AMSE B16.10 overall length
Allows the replacement of single isolate ball valves with the increased safety of true double isolation, without the need for expensive pipework modifications.
Single Piece Body
The single piece body with threaded end inserts provides the most compact overall length and reduces potential leak points to an absolute minimum.
Full Through Bore
Valves are available with full bore sizes in accordance with API 6D, ensuring maximum flow for increased production rates and allowing pigging of the pipe line.
Non Intrusive Trunnion Plate
The integral trunnion plate design reduces leak paths through the body.
