Vickers 0694348 Valve Orifice for Hydraulic System

The Vickers 0694348 Valve Orifice is a precision‑machined DO3 (NG6 / CETOP 3) internal valve insert designed to restrict and meter hydraulic flow inside valve assemblies. It has a 0.090 in. orifice diameter and provides hydraulic flow regulation for directional and control valves, enabling precise circuit tuning in hydraulic power units and industrial machinery. Manufactured by Vickers (Eaton Vickers), part number 0694348 with reference number 314630, it is a common replacement for Vickers 314631 valve orifice and DO3 series inserts. Typical applications include hydraulic power units, machine tools, material handling equipment, and automated production systems in industrial manufacturing and process control, using hydraulic oil and compatible fluids.
