Abstract:
A low pressure, low operating force valve, for applications where automated valves are used, having reduced power requirements for an associated actuator. A low torque ball valve of a fixed ball valve configuration for low to medium pressure applications, such as for an electric motor actuated residential shutoff valve where pressures are typically below 100 psi, and commonly less than 60 psi, for example. The valve can be open or shut using a smaller electric motor than would be required for a conventional residential floating ball shutoff valve of a similar size. As such, the power requirements of the electric motor or other actuator are reduced allowing for the use of smaller motors, smaller power supplies and overall more efficient operation.
