AXIUS 1400 PNEUMATIC CRYOGENIC BELLOWS VALVES

The Axius 1400 pneumatic cryogenic bellows valve is a straight-through valve designed for low or high pressure applications. It is designed to be a compact and space-saving unit, with integrated axial bellows actuator with stainless steel body for gaseous or liquefied media in cryogenic systems.

It offers quick closing and opening times (fast shutter speed) and can be installed unrestricted in any position. Its hermetically tight internal tube has stainless steel bellows on both sides offering end users a long service life and high leak-tightness to atmosphere.

End connections can be supplied in standard butt-welded configurations or according to customer specifications. The Axius 1400 is also available for ambient media temperature and as check valve (non-return valve) design. Further PN values are available on request.
