1.0 - GENERAL INFORMATION

The instructions for use ALWAYS need to be available in the facility where the device is installed.
ATTENTION: installation/wiring/maintenance need to be carried out by qualified staff (as explained
in section 1.3) using appropriate personal protective equipment (PPE).

1.1 - DESCRIPTION
Automatic solenoid valve (it opens when under tension and closes without) suitable to detect fuel oil.
The MN28 series solenoid valve is conceived to be very reliable even in the hardest working conditions. It has a large section
of passage and so a low load loss.
Its construction is very good with a die-cast aluminium structure, Viton sealing parts and all parts in direct contact with fluid,
made of brass and stainless steel. The solenoid valve is open only when powered.
If compared to other membrane servo-controlled or apparently similar models, the MN28 solenoid valves can work non-stop
even in loop circuits with upstream and downstream pressure differential from 0 to 8 bar.
The opening and closing rapidity permits use of MADAS solenoid valves where a precise fluid dosage is needed.
