These fittings have an internal bush, with a calibrated hole whose diameter results in a flow restriction. Typical uses of these components are applications where the desired flow or cylinders speed is known in advance and following adjustments are not required. The advantages of using throttle fittings is the impossibility of making unwanted adjustments to the flow and the constancy over time of the adjustment, which is essential in the presence of vibrations.
