The Grinnell® model 590 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. They are manufactured with a ductile iron body and a nickel-plated seat. A resilient elastomer seal facing on the spring-loaded clapper ensures a leaktight seal and a non-sticking operation. The model 590 check valves are designed to minimize water hammer caused by flow reversal. The model 590 check valve is furnished with grooved ends and can be installed using Grinnell® grooved couplings or flanged adapters. The model 590 check valves have been designed with a removable cover for ease of field maintenance. These valves can be installed horizontally (with cover in the upward position) or vertically with the flow in the upward direction.
