CRYOGENIC

Product choice cryogenic changeover valve

In contrast to a standard ball valve on a changeover valve at least two safety valves are designed to protect the application (for example, a liquid gas tank) against impermissible overpressure.
A changeover valve has usually two outputs but one input only and serves to connect two safety valves with a pressure device. Changeover valves can be found in the area of air gases, vapours and in cryogenics at cryogenic liquefied gases such as Nitrogen. Cange-over valves are available in sizes from DN6 to DN50 and secure pressures up to 250 bar, at operating temperatures of + 400°C to -270°C. The changeover valves are manufactured primarily in stainless steel but also in bronze and brass.

Please find the change-over valves in the product choice below. You can combine different product characteristicsto find your cryogenic changeover valve better.
