The present disclosure relates to a three-function check valve that in one embodiment is attached to a vacuum bladder full of media (foam beads). This three-function check valve is comprised of a selection piece, silicone membrane, and a mounting base all in one sub-assembly. Furthermore, this valve has three positions with three distinct functions. These functions are to create an airtight seal, allow for free flow in and out of the bladder, and restrict flow of air based on a differential pressure.

The present invention is an anti-entanglement knob for a self-contained breathing apparatus (SCBA) air cylinder valve, in which broadly comprises of an end terminating into a tapered shape on the side opposite from the SCBA air cylinder valve, and a guide/guard desirably located to guide objects to the tapered shape end, while also guarding undesired objects from entering between one or multiple components of the present invention and SCBA components. The present invention prevents entanglement by eliminating catching points and open areas that undesired objects, most commonly wires would usually be able to contact; furthermore objects are guided over and away from the present invention and the area of the SCBA that it is applied too.

A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

Retractable handle assembly used in a valve of an Intermediate bulk container (IBC) includes a valve body, a valve core, and a valve stem. The valve stem is used to drive the valve core to move so as to open/close the valve. The handle of the handle assembly is connected to the valve stem and can be rotated around the central rotating axis of the valve stem. When the valve needs to be opened/closed, the handle is rotated around the central rotating axis to a deployed state to open/close the valve. The handle is rotated around the central rotating axis to a retracted state so as to reduce the space occupied by the valve for the valve to be welded to the liner bag or installed to IBC. The handle can be switched between a deployed state and a retracted state.

Disclosed is a friction ring including a body and a contact member. The body is configured to couple the friction ring to at least one of a faucet assembly or a faucet valve assembly. The contact member is disposed on the body. The contact member is configured to slidably engage with a valve stem of the faucet valve assembly. The contact member is further configured to press against the valve stem to increase a frictional force between the contact member and the valve stem over a full range of movement of the valve stem.

A valve for preventing water hammer includes a speed reduction device for reducing a speed at which the valve may be closed. A method of preventing water hammer includes closing a valve at a fire hydrant after extracting water from the fire hydrant, in which the valve comprising a speed reduction device that increases an amount of time needed for closing the valve, and operating the valve to close the valve comprises operating the speed reduction device.
