A gauge for a hybrid pressure and flowgauge regulator includes first indicia and second indicia. The first indicia provides an indication of a flow rate of a gas exiting an outlet of the hybrid pressure and flowgauge regulator when the gas exits with a pressure below a gauge threshold pressure. The second indicia provides an indication of the pressure of the gas exiting the outlet of the hybrid pressure and flowgauge regulator when the pressure of the gas exiting the outlet is above the gauge threshold pressure.

A valve position indicator for a valve includes a spline barrel, indicator flag, and follower. The spline barrel may be generally tubular and may be positionable about a tail stem protector of the valve. The spline barrel may have a helical slot formed therein. The spline barrel may be rotatably coupled to the tail stem protector of a valve. The indicator flag may be coupled to the spline barrel and may extend radially therefrom. The follower may be coupleable to a tail stem of the valve. The follower may extend in a direction perpendicular to the extent of the tail stem. The follower may extend through a slot in the tail stem protector and the helical slot of the spline barrel when the spline barrel is positioned about the tail stem protector.

A regulator includes a valve body and a control element movable between a closed position, in which the control element engages a valve seat, and an open position, in which the control element is spaced away from the valve seat. A stem is operatively coupled to the control element and is axially aligned with a longitudinal axis of the valve body. An indicator assembly is at least partially disposed in the valve body and is operatively coupled to the stem. The indicator assembly includes a rod operatively coupled to the stem and an indicator operatively coupled to the rod. The indicator is arranged to display a position of the control element. The rod of the indicator assembly is movable by the stem between a first position when the control element is in the closed position, and a second position when the control element is in the open position.

Provided is a valve for high-pressure gas, wherein a sheet member is provided inside a through hole formed in a valve body of the valve, wherein the sheet member constitutes a channel for high-pressure gas inside the through hole, wherein the sheet member is fixed inside the through hole by a pressing member, wherein an end opening of the through hole is closed by a lid member, wherein a gasket is provided at a peripheral part of the end opening of the through hole, wherein the gasket is sandwiched between the lid member and the valve body, wherein the lid member is pressed toward the valve body by a plug, and wherein a bearing is provided between the plug and the lid member.

An actuator position control system includes an electronic controller and encoder that control and monitor an actuator's position between its position limits, while mechanically actuated limit switches prevent attempts to exceed the actuator's position limits, even if there is a loss of calibration, software error, or electronic controller failure. When actuated, the limit switches provide position calibrating information to the electronic controller. Embodiments can control linear and/or rotary actuators. The encoder can include intermeshed gears and magnetic Hall-effect position sensors. A mechanically driven position indicator can visually indicate the actuator's position. An electromechanical control system can be included that can transition the actuator between its limits even in the event of electronic controller failure. Embodiments can alert a user if the electronic controller fails.

Exemplary embodiments are directed to butterfly valves, generally including a body assembly and handle assembly. The body assembly generally includes a body, a disc rotationally disposed inside an opening of the body, a cog, and a stem passing through the disc and the body. The handle assembly generally includes a handle body and a force ring. The stem can be rotationally interlocked relative to the disc and the handle assembly. The cog and the force ring can engage to rotationally secure the disc relative to the body. The handle assembly can include a lever and a grip, the force ring, the lever and the grip being pivotally secured relative to each other. The body can include a male radial protrusion and the body assembly can include a liner with a female radial groove. Methods of assembling and positioning a butterfly valve are also provided.

An open/closed display handle for rotating a spindle of an open/closed valve mechanism of a valve device includes a handle main body having a handle-side gear that rotates about an axis of the spindle, a rotary display body having an open/closed display portion that displays an open/closed valve state and a display body-side gear, and a rotary fixed body that pivotally supports planetary gears. The planetary gears, the handle-side gear, and the display body-side gear form a differential rotation mechanism, and a visual recognition restricting body that covers the rotary display body and has openings that open to allow a portion to be displayed of the open/closed display portion to be visually recognized from an outside and a transparent cover body that covers an entire outer side of the visual recognition restricting body and is translucent to allow visual recognition from an outer side form the handle main body.

A disc for indicating a position of a ball valve is provided herein. The disc includes a body having an outer circumferential edge and an inner circumferential edge. The inner circumferential edge defines an aperture configured to receive a valve stem. The disc further includes a first indicia and a second indicia circumferentially spaced about the outer edge of the body and circumferentially from one another. When connected to the ball valve, the first indicia is configured to indicate that the ball valve is in an open position and the second indicia is configured to indicate that the ball valve is in a closed position.

A low-volume non-rising stem gate valve comprising a hollow stem, planetary roller screw and anti-rotation rods. The anti-rotation rods isolate the torque force and maintain the alignment of the planetary roller screw with the stem and the screw shaft, thus reducing the amount of material necessary to support ordinary operational forces.

A valve position indicator for a valve includes an outer housing, actuation rod, indicator flag, and follower. The actuation rod is positioned within the outer housing, which is couplable to a tail stem protector of the valve. The actuation rod may have a helical slot formed therein. The actuation rod may be rotatably coupled to the outer housing. The indicator flag may be coupled to the actuator rod and may extend radially therefrom. The follower may be couplable to a tail stem of the valve. The follower may extend in a direction perpendicular to the extent of the tail stem. The follower may extend through a slot in the tail stem protector and into the helical slot of the actuation rod when the valve position indicator is coupled to the tail stem protector.
