The CVCS40ZD1S210 cartridge valve belongs to the Cartridge Valves series and is manufactured by Vickers for hydraulic automation circuits that require a compact, insert-style flow regulator. It fits an NG40 cavity that follows ISO 7368 size 10, and its internal area ratio of 1 : 0.05 : 0.30 : 1.35 establishes the pressure balance across the spool lands. A 14.50 mm (0.571 in) stroke provides the necessary travel to uncover the ports fully. When the pressure drop is 5 bar, the cartridge can pass 1200 L/min (317 US gpm) from port A to port B, while reverse flow from B to A is limited to 1040 L/min (275 US gpm). The assembly is rated for a maximum operating pressure of 350 bar (5000 psi), allowing it to function in high-pressure power units and manifolds.
The permitted fluid temperature spans from −20 °C to 70 °C so the valve can work in cold starts and warm running conditions without seal degradation. Mounting requires five 3/4-10 UNC bolts tightened to 370 lbf·ft (500 Nm) to resist hydraulic loads. Pilot actuation hardware is secured by inch threads size 03 and aligns with the ISO 4401 size 03 (D03) interface provided on the pilot cover. Service points use SAE plugs with UNF orifices; the Ap orifice is threaded 1/4-28 UNF-3B to a depth of 8.0 mm, and the Z2 orifice is threaded 3/4-24 UNF-2B to a depth of 11.0 mm. Inch O-rings produced to ISO 3601 standards seal the cartridge, preventing leakage under the stated pressure and temperature limits.
