MAIN FEATURES
3 Piece Bolted Construction
3 piece bolted construction provides conventional through bolting of the flanged end connections, plus the option of hub or welded ends. The overall lengths of the valve are kept to a minimum and offer considerable cost, weight and space savings over conventional piping methods of double block and bleed, using separate ball valves and spool pieces.
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.
Floating Ball Design
The floating ball construction ensures maximum weight and space savings, whilst providing reliable and safe isolation up to and including ASME Class 2500
Available up to 3″ full bore and 4″ reduced bore.
Floating Ball design with robust lever operation.
Flanged connections in accordance with ASME B16.5 or API 6A, hub connectors or welded ends also available.
Integral vent valve with threaded outlet connection.
