Dome Loaded Pressure Controller Units

The dome loaded pressure regulators LTD-1 and LTD-2 are as well available in various configurations as dome-loaded pressure control unit. The following configurations are offered as standard:

  1. Pressure gauge to indicate the inlet pressure and/or the outlet pressure
  2. Built-in pilot pressure controller, with self-relieving design
  3. Recirculation of the pilot pressure controller additionally with the output pressure

Main advantages

  1. Very precise instantaneous pressure control without ‚wobbling‘ even with large variations in inlet pressure or the required gas quantity
  2. Compensation of e. g. temperature induced pressure changes in the dome chamber by the pilot controller
  3. High stability of the output pressure by the pilot pressure regulator charged with outlet pressure
  4. Easy adjustment by hand wheel, reversibility and direct readability at the gauge with marking pointer
  5. Large volume flows (LTD-1: N2 up to 2.000 Nm³/h, LTD-2: N2 up to 5,000 Nm³/h, depending on pressure conditions)
  6. Short overall length (LTD-1: 127 mm) – esp. compared to pressure control panels with the same function

The pressure control units can as well be delivered in nickel-plated brass or in stainless steel. Control units for higher inlet pressures up to max. 420 barg upon request.

Modular system for LT pressure control units

Each pressure control unit is configured individually. Please name
Gas type, inlet pressure and outlet pressure

Depending on this, the components are selected:

  • Dome pressure regulator LTD-1 or LTD-2 low pressure or medium pressure
  • Elastomers Viton or EPDM
  • Pilot pressure regulator depending on the range to be set
  • Manometer or pressure transmitter with optimum readability of the range to be set
  • Compliance with special regulations (O2, medicine etc.)

Modular system for individual solution with a precise, finished and tested delivery

The following standard types of the LTD-1 dome pressure control unit (based on the 1″ dome loaded pressure regulator) are currently available:

Pressure control unit: Highest outlet pressure stability
especially for fluctuating demands

The following standard types of the LTD-2 dome pressure control unit (based on the 2″ dome loaded pressure regulator) are currently available:
