Valves in Monel® 400, K500 and A494 M35-1 valves and their use.
Monel® is an excellent trim material for aluminium-bronze body valves for seawater service. Monel® is also highly suitable for oxygen service, and is highly resistant to corrosion, hence its use in alkylation processes in contact with HF acid for Phillips' 2007 specification for alkylation plants as well as UOP specs.
