Product Announcement from Check-All Valve Mfg. Co.
For nearly 30 years, the compact, PTFE, 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.
