■ Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through
the valve in proportion to the square root of the pressure differential across ports 1 and 2.
■ The sharp edged orifice design minimizes flow variations due to viscosity changes.
■ There is no leakage when the adjustment mechanism is turned to the shut-off position.
