The RT10D430 belongs to the Pressure Control Valves series and is produced by Vickers for hydraulic automation systems that require accurate pressure regulation. It uses pilot operation, so a small control flow modulates the main flow path for consistent pressure control under varying loads. The unit follows a two-stage layout, with the pilot section triggering the main stage to improve response stability at higher flow rates. Size 10 categorization fixes the internal orifice dimensions and aligns the valve with corresponding circuit capacity. Pressure setting is adjusted through a screw with a locknut, allowing secure field tuning without unintended drift. An internal drain routes pilot flow back to tank internally, reducing external plumbing requirements. Nitrile seals protect interfaces and maintain oil tightness when petroleum-based hydraulic fluid is used, and a cleanliness level of 19/17/14 is required to limit wear and maintain control accuracy.
The valve tolerates system pressures up to 210 bar, defining the maximum regulated outlet level. Flow capacity reaches 284 L/min, permitting use in medium to high flow circuits without excessive pressure drop. Connection is made through a 1-1/4 in NPT pipe mount, so it threads directly into standard pipe runs. Overall dimensions measure 282.194 mm in height, 117.602 mm in length, and 107.950 mm in width, data that guides layout planning inside a cabinet or power unit. Continuous service is allowed with fluid temperatures up to 70 °C, ensuring seal life and stable operation when reservoirs are properly cooled.
