375AST

Sizes

2 1/2", 3", 4", 6"

Description

This is a reduced pressure assembly. Production began in 2011. This assembly is similar to the model 375A except the check body is fabricated from stainless steeltubing. There is a single access cover for the check valves on the top. The cover is attached by a grooved end coupling. The check valves are of a modular construction made of glass filled noryl. The 2 1/2"-6" size check modules are retained in the body by retainer clips. The checks of the 8"-10" size are bolted into the body. The check modules are repairable for replacement of the check disc. The relief valve body is made of a lead free bronze and attached under the check body. The design uses an external sensing line to the relief valve. The relief valve cover is bolted to the relief valve body and there will be spring tension on the cover when it is removed.
