    摘要： 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.

    摘要： A fluid regulator having a valve body defining an inlet, an outlet, a loading port, an access port, and a loading chamber disposed within the valve body and coupled to the loading port. A valve assembly is at least partially disposed between the inlet and the outlet and in communication with the loading chamber and is adapted to cooperate with the loading chamber to adjust fluid flow at the outlet by adjusting a fluid flow rate between the inlet and the outlet. A restrictor is at least partially disposed within the access port and the loading chamber and the valve assembly are adapted to be responsive to a change in loading pressure such that a modified rate is achieved and the restrictor is adapted to adjust a response speed in which the modified rate is achieved.

    摘要： A fluid flow valve includes a valve body, a loading chamber disposed within the valve body, a valve assembly, and a restrictor unit. The valve body defines a flow inlet, a flow outlet, and a loading chamber inlet. The loading chamber is coupled to the loading chamber inlet. The valve assembly is at least partially disposed between the flow inlet and the flow outlet and is in communication with the loading chamber. The valve assembly is adapted to cooperate with the loading chamber adjust fluid flow at the flow outlet by adjusting a fluid flow rate between the flow inlet and the flow outlet. The restrictor unit is at least partially disposed within the loading chamber inlet. The loading chamber and the valve assembly are adapted to be responsive to a change in loading pressure to achieve a modified fluid flow rate. The restrictor unit is adapted to adjust a response speed in which the modified fluid flow rate is achieved.

    摘要： Fluid control apparatus having flow restrictors are described herein. An example actuator includes an actuator housing having an actuator to define a first chamber of the actuator housing and a second chamber of the actuator housing. A loading fluid pathway is formed in the actuator housing to fluidly couple a loading fluid and the first chamber. A restrictor is positioned within the loading fluid pathway to regulate a flow rate of the loading fluid that is to flow from an inlet port of the loading fluid pathway to the first chamber.
