The RT03A410 is a pressure control valve produced by Vickers within the Pressure Control Valves series. It regulates hydraulic line pressure to keep automated machinery within defined limits. Hydraulic actuation lets the valve shift using the fluid’s own energy, eliminating external pilot power. A maximum operating pressure rating of 3000 psi establishes the upper boundary the device can safely manage in closed-loop circuits. Compatibility with hydraulic oil supports reliable sealing and minimizes internal wear during continuous duty. The ISO 4401-03 (NFPA D03) interface and system stack mounting style enable direct sandwich installation between adjacent manifold plates.
The valve accommodates a flow rate up to 12 gpm so mid-size cylinders and motors receive adequate supply without excessive pressure drop. A maximum temperature limit of 155 °F permits use in power units where fluid warms during sustained duty cycles. The cast iron body resists fatigue and abrasion, extending service life in demanding industrial environments. Overall height of 178.6 mm helps stack designers maintain uniform tier spacing, while a length of 70.9 mm and width of 69.8 mm keep the footprint compact. A 3/8 NPT port size aligns with common pipe threads to simplify connection to inlet and return lines. These physical and thermal characteristics combine to make the valve suitable for medium-capacity hydraulic manifolds where space, durability, and consistent flow control are required.
