Butterfly valves

Reliable intelligent emergency shutdown (ESD) valves and actuators with Neles™ ValvGuard™ intelligent valve controllers improve your plant safety cost efficiently. In Neles we have combined our know-how of valves, actuators, safety standards (IEC61508/61511), applications, system operability and partial stroke test devices with intelligent prediction tools. Diagnostic information is presented understandably to enable planned maintenance of potentially failing valve assemblies before they have a chance to impact the process or safety.

Neles BWX series high performance butterfly valve has been especially designed for use in cryogenic applications with high quality CrNi steel. Testing of the valve includes cold shock test and it can be used for gaseous and liquid oxygen, LNG, nitrogen, hydrogen and other cryogenic fluids.
