WILKINS 575/975 1 1/4-2" #1 CHECK SPRING

SPRING #1, 1 1/4" XL. This is an original manufacturer repair product used within various divisions of Zurn Industries or previously private labled under another manufacturer.

Model Overview

This is a reduced pressure assembly. Production began in 1990. Starting in 2004 in sizes 3/8" and 1/2" a stainless steel body assembly was produced. The checks are similar to the one used in the 950 design. 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 is constructed of bronze. In 2010 a 975XL2 was introduced which is made of lead free 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 975XL began production in 1993 and had a replaceable check seat made of glass filled noryl. A seat removal tool was needed to change the seats. The check discs in the 975XL were changed to silicon rubber. In 2001 the 975XL was made available with a stainless steel body in sizes 3/8"-1/2". The relief valve seat is replaceable. Checks and relief springs are not contained when the covers are removed.
