Superior pilot-to-open check valves are defined by their leakage. With Sun Hydraulics’ high-calibre design, leakage is at an absolute minimum yet they still maintain a variety of panoptic cracking pressures ranging from 0.3 bar up to 7 bar. Flow capacities range from 30 l / min. up to 480 l / min. All Sun Hydraulics’ pilot operated check valves work on a 3:1 pilot ratio.
