ABSTRACT:
A control valve assembly and for a gas delivery system is disclosed comprising a valve housing and piping combination adapted to mate with a gas meter outlet, the valve including a main inlet and an auxiliary inlet for bypassing the main inlet, and a poppet disposed within the housing for selectively opening the respective inlets and for closing both inlets. The poppet is controlled by a valve stem extending into the valve housing and coupled to the poppet, such that rotation of the valve stem orients the poppet in the predetermined positions to selectively open the respective inlets. The valve stem is rotated using a lever arm extending radially from the valve stem, where the lever arm is adapted to carry a locking member at a distal end. When the locking member is carried by the lever arm, rotation of the lever arm may be denied due to interference of the locking member with the valve housing, and the poppet in such case prevents flow through either of the inlets.
