Frequently Asked Questions - Marine Valves

What class society approvals do your marine valves carry?+
Our valves are available with DNV GL, Lloyd's Register (LR), ABS, BV, and RINA class certificates. Type approval and individual test certificates are provided with each delivery.
Which material is best for seawater service?+
Super Duplex 2507 (A890-5A) is the preferred material for fully submerged seawater service and high-velocity flow. Duplex 2205 and naval brass (C83600) are used for non-submerged and low-velocity seawater applications.
