OS&Y gate valve is used to regulate the flow of water to fire sprinkler systems.
The outside and interior are both coated with a superior fusion-bonded (thermosetting) powder epoxy that is nominally 10 mils thick.
Flats cast into the bottom of the valve body let it stand up straight when it’s being stored or put in place.
Mueller’s design has two thrust washers and has consistently shown to be stronger than cast stems.
Offers an exceptional level of bonnet sealing (4″ – 12″ sizes).
Mueller OS&Y Gate Valveprovides a bearing surface between the enclosed wedge and the inner epoxy coating, minimizing operating torque and improving valve service life.
The waterway’s bottom has no grooves or recesses which could gather silt or debris and weaken the seal.
Mueller a2361 allows for full-sized shell cutters to be used with plenty of room during tapping operations.
