The XT063F23UB valve belongs to the Pressure Reducing Valves series from Vickers and is intended to hold a steady downstream pressure in hydraulic automation systems. It is built to nominal size 06 (3/4 in), giving the flow capacity required for medium-duty circuits. A G3/4 BSPF main port thread connects directly to common manifold or line fittings. The design tolerates inlet pressure up to 210 bar (3000 psi), letting it sit upstream of high-pressure pumps. Its regulating mechanism can deliver outlet pressures between 13.8 bar (200 psi) and 200 bar (2850 psi), providing a broad adjustment span for cylinders or motors with lower ratings. Stable regulation requires at least a 10 bar (150 psi) difference between inlet and outlet, preventing chatter when flow demand changes.
The valve body weighs 5.6 kg (12.3 lb) and measures 176.530 mm high, 162.052 mm long, and 95.250 mm wide, so it fits compact power units without special lifting gear. Mounting attitude is unrestricted, allowing horizontal or vertical installation. All ports share the G BSPF form defined by ISO 228-1, simplifying plumbing with standard pipe threads. The drain port uses a G1/4 BSPF connection and must see no more than 1.7 bar (25 psi), letting excess oil return safely to tank. A second G1/4 BSPF gauge port sits near the outlet, giving technicians a place to read the controlled pressure. Remote pressure adjustment is possible through a G3/8 BSPF pilot port that links to an external control valve.
