Abstract: A pressure regulating device including a valve body, an actuator assembly coupled to the valve body and including a diaphragm, a valve seat disposed in the valve body, a control assembly operatively connected to the diaphragm to move responsive to movement of the diaphragm, and a travel stop. The control assembly includes a control element that is movable, relative to the valve seat, between an open position, wherein the control element is spaced from the valve seat, and a closed position, wherein the control element sealingly engages the valve seat. The travel stop is configured to engage the control element to stop movement of the control element upon reaching the open position. The travel stop is adjustable to change the open position of the control element, such that a wide open flow capacity of the pressure regulating device can be adjusted.

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 shift closed in response to a pressure change. A valve body of the internal valve includes primary and secondary stem guides supported by respective primary and secondary stem struts connected to an inner side of the valve body. The valve body further includes thickened portions extending inwardly toward an axis of the valve body to which the secondary stem struts connect.

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: 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: Apparatus to interface with a corrugated profile are disclosed. An example apparatus for use with a fluid regulator includes an elastomeric ring having a corrugated profile that corresponds to a corrugated profile of a diaphragm of the fluid regulator. The elastomeric ring is to be positioned between a valve body and a bonnet of the fluid regulator to clamp the diaphragm between the valve body and the bonnet. The example apparatus includes a metallic ring positioned between the valve body and the bonnet to contact the elastomeric ring to support the elastomeric ring.
