Abstract: 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.

Abstract: A spring adjusting device and a valve assembly including the same. The spring adjusting device includes an adjusting screw rod, a spring, and a spring seat which is located between the adjusting screw rod and the spring. A groove is arranged in the spring seat, which can contain an end part of one end of the adjusting screw rod, and is provided with a cylindrical side wall. The spring adjusting device can prevent the end part of the adjusting screw rod from being separated from the groove, and the spring from being bent on the whole, thereby improving the overall working performance of the valve assembly.

Abstract: A balanced port pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway, an orifice being disposed between the fluid inlet and the fluid outlet. A valve seat is disposed within the fluid passageway. A valve plug is also disposed within the fluid passageway. A piston is disposed within the valve body, the piston separating the fluid passageway from a balancing chamber. A sleeve extends away from the piston, the sleeve forming a balancing passage that fluidly connects the fluid passageway with the balancing chamber. The sleeve includes an open end that terminates within the orifice. By terminating within the orifice, the open end of the sleeve generates boost only towards the end of a valve opening cycle when the valve plug approaches a fully open position, which is where boost is most needed.

Abstract: Example noise attenuators for use with process control devices are described herein. An example apparatus includes a first plate and a second plate disposed in a fluid passageway of a noise attenuator. The second plate is spaced apart from the first plate. The example apparatus also includes a first support rod extending along a central axis of the fluid passageway. The first support rod is coupled to the first plate and to the second plate. The example apparatus further includes a second support rod extending along an axis parallel to and offset from the central axis. The second support rod is coupled to the first plate and the second plate.

Abstract: A trapezoidal thread form includes a thread having a trapezoidal cross-sectional shape, the thread including an apex surface, two side surfaces, and a valley; and a thread wear indicator formed in one of the apex surface and one of the side surfaces. The thread wear indicator may include a v-shaped channel formed in one of the apex surface and one of the side surfaces or the thread wear indicator may include a series of material layers, each layer having a physical characteristic that is different from an adjacent material layer. The thread wear indicator indicates excessive or unsafe thread wear when the v-shaped channel is indistinguishable from the apex surface or the side surface, or when a first layer wears sufficiently to show a second layer.

Abstract: An in-line serviceable cutoff valve with excess flow capability includes a valve body and a separable cover. Internal valve components are accessible for service or replacement when the separable cover is removed from the valve body. The internal valve components may optionally be attached to the separable cover so that the separable cover and the internal valve components may be removed as a single assembly.

Abstract: A valve plug assembly adapted for sealing engagement with a seat ring. The valve plug assembly includes a valve plug having a sealing disk adapted to engage a seating surface the seat ring. The seating surface of the seat ring has a primary portion with a primary angle of any one of about 20 degrees to about 45 degrees and a secondary portion extending from the primary portion with a secondary angle of about 10 degrees. A retainer is coupled to the valve plug and includes a body having a first portion, a second portion, and a side extending from the first portion to the second portion at one of an angle of about 30 degrees to about 45 degrees. So configured, the stress acting on the sealing surface is reduced, increasing the service life of the sealing disk.

Abstract: An internal valve includes a valve stem disposed in a valve body, a poppet valve coupled to the stem, and a bleed valve coupled to the stem. The valve stem is shiftable from a first position in which the poppet valve and the bleed valve are closed, to a second position in which the bleed valve is open, and a third position in which the bleed valve is closed and the poppet valve is open, and the poppet may close in response to a pressure change. The internal valve includes a strainer having an extended portion to be positioned in a clearance space between an upper portion of the valve body and an opening of a fluid container. The strainer is arranged for securement to a mounting area of the valve body by at least one fastener.

Abstract: 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.
