Description

This is a reduced pressure assembly. Production began in 1998. In 1997 the Watts Company purchased the Ames Company and began marketing the Ames 4000 SS as the Watts 994. The body is made of stainless steel with a single access cover for the checks. The check design is modular so springs are contained and the seats are replaceable. In the 2 1/2"-6" size the check assemblies are not field repairable and the whole check module must be replaced for an average repair. The check is made of glass filled noryl and is cam operated. The 8-10" check does have a rubber disc that is field replaceable. The relief valve is attached to the check body by threads and uses an external sensing line.
