A system including a valve. The valve includes a valve body having an interior volume and a bore along a first axis. A stem extends along a second axis and a flow control element couples to the stem. The stem selectively moves the flow control element through the interior volume between a closed position and an open position relative to the bore. A valve insert system retains a pressurized lubricant in the interior volume.

A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

The present disclosure relates to a rotary plug valve and, more particularly, to a rotary plug valve having a fluid conduit cartridge including components that are assembled in a manner allowing for the rotation of a valve handle without rotation of the entire valve or supply line. Illustratively, a retainer ring and a backer ring are coupled with a gripper ring positioned therebetween. Coupling of the retainer ring and the backer ring creates compression on locking tabs of the grip ring, holding the locking tabs in place between tangs of the backer ring and preventing rotation of the gripper ring.

A valve assembly includes a valve body defining an interior cavity extending to a bonnet portion, a valve stem including a valve element retained in the interior cavity of the valve body and an end portion extending beyond the bonnet portion, the valve stem being rotatable between a first limit position and a second limit position, and a spring return handle arrangement. The spring return handle arrangement includes a user graspable valve handle, a stem adapter, and a return spring. The stem adapter includes a first end portion secured to the valve stem and a second end portion secured to the valve handle. The return spring includes a first end portion secured to the valve body, an intermediate spring loaded portion, and a second end portion secured to the stem adapter to apply a torsional load to the stem adapter for returning the valve stem to the first rotational limit position.

An annulus pressure release system includes a gas metering valve assembly having a fluid pathway. The gas metering valve assembly includes a pressure sensor configured to be fluidly coupled to an annulus and to output a sensor signal indicative of a fluid pressure within the annulus. The gas metering valve assembly also includes an electronically actuated adjustable control valve disposed along the fluid pathway and a electronically actuated two-position valve disposed along the fluid pathway. Furthermore, the gas metering valve assembly includes a flow controller. The flow controller, in response to determining the fluid pressure exceeds a threshold pressure, is configured to output a first control signal to the electronically actuated two-position valve indicative of instructions to open the electronically actuated two-position valve, and to output a second control signal to the electronically actuated adjustable control valve indicative of instructions to adjust a flow of fluid through the fluid pathway.

A fluid control device includes a body having an inlet, an outlet, and a fluid flow path between the inlet and the outlet, a seat, and a control element that is coupled to a stem. The control element and the stem are movable along a first axis and biased toward a closed position in which the control element engages the seat. The fluid control device includes an actuator assembly including a shaft that is operatively coupled to the stem via a Scotch yoke mechanism such that rotation of the shaft in a first rotational direction causes movement of the stem and control element along the first axis in a first translational direction. The actuator assembly includes a trigger mechanism that is responsive to fluid pressure and prevents rotation of the shaft in a first mode of operation and releases the shaft to allow rotation in a second mode of operation.
