ABSTRACT:
A proportional flow valve wherein inlet fluid pressure urges a main valve member toward a valve seat. A cylindrical bearing ring is mounted on the main valve member and slideable within an axial bore leading from the main valve seat to an outlet port for axially stabilizing the main valve member and limiting pressure differential across the main valve member while the bearing ring is at least partially disposed within the axial bore. The outer circumference of the bearing ring may have circumferential grooves for producing eddy currents and turbulence to enhance the limitation of pressure differential across the main valve member.
