D*W*EE Series Pilot Operated Directional Control Valve, Explosion Proof
Key Features
The D*1*W*EE with explosion proof solenoids is based on the standard D*1*W series. The specific solenoid design allows the usage in hazardous environments.
The explosion proof class is Ex e mb II T4 Gb for use in zone 1 and 2 (conform to ATEX). Additionally the solenoids have IECEx conformity.
All explosion proof solenoids are DC design. The valves for AC operate with integrated rectifier. The pilot operated valves are available in 4 sizes:
- D31DW NG10 (standard)
- D31NW NG10 (high flow)
- D41VW NG16
- D91VW NG25 (for port diameter up to 32 mm)
- D111VW NG32
All valves are piloted by a D1VW valve. The minimum pilot pressure must be ensured for all operating conditions of the directional valve.
Additionally spools with a P to T connection in the deenergized position need an external pressure supply (external inlet) or an integral check valve.
