  • Service regulator with improved boost performance
    Patent number: 8156958
    Abstract: A regulator comprises a regulator valve and an actuator. The regulator valve comprises a valve body equipped with a customized valve port. That is, the valve seat is designed to have a customized seat height depending on a diameter of an orifice through the valve port, a longitudinal dimension of an orifice through the valve port, and/or a flow capacity of the valve port. Such a design advantageously maximizes the efficiency at which gas flows through the regulator. The actuator is coupled to the valve body and comprises a valve disc disposed within the valve body and adapted for displacement between a closed position engaging the valve seat and an open position spaced from the valve seat.
