100% TESTED, with modern 100% helium plant, each valve bears the date and serial number proving that it has passed the test and allowing traceability of the performance data measured during testing over time

The solenoid expansion valve in the series 44000 are designed to be installed on refrigeration and air-conditioning system for domestic and industrial use. It’s possible to use them with all the refrigerant fluids of goup 2 of Art.13, Chapter 1, point A or B, of Euopean Directive 2014/68/EU, with reference to EC Regulation no. 1272/2008. Some typical applications are:

  • Refrigeration (refrigerated counters, supermarket displays, machines for making ice or ice cream)
  • Air conditioning systems 
  • Chiller
  • Heat pumps

The main components of the solenoid expansion valves in the series 44000 are: 

  • Brass body made of EN12165 CW617N 
  • AISI 303 stainless steel sleeve
  • AISI 303 stainless steel sealing insert
  • PTFE sealing gasket
  • Neoprene sealing O-ring (HNBR option for flammable fluids)
  • Ferromagnetic steel cores
  • AISI 303 stainless steel filter
  • AISI 302 stainless steel springs
  • Class H coils complete with moisture-proof seals
  • Copper pipes to UNI-EN12735/1-Cu-DHP

Before installing the expansion valve, make sure the refrigeration system is properly clean, though any impurities are intercepted by the filter mounted inside it. An excessive amount of impurities could partially of fully clog the filter, thus reducing its overall performance. The expansion valve can be mounted in all positions, though it is preferable to keep the axis at a right angle with the coil at the top. The direction of the arrow stamped on the valve body must coincide with the direction of flow of the fluid inside the system. Braze welding between the copper pipes and the valve body is performed using low-temperature melting alloys and the presence of seals requires the fitter to pay particular attention in avoiding to direct the flame towards the valve body and sealing areas in general.
