Parker Conflow’s Code 5042 is a highly effective Intrinsically Safe water flow switching device for use underground in dust suppression applications.

Certified as being Instrinsically Safe (IS) for underground use in explosive atmospheres, this pilot-operated valve can be used with pressures up to 100 bar. It consists of two halves – valve (wet end) and solenoid.

The valve is a pilot operated stop-valve, which requires only a small force to open fully. The solenoid half is an electrical coil (driver) which, when energised, causes a mild steel core to move axially within the coil. This movement exerts a force in excess of that required to operate the pilot valve in the wet end.

It is available in 1/2", 3/4", 1" & 2” versions and controls flows up to 180 GPM.

Operated by a 12V DC supply, the device has been designed to operate with an intrinsically safe low energy supply suitable for underground use.

Markets:
• Quarrying
• Mining

Features/Benefits:
• Rapid shut off time provides efficient use of water.
• Safety – operated by a 12V DC supply - uses low voltage unit for operating underground.

Applications:
• Controlling belt sprays.
• Dust suppression on the cutting heads in mines.
• Control of water cooling to trunk conveyor belt drives.
