Product Summary

Shutoff valves are safety valves used to close a line and stop the flow of material. Some types are manually closed; others are automated to act when a preset condition (such as a failure in the system) occurs.

A combined pressure-regulator and manual shut-off valve is described wherein the valve may be either manually shut-off or made operative to maintain a substantially constant outlet pressure under both flow and non-flow conditions. The device includes a piston and a disc both having substantially the same surface area and connected together with the disc being normally disposed on the outlet side of an opening between the outlet and inlet of the device, and the piston being movable within a cylinder against the action of a spring.

A rod is connected to the piston, and manual presetting means presets the rod either to one position wherein the disc is disposed within the opening between the inlet and outlet so that the device acts as a manual shut-off valve, or to another position wherein the disc is disposed on the outlet side of the opening and is urged by the spring away from the opening. In the latter position, the device acts as a pressure-regulator wherein an increase in outlet pressure causes the piston to move the disc towards the opening to regulate the outlet pressure during both fluid flow and non-flow conditions.
