The present disclosure relates to a hydrostatically adjustable flow control valve. In one embodiment, the valve includes a fixed sleeve that slidably receives a spool. A spring biases the spool relative to the fixed sleeve. A primary orifice is used to deliver fluid to the interior area of the fixed sleeve and spool. A control device is used to selectively vary the rate at which fluid drains from the interior area. Draining the fluid results in the spool being received within the interior of the fixed sleeve. The movement of the spool opens flow ports within the sleeve. This, in turn, allows fluid to exit the valve. Conversely, the control device can be set to prevent fluid drainage. This results in the spool extending from interior of the fixed sleeve, the closure of the flow ports, and the sealing of the valve.

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.

Externally adjustable flow management valve assembly and system
A system and valve assembly that is adapted to increase the efficiency of an upstream water meter. By way of the valve assembly entrained water bubbles can be removed from a water supply. This, in turn, increases the density of the water running through the 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.
