      Frequently Asked Questions

      What is the pressure rating of Inconel 625 ball valves?

      Inconel 625 ball valves come in 3000 PSI and 6000 PSI classes of pressure with sizes between 1/4 inch NPS up to 2 inch NPS. The 6000 PSI is preserved between the cryogenic temperatures (below minus 196 degrees Celsius) and the operating temperatures of about 400 degrees Celsius. A small derating is used at higher temperatures as indicated in the above table of pressure vs temperature.

      Can Inconel 625 valves be used in seawater?

      Yes. UNS N06625 is very resistant to seawater corrosion, and to pitting caused by chloride so it can be used in offshore and marine valves. A very common application of inconel 625 ball and check valves is in seawater injection systems, cooling water headers, and subsea chemical injection where the more common 316L or duplex stainless steel valves suffer rapid corrosion.

      How is a 2-valve and a 5-valve manifold different in Inconel 625?

      A 2-valve manifold is used to offer isolation and equalisation to single-sided measurement of differential pressure. A 3-valve manifold includes block, block and equalise capability. A 5-valve manifold offers dual block and bleed isolation to differential pressure transmitters to ensure it is safe to remove transmitters without shutting down the process. All Kalpataru Inconel 625 manifold valves are designed to 6000 PSI and are produced of ASTM B564 UNS N06625 forged bar stock.
