Control valve having independently driven valves |
摘要 |
The control valve has a quick-acting main valve and a safety valve which are independently operated either by a working medium which is being controlled or by an auxiliary pressure medium. The control for the valves includes a number of control elements which allow a pressure medium to be delivered to selected chambers of the two valves while venting other chambers.
