The top-entry GROVE BT1 valve is manufactured in a wide range of diameters and pressure classes. In the standard versions, the valve is suitable for transmission pipelines, pumping, compression and reinjection units, offshore platforms, onshore terminals, pig traps, measuring stations, and surge-relief skids. In addition to oil and gas applications, the valve can be used for renewable fuels service. Whenever ball valves are used in critical service applications, in situ field repairability with quick turnaround is often needed.
