Burkert 20070294 Type 0330 is a direct-acting, media-separated pivoted armature solenoid valve. This specific explosion-proof variant features a 3/2-way distributing circuit function (CF F), a stainless steel body, and an EPDM seal. The solenoid coils are moulded with a chemically resistant epoxy, and the coil system is separated from the medium by a diaphragm, making it highly suitable for critical and aggressive media. It operates at 24 V and is certified for ATEX and IECEx hazardous locations.

Explosion Risk

The solenoid valve forms a closed system after installation. When used in explosion-risk areas, there is a risk of explosion if the system is opened in the operating state. Do not remove or open the system during operation.

Electrostatic Discharge

There is a risk of explosion in potentially explosive areas if there is a sudden discharge of electrostatically charged devices or individuals. Take appropriate measures to ensure that no electrostatic discharges can build up in the potentially explosive area.
