General Description The TYCO Model CV-1F Grooved End Swing Check Valves are compact and rugged swing-type units that allow water flow in one direction and prevent flow in the opposite direction. A resilient elastomer seal facing on the spring-loaded clapper ensures a leak- tight seal and non-sticking operation. The Model CV-1F Check Valves are designed to minimize water hammer caused by flow reversal.The Model CV-1F Grooved End Swing Check Valves are furnished with grooved ends and can be installed using GRINNELL Grooved Couplings or GRINNELL Figure 71 Flange Adapt- ers. The Model CV-1F Check Valves have been designed with a removable cover for ease of field maintenance. These valves can be installed horizon- tally (with cover in the upward position) or vertically with the flow in the upward direction (Ref. Figure 4).
