Located between the corporation valve and the new service structure, Mueller curb valves and boxes allow easy access to shut off or turn on water going into a building or residence. These products provide years of trouble-free service without replacement or special attention, helping to control rising maintenance costs. We offer a wide variety of styles including the Mueller 300 ball-type, Oriseal®, Mark II Oriseal, Oriseal III, inverted key, and solid tee curb valves. For curb boxes, extension types are available with arch and Minneapolis pattern base.
