Advantages of pilot operated check valves
In addition to the important safety function of ensuring the compressive stress in the cylinder, the pilot operated check valve offers another useful function: the lowering speed of a cylinder under load can be precisely adjusted by finely dosed opening of the valve. The pilot operated check valve thus not only fulfils a safety function - it also contributes to improved handling of the hydraulic system. By making the lowering movement of the load more controllable, the weaker components of a hydraulic system are automatically relieved. They thus contribute significantly to extending the service life of hoses and sealings.
