OPTION: EXPLOSION-PROOF SOLENOIDS II 2 G EEX DM IIC T4
Explosionproof solenoids with flameproof enclosure/encapsulation “dm”
According to ATEX directive 94/9/EC and Standards EN 50014, EN 50018, EN 50028 and EN 50281-1-1.
Application:
Control of solenoid valves intended for installations in hazardous areas in which explosive gas-atmospheres are present, i.e.
zones 1 or zones 2 (ATEX: Group II, apparatus categories 2G or 3G).
The enclosure of these explosion proofs solenoids "dm" is made entirely in synthetic material. All external metallic
components in contact with the atmosphere are made in stainless steel. The integrated sealing and O-rings assure the
degree of protection IP67. Therefore, these products took into account not only the suitability with hazardous areas but also
extremely corrosive environment, e. g. Chemical, Petrochemical and Refineries industries (CPR). Due to the compact size
and easy cable connection by screw terminals, these solenoids may be mounted in confined spaces.
Features:
The coil winding (copper wires of insulation Class H) and magnetic iron path are encapsulated in synthetic material Class H
and meet "m" protection. The connection box and cover of selected high quality synthetic material (Class H) in order to meet
the standard EN 50018 for type of protection "d" flameproof enclosure.
The cable gland assembly M20x1.5 makes part of
the "d" certificated enclosure.
The solenoids are provided with an embedded non-resetting thermal fuse to prevent
excessive heating, i.e. assuring the maximum allowed surface temperatures T5/T4. A varistor for peak voltages suppression
is potted-in, in Epoxy resin Class H.
