A fluid control device has a body, actuator, and slam-shut device. The body defines an inlet, an outlet, and a plurality of slam-shut openings, and a seat is positioned along a flow path between the inlet and outlet. The actuator is configured to modulate a position of a first control element relative to a first side of the seat along an actuation axis to control a fluid pressure. The slam-shut device has a second control element that is movable along the actuation axis and is biased toward a second side of the seat and a slam-shut actuator configured to trigger the second control element to move to the closed position in which the second control element contacts the second side of the seat. The slam-shut actuator includes a shaft and the slam-shut actuator and shaft are positionable in any one of the plurality of slam-shut openings in different configurations.

Fluid-regulator with field convertible slam-shut device

Installing a fluid regulator in a fluid distribution system by: determining the position and orientation of the fluid regulator in the fluid distribution system; determining if a first opening and/or a second opening in the body of the regulator, are accessible with the fluid regulator in the determined position and orientation; installing the slam-shut device in the first opening, if accessible, and securing a plate over the second opening; and installing the fluid regulator in the fluid distribution system. The first and second openings are dimensioned such that the slam-shut device can be secured at least partially within the first opening in a first configuration and can be secured at least partially within the second opening in a second configuration.

Fluid regulator with field convertible slam-shut device

A fluid regulator includes an actuator assembly and a body secured to the actuator assembly. The body defines an inlet, an outlet, and a fluid passage disposed between the inlet and the outlet and includes a first opening and a second opening. The first opening is dimensioned to receive a portion of a slam-shut device and is formed through a first side of the body between the inlet and the outlet. The second opening is dimensioned to receive a portion of the slam-shut device and is formed through a second side of the body, opposite the first side, between the inlet and the outlet. A slam-shut device is positioned at least partially within the first opening, extends into the body, and is secured to the body and a plate is positioned over the second opening and secured to the body.

Methods and apparatus to access and align sealing discs are disclosed herein. An example apparatus includes a cage of a fluid regulator, where the cage has a central aperture, and a valve stem to be received by the central aperture. The example apparatus also includes a diaphragm coupled to the valve stem, where an integral protrusion of the cage is to constrain a peripheral edge of the diaphragm against a removable portion of a valve body when the cage is coupled to the valve body.
