1. Introduction
The D*1*W*EE with explosion proof solenoids are
based on the standard D*1*W series. The specific solenoid design allows the usage in hazardous
environments.
The explosion proof class is
Ex mbe II T4 Gb
for use in zone 1 (conform to ATEX).
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 mini-
mum pilot pressure must be ensured for all operating conditions of the directional valve.
Additionally spools with a P to T connection in the
de-energized position need an external pressure
supply (external inlet) or an integral check valve.

Integral check valve in the P port
Mounting an integral check valve in the P port is
necessary to build up pilot pressure for valves with
P to T connection and internal pilot oil supply. The
pressure difference at the integral check valve
(see performance curves) is to be added to all flow
curves of the P-port of the main valve. Directional valves with an integral check valve are available
for the series D31NW and D41VW.
