Dome loaded pressure controller

Very proven dome loaded pressure controller LTD-1 with the following special features:

  • For almost all technical gases, air and liquids
  • Broad performance spectrum: 10 … 2,500 m3/h
  • Wide working pressure range:
    • inlet pressures 0.5 … 100 bar
    • Back pressures 0.1 … 70 bar
  • No “flutter”, even with large inlet pressure fluctuations
  • Back pressure control independent of the inlet pressure
  • Flexible operation:
    • locally with own or external medium
    • remote controlled via pilot controller
  • Safety function: spring force closing = “positive sealing

If the particularly even outlet pressure is important, dome pressure regulators show their strengths. In contrast to the simple pressure regulator with steel springs, the dome pressure regulator uses a compressible gas (internal or external medium). This gas pressure accumulator achieves a sensitive response without self-damping and without spring characteristic curve.
This is why LT dome pressure regulators have a extra large cathedral chamber.
