The 3CA300-1.0-S valve belongs to the Directional Control Valves series manufactured by Vickers for hydraulic automation that relies on cartridge components. It mounts as a screw-in cartridge, allowing compact manifold layouts, and fits the A13245 cavity so installers can use standardized machining. A tightening torque of 150 Nm seats the body against the cavity shoulder to secure the seal. The valve measures 72.390 mm long and 45.999 mm wide, dimensions that let it fit densely packed blocks. Two ports are provided because this direct-acting design switches flow between an inlet and an outlet without pilot assistance. The cartridge-only port style limits external plumbing, while the ball style seats the element firmly for consistent shut-off.
A maximum working pressure of 350 bar lets the unit operate in high-pressure circuits common in mobile and industrial machinery. The 300 L/min flow rating defines the highest volume it can pass without excessive pressure drop, and a cracking pressure of 1 bar sets the point where the ball lifts to start flow. Internal leakage is limited to 0.2 cc/min, conserving energy by reducing bypass losses. A filtration level of 18/13 is recommended to keep contaminants from damaging the seating surfaces, and Buna-N seals are used for compatibility with mineral oils typically found in power units. There is no pilot piston seal, which simplifies the internal layout and eases maintenance.
