  • Patent number: 9512927
    Abstract: A rapid-closure gate valve (10) comprising pressurized gas reservoirs (37, 39) that are integrated with the valve body (12). Pressurized gas stored in the reservoirs (37, 39) is utilized to shift a gate member (20) from a valve open position to a valve closed position upon actuation of the valve. Actuation of the valve is achieved by an actuator assembly (14) coupled with the valve body. The actuator assembly is configured to initiate a flow of pressurized gas from the reservoirs into a chamber (48) which effects shifting of the gate member.

  • Patent number: 9500289
    Abstract: Embodiments of a safety device that provides a failsafe mechanism on valve actuator assemblies. This failsafe mechanism operates in the event of power loss, or other problems and/or failures, that prevent operation of the drive components. In one embodiment, the safety device is configured to couple the drive components with the valve stem. During normal operation, this configuration changes the position of the valve stem in response to motive action of the drive components. In the event of power loss, the safety device is configured to operate independent of the drive components to change the position of the valve stem and, thus, move the valve to a closed or “safe” position.

  • Publication number: 20110072919
    Abstract: A displacement member can be displaced in a direction substantially perpendicular to a moving direction of a translation member that is held on a base member so as to reciprocatingly move thereon linearly, and an elastic mechanism secured to the base member accumulates and releases elastic energy in accordance with the distance to the displacement member. Protruding members of the translation member are pressed against a transmission member by generated force provided by the energy release from the elastic mechanism; thus, a distance adjusting operation between coupling mechanisms coupling the transmission member and the displacement member is controlled by a control device so that the relative position and relative angle between the displacement member and the transmission member are changed.
