The GROVE B4 valve is constructed of forged components bolted together in a side-entry design.

Manufactured in a wide range of diameters and pressure classes.  Grove B4 side-entry ball 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 the use of forged materials in various grades of carbon steel, stainless steel, and high alloys to comply with the most severe service conditions.
