ASCO 266 Solenoid Valves – Fuel Oil Direct Acting Solenoid Valve 2 Way NC NO

ASCO 266 hot water solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel..

ASCO 266 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 266 solenoid valves are part of the ASCO Red Hat range of valves.

ASCO 266 solenoid valves are general purpose enclosures featuring 2 way normally closed or normally open operation.

The valves are suitable for on-off control of fuel oil in commercial and industrial burners as well as being suitable for both light and heavy oil fuels.

Typical industries and applications include combustion within oil and gas and other industries.

Fluids suitable for use with ASCO 266 Solenoid Valves include:

  • No. 2 Fuel Oil at 60 SSU
  • No. 4 Fuel Oil at 300 SSU
  • No. 5 Fuel Oil at 5000 SSU
  • No. 6 Fuel Oil at 5000 SSU (Heated)
