3CA300--0.3SV

The 3CA300--0.3SV check valve is manufactured by Vickers and belongs to the Check Valves series. Designed for hydraulic automation, it permits free flow in one direction while preventing reverse flow to protect pumps and actuators. The valve uses direct acting operation so the poppet responds directly to line pressure without a pilot stage, reducing response time in high-cycle circuits. It is rated for 350 bar, allowing integration into high-pressure systems. A flow capacity of 300 L/min accommodates large displacement pumps and manifolds. The screw-in cartridge installation type lets the component be threaded into a standardized manifold cavity A13245, saving space compared to line-mounted bodies. Because the port type is cartridge only, all external connections are provided by the manifold passages, simplifying hose routing. Two valve ports handle inlet and outlet flow paths, matching typical manifold channel layouts.

For builders who prefer modular manifolds, the valve offers two housing ports so the cavity can be machined with minimal block length. Internal leakage is limited to 0.2 cc/min, maintaining actuator position without the need for supplementary pilot lines. Reliable sealing is maintained from -20 °C to 90 °C, giving the valve a temperature range suitable for outdoor machinery and factory presses; the minimum temperature supports cold-start operation, while the 90 °C ceiling protects elastomers from thermal degradation. When installed as a cartridge, the compact envelope keeps service access clear and allows stacking of multiple functions in one manifold station. This shutoff capability sustains repeatable performance during rapid cycling, and the low leakage characteristic preserves energy during load-holding operations.
