CAST STEEL MARINE GATE VALVES FEATURES / MATERIALS

CAST STEEL BOLTED BONNET

NEWCO marine valves have been specifically designed for high reliability operation in the confined, corrosive atmosphere prevalent in the marine industry. Manufactured and tested under the strict supervision of Newman's, they meet the critical standards demanded by such agencies as the American Bureau of Shipping, U. S. Coast Guard and the U. S. Navy. Complete documentation including shock and vibration test reports, Level II military drawings, provisioning and technical documentation and Level I material certification is available.

NEWCO cast steel gate valves are available in non-rising stem (NRS) and outside screw and yoke (OS&Y) as noted. Optional trims (Brass, Stainless Steel, Ni-Cu) and special features such as clean-out plates and indicators are also available.
