  • Pressure testing apparatus for gas service delivery systems
    Patent number: 6719002
    Abstract: A gas delivery system for propane or natural gas includes a gas service line, a pressure regulator connected in the gas service line, and a flow control valve device permanently installed at a predetermined location in the gas service line, e.g., upstream of the regulator or downstream of a gas meter in the case of a natural gas system. The flow control valve device includes a valve body incorporating an integral pressure tap for enabling a measurement of gas pressure at the predetermined locations. The valve device also includes a valve operator having an open position in which flow takes place through the valve device and a closed position in which flow through the valve device is blocked and a locking mechanism with a specialized key issued only to service personnel for selectively locking the valve operator in the open and closed positions.
