Pressure / Flow Switch Code 4900

The Conflow Code 4900 - Pressure/Flow Switch ensures electrical circuits only operate when minimum fluid pressure and flow requirements are satisfied.

The unit uses the same principle as the Code 240 flow switch, but with an additional hydraulic pressure latch, which interrupts the flow if the system pressure does not rise above the required minimum value.

Even if the flow is above the required value the electrical switch does not make unless there is sufficient system pressure to lift the pressure latch and allow flow back into the main line.

The advantage of this unit is its compact size and its need to use only one electrical switch, giving distinct benefit when cabling up into machine circuitry and subsequent fault finding.

Typical Applications

  • To interrupt pilot electrical circuits on coal cutting machines if the minimum requirements for water flow and pressure on ITP systems are not met
