Ampo Poyam Valves (AMPO)

AMPO is a world leader in highly engineered valves for the most severe applications, such as critical cryogenic valves in the temperature range for LNG or liquefied air gases, as well as for liquefied hydrogen or helium.

Microflow control and shutoff valves from DN2, vacuum or non-vacuum isolation applications are part of the valve portfolio. Axial check valves for vacuum and non-vacuum isolations are also available for liquefied hydrogen or helium, as well as top-load ball valves.

Cryogenic He leak and pressure tests in LN2 baths at 77 K are daily business to pursue the main activity with valves that can work in any field above 80 K: ball, gate, check, butterfly, globe valves from DN25 to DN2500 and low pressure up to 2000 bar gas and 3000 bar hydro pressure. Custom solutions are a key part of the company’s focus, including the delivery of integrated smart solutions as turnkey projects.
