The CVU40EFP1B299031 is a hydraulic cartridge valve from Vickers within the Cartridge Valves series, intended to meter or block flow in automated power units and manifolds. It fits an ISO 7368 cavity size 10 (NG40), allowing direct installation in standard sandwich blocks. Ports A, B, and X withstand up to 315 bar (4500 psi), so the valve can operate in high-pressure circuits, while the dedicated Y drain line is limited to 2 bar (29 psi) to protect the pilot section. At a 10-bar differential the valve passes 900 L/min, supporting large actuator speeds. The solenoid coil shows 2.8 Ω resistance at 20 °C and draws a maximum of 2.9 A at 50 °C, parameters that guide power-supply sizing. A continuous duty rating of 100 % ED keeps the valve energized without thermal cycling, and an IP65 enclosure guards the coil against dust and water jets in industrial environments.
Flow control repeatability is maintained within ±0.5 %, providing consistent positioning when the valve is used for precise motion tasks. The poppet opens from A to B once pressure reaches 2.5 bar (36 psi) and permits reverse flow only after 6.5 bar (94 psi), figures that define its check behavior in bidirectional systems. Dynamic performance includes opening and closing step responses of 125 ms each, enabling moderately fast cycle times. Mechanical attachment relies on four M20 × 70 mounting bolts that secure the cartridge against shock loads, and G-threaded plugs conforming to ISO 228/1 are fitted for service ports. The assembly weighs 8.0 kg (17.7 lb), a factor to consider when selecting handling methods during maintenance.
