This is a double check assembly. Production began in 1993. The 3/4"-2" body is made of bronze and the 2 1/2"-10" size is a ductile iron body that is fused epoxy coated. There is a single cover on the top. The checks are modular in design. Check modules are held in the body with spring clips. Check seats are replaceable. In 2002 the model DCVE was introduced in sizes 3/4"-2" which is similar in construction as the DCV except the body is made of an unleaded bronze alloy. Most repair parts are the same.
