ABSTRACT:
An apparatus utilizing a conventional pneumatic tire valve mounted concentrically within a resilient seal for cooperative action with a seat structure to accomplish three-way valve operation effective in pressurizing and relieving a chamber of a dispensing gun as for mastic material. A valve seat member: defines a flow passage, affords a flat surface about the passage for seating engagement with the resilient seal member, and receives a set screw for engaging the core of the conventional tire valve. The tire valve and the resilient seal member are fixed on a handle that is pivotably mounted with respect to the seat member to afford relative motion with respect to the seat member for variously actuating the valve.
