    375XL

    Wilkins 375 Composite body backflow assembly is designed for installation on potable water lines to protect against both backsiphonage and backpressure of contaminated water into the potable water supply. Assembly shall provide protection where a potential health hazard exists. Ideal for use where Lead Free* valves are required.

  • 375ST

    375ST

    Wilkins 375ST was designed for installation on potable water lines to protect against both backsiphonage and backpressure of contaminated water into the potable water supply. The Model 375ST provides protection where a potential ealth hazard exists. The valve's stainless steel construction is ideal in those systems that utilize liquids corrosive to copper alloys. Potential applications include: medical diagnostic equipment, food processing, distilleries, breweries, etc. Additionally, the 375ST is ideal for applications requiring valves that are lead-free*.

    975XL2

    The Wilkins 975XL Backflow Preventer is a reduced pressure assembly. Production of the Wilkins 975XL model began in 1990. Starting in 2004 in sizes 3/8" and 1/2" a stainless steel body assembly was also produced. The 3/4"-2" size is a wye pattern poppet style check design with the disc holders made of a glass filled Noryl. The relief valve has an internal relief valve sensing line. The body of the Wilkins 975XL is bronze. There are three versions of check seats available. The 975 version was discontinued in 1992 and had a non-replaceable check seat. The model 975A was discontinued in 1992 and had a replaceable bronze check seat. The model Wilkins 975XL began production in 1993 and had a replaceable check seat made of glass filled Noryl. A seat removal tool is needed. The check discs in the Wilkins 975XL were changed to silicon. The relief valve seat is replaceable. Checks and relief springs are not contained. Ideal for use where Lead Free* valves are required.

  • 375A

    375A

    The Wilkins 375 backflow preventer series are reduced pressure assemblies. The checks are an inline modular design. The relief valve uses an internal sensing line. Production of the 2 1/2"-10" began in 1998. The 2 1/2"-10" check body is fused epoxy coated ductile iron. The checks are accessed from a single cover on the top which is attached with a grooved coupler. The checks of the Wilkins 375 backflow series are modular. The springs are contained when the cover is removed. The checks are a glass filled Noryl modular construction and are retained in the body by clips. The spring tension is contained when the checks are removed from the body. Spring tension does not have to be released to change the check discs. The relief valve utilizes an external sensing line. The relief valve body is made of bronze. The relief valve spring is not contained when the cover is removed. The Wilkins model 375 is a horizontal piping orientation. The Wilkins model 475 is able to be changed to provide an up and down or vertical piping orientation. The repair kits for both models will be the same. In 2004 the Wilkins model 375 became available in an "A" model. The Wilkins 375A model uses a grooved end valve body configuration as opposed to the flanged end valve body
