Preset Flow Control
The operation of the flow control is based on the movement of a small disc. The flat surface on one side of the orificed disc seals and permits flow through the orifice. The amount of flow permitted in the reverse direction is determined by the orifice size. Orifice sizes are available from .004" to .040". In the forward direction full flow is permitted. The flow controls design allows a maximum supply pressure of 75 PSI with a cracking pressure of less than 10" H2O. The flow control... (read more)

and consumption. As the fluid enters the valve, it flows through the orifice to the outlet. The orifice and tapered piston create a venturi effect, accelerating the flow through the valve. At a preset flow rate, the pressure differential offsets the spring-loading of the piston and shuts off the valve. Fluid can flow through the valve in either direction; however, the flow will be shut off in the direction indicated on the valve. Adjustment is achieved by means of an externally adjustable screw...
