Description

This is a double check detector assembly. Production of the 2 1/2"-10" began in 1998. The 12" began in 2008. The mainline assembly utilizes an assembly similar to the 350 or 450. The bypass utilizes an assembly similar to the 950 XLD. The model 350 DA is a straight horizontal piping orientation and comes in sizes 2 1/2"-12". The model 450 DA is able to provide an up and down or vertical piping orientation and comes in sizes 4"-10". Repair kits will be the same for both models. In 2004 the 350 DA became available in an "A" model (e.g. 350ADA). The A model uses a grooved end valve body configuration as opposed to the flanged end valve body.
