Why Monel 400 for Gate Valves?

Monel 400 gate valves combine the gate valve's proven shutoff design with the industry-standard material for hydrofluoric acid alkylation and one of the best choices for high-velocity seawater. This makes them the standard specification for hydrofluoric acid, seawater, brine, caustic soda, and salt production media.

Supreme Valves manufactures monel 400 gate valves in ASTM A494 M35-1 / B564 N04400 with design and testing per API 600 / API 603 / BS 1414. Every valve ships with EN 10204 3.1 material certificates and full pressure test reports; third-party inspection by Lloyd's, BV, or TÜV is available for project orders.
