Mueller Company – Brass Curb Stops (Service Valves)
The MUELLER 300 Ball Valve is an optimized design combining a strong, reliable ball/stem connection with other desired features, including a blow-out-proof stem, double O-rings and a 300 psig working pressure rating. The design offers true bi-directional (two way) flow.
The MUELLER MARK II ORISEAL Curb Valve has a sturdy one-piece, closed-bottom body that differs from others designs by reducing the number of potential leakage points. The closed bottom design minimizes exposed moving parts. The large tee head and plug are integrally cast as one strong piece to resist twisting and breaking. In addition, the O-ring sealed design allows the plug to turn easily in the body, with a minimum of torque. The top and port O-rings are fully supported in machined grooves to provide positive sealing. All of these features combine in the MUELLER MARK II ORISEAL Curb Valve to provide reliable performance and long-term reliability. Mueller 300 Submittal , Mark II Oriseal Submittal
