Disclosed is a system and valve assembly that can be used to promote the laminar flow of a variety of fluids and gases. In one embodiment, the valve assembly can be used to remove entrained water bubbles from a water supply. This, in turn, increases the density of water running through an associated water meter. This ensures that the water meter is not inaccurately including entrained air as metered water. The result is more accurate water readings and reduced utility bills. The assembly can be externally adjusted using an adjustment tool so as to increase or decrease the tension on an interior spring which, in turn, increases or decreases the rate at which the interior block oscillates.

A touch spray head is in connection with a water supply segment of a water supply pipe which is accommodated in a body of a faucet and includes a water channel, the touch spray head and the water supply pipe are pulled out of and retracted back to an outlet of the body, and the touch spray head contains: a casing, a positioning member, a control valve, and an actuation device. The casing includes a hole arranged thereon, the positioning member includes at least one first through orifice, and each of the at least one first through orifice communicates with the water channel and the hole. The control valve includes a movable stem configured to turn on the control valve, and the actuation device partially exposes outside the casing and is operated by a user so as to urge the movable stem of the control valve to move.

A tire inflation assembly includes an air chuck that has a pair of outlets that has a direction of air flow which is oriented at a unique direction with respect to each other. In this way the air chuck can be attached to the valve stem at a variety of orientations to enhance employing the air chuck to inflate the tire. The air chuck includes a locking mechanism which engages the valve stem for retaining the air chuck on the valve stem. The locking mechanism is urgeable to disengage the valve stem to remove the air chuck from the valve stem. A pressure gauge is integrated into the air chuck to display the air pressure in the tire when either of the outlets is attached to the valve stem.

A mechanical system for calibration during a chemical feed process includes a ball valve that includes three openings. The ball valve is in communication with a lever, which when turned to a fill position, allows the filling of a drawdown cylinder for calibration. The ball valve automatically returns to its original default position within about a minute with a spring force automatically pushing it back to its start position.

A valve top includes a head piece which is centrally penetrated by a spindle which is rotatably mounted in the head piece around its longitudinal axis and via which a control disk can be rotated relative to an inlet plate abutting the same, wherein a control sleeve having a control contour is arranged within the head piece on the spindle, and a guide sleeve having a guide contour is arranged opposite the control contour, which control sleeve and guide sleeve interact in such a way that after actuation of the control disk via the spindle into a defined direction, an autonomous return movement of the control disk into its starting position is effected.

A faucet having a faucet base, a water hose, a faucet head, and a chamber is provided. A water valve is provided in the chamber and includes a driving member and a control valve movable between a first position enabling mixing of water and air and a second position enabling shut-off of a water flow. The faucet head further includes a push-to-rotate member movably coupled with the faucet head to enable operating the control valve within the water valve by operating the push member from or near a side of the faucet head.
