Archivio Istituzionale della RicercaThe paper investigates the friction forces developed between the sliding members of a proportional pressure regulator with a power stage consisting of a poppet-type pressure reducer driven by a piston, and a pilot stage with two MATRIX high frequency digital monostable 2-way valves controlled by the PWM technique. Carried out using a specially developed test bench, the investigation identified lubricants and seal geometries that minimize friction forces. Effects of different greases and seal geometries were evaluated and different solutions were compared.

Abstract
The paper investigates the friction forces developed between the sliding members of a proportional pressure regulator with a power stage consisting of a poppet-type pressure reducer driven by a piston, and a pilot stage with two MATRIX high frequency digital monostable 2-way valves controlled by the PWM technique. Carried out using a specially developed test bench, the investigation identified lubricants and seal geometries that minimize friction forces. Effects of different greases and seal geometries were evaluated and different solutions were compared.
