High-Low Direct Dial Pilots for Control Systems

High-Low Direct Dial Pilots for Control SystemsWeatherford’s dial-adjustable pilots offer accurate, reliable operation and feature full stainless steel construction to insure years of dependable operation even in the most severe applications. To further protect each pilot from the elements, every pilot is mounted in a lockable weather-tight fiberglass or 316 SS case. Models are available to sense a wide range of pressures to 10,000 PSI (689.5 BAR). Standard supply and output pressure is 30 PSI (2.1 BAR), with other pressures available.

Weatherford’s high-low direct dial pilots include the following options:

  • Single or dual porting
  • Facility manual reset
  • Indicating pressure gauges
  • Adjustable setting dials
  • Pressure sensing ranges
  • Extreme corrosive applications
  • Various mounting options

Model SDE PilotHigh-Low Direct Dial Pilots for Control Systems

The single pilot SDE model senses either high or low pressure. This pilot is fully instrumented with gauges for sensed and output pressure.

Model SDEP Pilot

This unit is the panel mountable version of the SDE pilot and is supplied without the instrument gauges and fiberglass case. The SDEP model is usually used in a control panel.
