    The Wilkins 350A and 350ADA are double check assemblies. Production of the 3/4"-2" began in 2004. The 3/4"-2" use a bronze housing which holds a glass field Noryl body containing the check mechanism. The checks are inline modular design. Spring tension is contained when the checks are removed from the body. Production of the 2 1/2"-10" began in 1998. The 12" began in 2007. The 2 1/2"-12" body is made of epoxy coated ductile iron. The check springs are contained. The checks are a glass filled Noryl. Modular checks are contained in the body by clips. The spring tension is contained when the checks are removed from the body. Do not relieve spring tension when changing the check discs. The model 350 is a straight horizontal piping orientation. The model 450 is able to be changed to provide an up and down or vertical piping orientation. Repair parts will be the same in both models. In 2004 the 350 became available in an "A" model. The A model uses a grooved end valve body configuration as opposed to a flanged end valve body.

    Wilkins 950 is a double check valve assembly. Production of the Wilkins 950 began in 1990. The 2 1/2"-10" sizes were discontinued in 2004. The 3/4"-2" size is a wye pattern glass filled Noryl poppet check. The body is bronze. The check springs are not contained. There were three versions of check seats produced. The Wilkins 950 version has a non-replaceable check seat. The Wilkins 950A had replaceable bronze seats. The model Wilkins 950 XL has replaceable seats made of glass filled Noryl. A seat removal tool is needed to change the seats. The check discs in the Wilkins 950 XL were changed to silicon. In 1997 a top entry model was created and called model Wilkins 950 XLT. The Wilkins 950 XLV, was created with union ends and 90 degree elbows on each end. The 2 1/2"-10" utilizes a fusion epoxy coated cast iron body. The check seats are replaceable and the spring is contained when the bolted cover is removed. The internal hardware parts are mostly bronze. The 2-1/2” – 10” were superseded by the 350 series.
