Overview

GROVE B5 side-entry ball valves are manufactured in a wide range of diameters and pressure classes. The valves are specified for transmission pipelines, pumping, compression and reinjection units, offshore platforms, onshore terminals, pig traps, measuring stations, and surge-relief skids. Split-body construction enables using forged materials in various grades of carbon steel, stainless steel, and high alloys, thus complying with the most severe service conditions.
