CVCS-25-C1-S2-W-350-11

The CVCS-25-C1-S2-W-350-11 pressure control cartridge valve is produced by Vickers within the Cartridge Valves series and is intended to limit hydraulic system pressure in automated manifolds. The unit follows the ISO 7368 B-**-2-A interface so it fits standardized NG25 cavities during assembly. Its nominal size is 08 (NG25), defining passage dimensions suited to mid-frame circuit blocks. The adjustable pressure span starts at 8 bar (116 psi) and rises to 350 bar (5000 psi), allowing technicians to set relief thresholds for diverse machinery. Maximum operating pressure is 350 bar (5000 psi), matching the upper adjustment limit to safeguard internal parts. Pressure is trimmed with a wrench and hex locknut adjuster that secures the setting against vibration. Performance figures reference an oil viscosity of 36 cSt (168 SUS) to ensure consistent calibration.

Flow capability is sized for 590 L/min (155 USgpm) as the recommended maximum so the valve can protect high-capacity pumps without excessive pressure loss across the cartridge. When a main flow of 550 L/min is present, the pilot stage draws only 1.70 L/min, which keeps pilot lines small and reduces heat generation in the control loop. Mechanical fastening relies on M12 × 40 mounting bolts; each bolt is tightened to 110 Nm (81 lbf·ft) to maintain gasket compression and resist dynamic loading. This bolt specification permits straightforward service with common torque tools while protecting manifold threads. The cartridge weighs 2.9 kg (6.40 lb), a mass that supports manual handling during installation and eases replacement in confined equipment bays.
