Proportional 3-way flow control cartridge  explosion proof Ex d II C QDBPM22

Proportional throttle valves, proportional flow control valves M22x1,5

For explosion-hazard zones
Direct operated, pressure compensated proportional  flow control valve, as a screw-in cartridge with a thread M22 x 1,5 for cavity acc. to ISO 7789. A special surface treatment guarantees a good protection against corrosion and wear as well as very good low-friction characteristics of the pressure compensating- and throttle spool. The solenoid coil is zinc- / nickel-coated.
The flameproof enclosures prevents an explosion in the interior from getting outside.
The design prevents a surface temperature capable of igniting.

Application

Proportional flow control valves are suitable for feed control systems, where the consumer flow has to be maintained constant with a changing load. These valves are suitable for applications in explosion-hazard zones, open cast and also in mines. The facility for electric remote controlling of the valve in conjunction with process control systems enables economic problem solutions with repeatable sequences.
