  • Flange connections DN 25

Dival 500 is a downstream direct acting, low, medium and high pressure regulator. It is used for filtered, non-corrosive gases and liquefied gases. Due to its balanced plug design, it offers a high pressure control accuracy and a reduced response time.

The high modularisation degree allows the adding of alternative devices and fixtures (shut-off valve, relief valve), as well as including the line monitor function (auxiliary regulator).

Technical specifications:

  • Maximum inlet pressure: 10 bar BP version / 20 bar MP and TR versions
  • Downstream pressure range: 15 2500 mbar
  • Accuracy class: up to 5% from the controlled pressure
  • Ambient temperature: -20C +60C
  • Inlet/outlet threaded connections: DN 1" + DN 1" or DN 1" + DN 1 1/2"

Dival 600 is a downstream direct acting, low and medium pressure regulator. Its modular design allows the adding of auxiliary devices (slam-shut valve, relief valve, noise damper, monitor function adapter).

The extremely short response time make Dival 600 suitable for use in burner plants, industrial plants etc., where large flow variations may occur.

Technical specifications:

  • Design pressure: 20 bar
  • Maximum inlet pressure: 20 bar
  • Downstream pressure range:
    • DN 25:     12 340 mbar BP/MP versions; 300 4200 mbar TR version
    • DN 40-50: 12 85 mbar BP version; 80 340 mbar MP version; 300 4200 mbar TR version
  • Accuracy class: up to 5% from the controlled pressure
  • Ambient temperature: -20C +60C
  • Threaded connections: DN 2" / Flanges: DN 25, DN 40, DN 50

The HP100 - HP100/B series include self-driven, direct acting, balanced plug, diaphragm controlled and counter spring regulators, for medium and high pressure.

They are designed for use in natural gas/LPG distribution plants (non-corrosive gases), which require a high control accuracy and a short response time to flow variations.

Very suitable as 1st stage pressure regulators in home and industrial plants.

Technical specifications:

  • Design pressure: 20 bar
  • Inlet pressure: 1 20 bar
  • Downstream pressure range: 200 800 mbar AP version; 800 4500 mbar TR version
  • Accuracy class: up to 5% from the controlled pressure
  • Ambient temperature: -20C +60C
  • Threaded connections - various sizes and flange adapters

The NORVAL series regulators are direct acting, diaphragm controlled and counter spring regulators, for medium and low pressure.

To be used in distribution plants for non-corrosive, previously filtered gazes.

They feature by extreme quick response to the changes of the operating conditions, thus being especially suitable for ON-OFF burner plants and other industrial processes in which rapid flow fluctuations occur.

Technical specifications:

  • Design pressure: 19 bar max.
  • Inlet pressure:
    • DN 1" 3": 0,1 19,6 bar
    • DN > 3":     0,1 8 bar
  • Downstream pressure range:
    • DN 1" 4": 8 4400 mbar
    • DN 6" 8": 12 1800 mbar
  • Accuracy class: up to 5% from the controlled pressure
  • Ambient temperature: -20C +60C
  • Flange connections: 25 (1"); 40 (1"1/2); 50 (2"); 65 (2"1/2); 80 (3"); 100 (4"); 150 (6"); 200 (8")

The TRIAS/BM - TRIAS/BB series regulators are direct acting, diaphragm controlled and counter spring regulators, for medium and low pressure.

To be used in distribution plants for non-corrosive, previously filtered gazes.

They have been designed in a manner that allows mounting three different devices on a single body:

TRIAS/BM (fig. 1):

  • Monitor emergency regulator
  • Monitor emergency regulator
  • Slam-shut valve

TRIAS/BB (fig. 2):

  • Main regulator
  • 2 Slam-shut valves

These devices require selfstanding closing parts and tightening surfaces, thus making it possible to reduce the overall dimensions, but also keeping the required safety devices.

Technical specifications:

  • Design pressure: 19,2 bar
  • Maximum inlet pressure: 8 bar
  • Downstream pressure range: 20 4000 mbar
  • Accuracy class: up to 5% from the controlled pressure
  • Ambient temperatur e: -20C +60C
  • Flange connections 1"1/2 and 2"

To be used in civil and industrial installations for natural gas, LPG, or other non-corrosive gases (dry gases).

COMPACT versions (FRG/2MBC, FRG/2MCC, RG/2MCC) are suitable for small consumers.

The regulators may be equipped with the following safety devices and accessories:
  • inlet filter
  • downstream over-pressure shut off device
  • relief valve
  • downstream low pressure shut off device
  • outlet pressure test point
