D81VW009C2NJW Indirectly controlled hydraulic slide valve PARKER, NG25

PARKER hydraulic indirectly controlled switchboard with emergency control.
All valves are controlled by valve D1VW. See separate ordering code for position controlled valves. The minimum control pressure must be ensured for all operating conditions of the switchgear. In addition, coils with a P to T connection in the de-energized position need an external pressure source (external input) or an integrated non-return valve for pressure control of the valve.
