Abstract: A valve which can be applied to a water pipe while the pipe remains in service. The body of the valve is formed in two sections which can be applied to the outside surface of the water pipe and secured together in precise alignment with one another by tapered pins. A reciprocating gate which forms the valve element is bifurcated and includes a pair of gate sections carrying knife edges which cut through the pipe wall when the gate is initially moved to its closed position. This cuts away a ring from the water pipe and permits the gate to function to control water flow through the valve. The scrap ring which is cut away from the pipe is forced by the gate into a cavity disposed out of the flow line. The gate crushes the ring against a complemental convex surface of the cavity. Camming interaction between the leading ends of the gate sections and the convex surface mechanically forces the gate sections away from one another to press them firmly against the valve seats when the gate is fully closed.
