The Mueller Co MARK II ORISEAL® Curb Valve has a sturdy one-piece, closed-bottom body that differs from other 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.
