CombiPressure-Regulator Type 4182
Now available made from bronze
Until today, the regulator was only made of stainless steel, now it is being manufactured from bronze which extends its field of application by, e. g. oxygen application. When extracting the product, the combined or pressure build-up regulator should keep the tank at a pre-set tank pressure. For the pressure build-up function, the HEROSE CombiPressureregulator is also equipped with a pressure reduction/pressure relief function as well as a safety function.
Application:
All tank vessels for cryogenic liquefied gases (operating temperatures from – 196° to + 60° C)
Customer benefit:
- Increase in safety and significantly less effort for repairs due to less downtimes
- Now also suitable for oxygen applications
Development engineer Philip Boldt:
"An important factor during the development was the close coordination with our casting supplier" Moreover, the bellows also had to be modified."
Diverter-Plug-Valve Type 7111
Replacement during running operation
The Diverter-Plug-Valve allows safety valves to be replaced or maintained, also during operation of the pressure vessel. The valve, a so-called plug valve is used ideally on upright tanks for cryogenic liquefied air gases as maintenance fitting for the assembly of safety valves and bursting disks. This combination protects the vessel against an excessive increase of pressure.
Application:
For upright tanks for the storage of cryogenic liquefied gases (operating temperatures from – 196° to + 120°C ).
Customer benefit:
- higher volumetric flow
- compact design, less space requirement and a low weight
- overhauling of the safety valves during running operation
- increased safety during maintenance work on the safety valve due to the plug design
Development engineer Daniel Scharr:
"Despite the small design, the valve permits a high volumetric flow. The optimisation has been achieved in particular by means of the CFD simulation methodic.“
Top-Entry-Valve Type 01420
Series expansion to DN 100
Until now, the Top-Entry-Valve was available in nominal diameters DN 15 to DN 50. Now the series has been expanded to the nominal diameters of DN 65, DN 80 and DN 100. With a Top- Entry-Valve, the complete top part can be pulled out of the fitting upwards.
Application:
Air separation plants and double-walled piping systems with insulation, air gases, vapours and cryogenic gases (operating temperatures from – 196° to + 120° C)
Customer benefit:
- During the maintenance of the cone or top section, the insulation is not damaged as the bolts of the head piece are located outside the insulation. As a result, the customer has a saving in material, costs and time
Development engineer Claudia Rentzow-Homm:
"With its height of around about one metre, a valve with nominal diameter DN100 is already a challenge."
