Check-All SIV Non Return Valve

The Sanitary Insert Valve is an all TEFLON® resin check valve with a 316 stainless steel spring (which can be TEFLON® resin 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 over 30 years, the compact, TEFLON® resin, 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. 
Two different types of Sanitary Insert Valves are available.  They are distinguished by the following designations in their part numbers:        

TC - Designates fittings manufactured by Tri-Clover® Inc.  as well as S-Line® fittings manufactured by Waukesha Cherry-Burrell.  
CB - Designates the Q-Clamp® Series of fittings manufactured by Waukesha Cherry-Burrell.
