The annular flow cross-section prevents vibration and allows a linear ratio of flow variation to the valve opening percentage. Linear movement of the plunger in a forward direction causes a reduction of flow rate and at the end position closes the valve with complete tightness by positioning the piston profile sealing ring on the seat ring.
