-A Sanitary Valve
Brand: Check-All Valve Manufacturing CompanyThe 3-A SANITARY (3S) valve is an electropolished 316/316L stainless steel check valve with a standard 32 Ra or better finish (consult the factory for finer finish availability) for use in new or existing sanitary systems.
This valve’s design seals on the ID of sanitary ferrules with 3-A specified materials. The valve seals inside fittings such as Alfa Laval Inc. Bevel Seat and Tri-Clamp, Waukesha Cherry-Burrell Q-Line and S-Line and others with ID dimensions equal to the "F" dimensions listed below (ferrules not included).
This valve is designed to be easily disassembled and cleaned. Spare parts are also available. The compact 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 3S valve can be used as a check valve or vacuum breaker. Please use "V" special option when ordering as a vacuum breaker. The standard spring material is 316 Stainless Steel.
