PNEUMAX – PILOT SPRING VALVE TYPE 212/2.52.11.1

The series 200 consist of a broad range of valves with various type of actuation.
The connections for this series are from G 1/8″ to G 1″ Due to their special construction with a balanced spool, these valves can be used interchangeably as 3 ways or 5 ways a can be seen in the functional schemativs in section 0.
This is important because, for example, the 3 ways can be used normally closed or normally open and the 5 ways can be fed through the exhausts 3 and 5 with different pressures according to the need. The spool, as it is moving, isolates the connections with out being effected by the inlet pressure.
