RCT-10-D1 11

The RCT-10-D1 11 valve belongs to the Pressure Control Valves series produced by Vickers for use in hydraulic automation where stable system pressure is mandatory. It employs pilot operated actuation so a small control flow modulates the main stage and reduces response effort in high-flow circuits. A two stage configuration further isolates the sensing element from line shocks to improve pressure stability during rapid load changes. Size 10 dimensions suit medium to large manifold layouts, and the 1 1⁄4 in NPT pipe mount simplifies direct installation on return or pressure lines without adapter blocks. The single port size of 1-1/4 NPT provides adequate area for the rated capacity while keeping connection standards familiar to maintenance staff. An internal drain path returns pilot flow to the inlet side, removing the need for an external hose. A built-in check valve allows reverse free flow, protecting upstream components during pressure decay or pump stoppage.

The adjustable spring stack sets outlet pressure between 17.2 and 70 bar (250–1000 psi), letting operators match system demands without changing hardware. When inlet pressure reaches the chosen setting, the unit can withstand up to 210 bar (3000 psi) without structural damage, covering typical mobile and industrial circuits. Flow passages accommodate 284 L/min (75.0 US gpm), so a single valve manages high displacement pumps without excessive velocity loss. Petroleum-based oils are recommended as the working medium, and the cleanliness code of 19/17/14 limits particulate contamination to levels that prevent spool wear. Nitrile seals maintain elasticity with these fluids while containing leakage. Continuous service is permitted from –20 °C (–4 °F) to 70 °C (158 °F), making the device suitable for unheated outdoor equipment and warm plant rooms. Because the valve’s type is dedicated to pressure regulation, it relieves excess pump output and maintains consistent actuator loads within the stated flow, pressure, and temperature limits.
