Two=way positional control valve - has two sets of logic valves with control edge positive overlapping in one set only

摘要

The seat valve has a pressure connection (P), a tank connection (T), a first user connection (A) and a second user connection (B). The unit has a pre-control valve (14) and four controllable 2/2 way logic valves (10,11,12,13). In two of the logic valves (10,11) the closure element in the closed position positively overlaps the control edge of an opening. In the other two logic valves (12,13) no positive overlapping is present. USE/ADVANTAGE - Two-way positional control valve allows the optimal adjustment of the logic valve nozzles and minimises viscosity-dependency effects on the action of the valve.
