A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit including a collection of valve shutter(s) comprising at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve including a mechanism for manually controlling the collection of valve shutter(s), the control mechanism being mounted with the ability to move on the body between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control mechanism actuates the collection of valve shutter(s) into a position in which the circuit is open to a first bore section.

Pressure testing systems comprise a clamp assembly for clamping a device for testing with a test fluid, and a control assembly for controlling application of a clamp pressure to the device. The control assembly comprises a clamp control structure with an activated configuration and an inactivated configuration. In the activated configuration, the clamp control structure permits the clamp pressure to be applied to the device. In the inactivated configuration, the clamp control structure permits the clamp pressure to be released from the device. The control assembly also comprises a safety structure that is actuated by the test fluid between an interlocked configuration and a disengaged configuration. In the interlocked configuration, the safety structure physically prevents the clamp control structure from reconfiguring from the activated configuration to the inactivated configuration. In the disengaged configuration, the safety structure permits the clamp control structure to be reconfigured from the activated configuration to the inactivated configuration.

Valve handles and dual-valve assemblies having handles are disclosed herein. An example dual-valve assembly includes a first valve having a first shaft. The first valve has a plate with a notch. The dual-valve assembly also includes a second valve having a second shaft. The dual-valve assembly further includes a handle coupled to the first and second shafts, such that when the handle is rotated, the first and second shafts are rotated simultaneously. The handle includes a body and a flexible arm coupled to and extending from the body. The flexible arm has a lock edge sized to fit within the notch to limit rotation of the handle relative to the first and second valves.

A switching valve includes a base including a bottom wall and a side wall that extends from the bottom wall of the base along a circumferential direction of the bottom wall, a body that can couple to the base to define a cavity between a bottom plate of the body and the bottom wall and the side wall of the base, in which the bottom plate includes two through holes that are each fluidly coupled to the cavity, two sliders disposed within the cavity, and two driving rods each movably coupled to one of the two through holes of the body, in which each driving rod can move relative to the two through holes to block or unblock each respective through hole. Each slider can slide responsive to movement of one of the two driving rods such that only one through hole is unblocked at one time.

Systems and methods are provided herein for restraining sink and shower handles. One or more faucet handle cuffs with a flexible member inserted within fits over a one or more faucet handles. The faucet handle cuffs slide along a tether that secures the faucet handle cuffs into place, preventing the faucet handles from being rotated into an on position. The faucet handle cuffs are locked into place on the tether via a lock positioned on the cuffs that secures the cuffs to the serrated teeth on the tether.
