Pressure regulation valve for regulating hydraulic pressure at working connection of value between low pressure and high pressure, comprises high pressure seat valve, which is arranged in housing

摘要

The pressure regulation valve (1) comprises a high pressure seat valve (17), which is arranged in a housing (20), and a low pressure seat valve (19), which is movably retained in a control piston (13). The high pressure and low pressure seat valves are coaxially aligned to each other for mechanical actuation.
