  • Patent number: 8770442
    Abstract: An O-ring retainer is disclosed that is integral with a valve stem of a valve. The valve is intended to move in a valve chamber, which valve chamber has a fluid inlet and a fluid outlet. When manually actuated, the valve moves between a first position, where it is seated against walls of the valve chamber and prevents flow through the chamber, and a second unseated position where it allows flow of the fluid through the chamber between the inlet and the outlet. An O-ring, used in conjunction with the valve and the valve chamber, is maintained in place by an outward projection from the valve stem, which projection is located just below the normally seated O-ring. Thus, if the O-ring becomes unseated, the projection, upon movement of the valve towards the seated position, bumps the O-ring back into its normal position.

  • Patent number: 8348228
    Abstract: A high pressure metering valve has a valve element with a closing portion, a metering portion and a rapid return portion. The closing portion seats against a corner seat at the end of a valve bore in which the metering portion has a close sliding fit. When the element is unseated, a flow rate can be metered depending on the overlapping length of the metering portion in the valve bore. At the opposite end of the metering portion, the rapid return portion is undercut to be of smaller area than the metering portion to provide a full open state for rapid fluid return.

    Abstract: Provided in some embodiments is a system that includes a split gate valve including first and second gate sections coupled together and configured to move together within a cavity of the split gate valve between an open position and a closed position. The split gate valve includes a rolling actuator to reduce friction and to convert a rotational input into a linear motion to move the first and second gate sections between the open and closed positions. In other embodiments is provided a method that includes converting a rotational input into a linear motion to activate a split gate valve via a rolling actuator. The method also includes seating first and second gate sections of the split gate valve against opposite first and second seats to provide a double seal.

  • Publication number: 20120248362
    Abstract: A pressure relief valve for use in regulating discharge fluid pressure of a pump includes a casted, metal material housing including a passage therein along a longitudinal axis and inlet and outlet ports substantially perpendicular to the longitudinal axis and each having walls that are at an angle less than perpendicular to the longitudinal axis wherein the angle of the wall from being perpendicular to the longitudinal axis is substantially equal to the draft angle from the casting of the housing. A first wall of the outlet intersects with the wall of the passage of the pressure relief valve. A valve body disposed in the passage is movable in the passage against the biasing force of a spring biasing the valve body in a first or closed direction wherein the inlet port and the outlet port are disconnected, until the force at the inlet applied to the valve body overcomes the biasing Force of the spring and the inlet fluid is communicated through the passage and to the outlet.
