Sanitary Check Valves

Style 3SC (3S)
3-A Sanitary Check Valves are an all 316 stainless steel check valve 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 below. This valve is designed to be easily disassembled and spare parts are available.

Check-All style 3SC sanitary check valves are compliant with 3A Sanitary Standards for Vacuum Breakers and Sanitary Check Valves for Milk and Milk Products, Number 58-00. Among other requirements, this is a standard that requires a 32 Ra finish and specified groove angles and depths, all for sanitary purposes.

The Sanitary Cartridge Valve is a 316 stainless steel check valve for use in new or existing sanitary systems. The SCV design seals on the ID of sanitary ferrules with replaceable food grade seals (Standard is FDA EPDM). The valves fit the Tri-Clover Bevel Seat and Tri-Clamp fittings, the Cherry Burrell Q-Clamp and S-Line fittings, and other manufactures' fittings as long as they have ID's equal to the C dimension listed in the Sizes & Dimensions table below.

The compact SCV design fits inside a single fitting, and requires no additional space in the line. Its size makes it extremely economical when compared to full-bodied valves.

Choose from Check-All's broad selection of seat materials and cracking pressure springs that allow this series to be used as a check valve, relief valve, or a vacuum breaker.

Style SIV (CB, TC)
The Sanitary Insert Valve is an all fluoropolymer (PTFE/FEP/PFA), check valve with a 316 stainless steel spring (which can be FEP encapsulated) for use in new or existing sanitary systems. The valve is designed to fit into grooved end clamp type fittings and replaces the gasket normally used with these fittings.

For nearly 30 years, the compact, Teflon®, Sanitary Insert Valve has been used as the most economical solution to providing a check valve in a new or existing sanitary piping system. This valve style is designed to fit into grooved-end clamp-type fittings. Since the Sanitary Insert Valve replaces the gasket normally used with clamp joints, no extra space is required to accommodate the valve.
