Why Inconel 625 for Gate Valves?

Inconel 625 gate valves combine the gate valve's proven shutoff design with retains strength and oxidation resistance to 650°C while resisting chloride pitting and sour gas cracking. This makes them the standard specification for high-temperature process gas, sour hydrocarbons per NACE MR0175, molten salt loops, and superheated steam.

Supreme Valves manufactures inconel 625 gate valves in ASTM A494 CW-6MC / B564 N06625 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.
