1. Introduction

The D*1*W*EE with explosion proof solenoids are

based on the standard D*1*W series. The specif-

ic 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 oper-

ating 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. Direction-

al valves with an integral check valve are available

for the series D31NW and D41VW.
