WILKINS 475 4-10" RELIEF VALVE PITOT TUBE
PITOT TUBE ASSY,4-10" 475
DO NOT USE ON THE WILKINS 375 MODELS
Model Overview
This is a reduced pressure assembly. Production of the 2 1/2"-10" began in 1998. The 2 1/2"-10" check body is fused epoxy coated ductile iron. In 2010 all leaded bronze trim items were changed to lead free bronze. The checks are accessed from a single cover on the top which is attached with a grooved coupler. The checks are modularized so the springs will be contained when the cover is removed. The 2 1/2"-6" size checks are held in the body by retainer clips while the 8"-12" checks are bolted into the body. 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 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.
