Check valves

The benchmark for check valves 
As for high-pressure valves, the high-pressure check valves range complies with SAE 3000 & 6000 (ISO standard 6162-1 & ISO 6162-2). The SAE check valve allows assembly between flanges or flanged against a block (smooth or tapped holes). It is also possible to adapt the tapping to the needs of different hydraulic systems.
