Abstract: A control line stabilizer includes a body defining an inlet chamber, an outlet chamber, a passageway connecting the inlet chamber and the outlet chamber, a first seat, and a second seat. A disc is disposed in the passageway and is movable between a first closed position, in which the disc engages the first seat, an open position, in which the disc is spaced away from the first seat and the second seat, and a second closed position in which the disc engages the second seat. A first spring is disposed in the outlet chamber and is operatively coupled to the disc. A second spring is disposed in the inlet chamber and is operatively coupled to the disc. The disc restricts fluid flow through the passageway by moving to the first closed position and by moving to the second closed position.

Abstract: A regulator includes a body, a first cage positioned in the body, a diaphragm positioned within the body, and a second cage operatively connected to the diaphragm. The body has an inlet, an outlet, and a passage formed between the inlet and the outlet and the first cage is positioned adjacent the passage. The second cage moves with the diaphragm and is positionable on a first side of the diaphragm, opposite the first cage, or on a second side of the diaphragm such that the second cage is positioned within the first cage and is movable relative to the first cage.

Abstract: A slam-shut safety device including a valve body defining a flow path extending between an inlet and an outlet, a bonnet including a sleeve extending into the flow path and having one or more flow ports, an actuator arranged to detect an overpressure or underpressure condition, a control element movable between an open first position and a closed second position, a reset pin operatively coupled to the control element and movable between an un-tripped position, placing the control element in the open first position, and a tripped position, placing the control element in the closed second position, the reset pin configured to move from the un-tripped position toward the tripped position responsive to the actuator detecting the overpressure or underpressure condition, and a seal arranged to substantially prevent accumulation of particulates carried by fluid flowing through the one or more flow parts on the outer surface of the control element.
