Ball valves are designed to be used in a variety of applications and markets, but a V-port ball valve offers the added ability to be used as a control valve where necessary.

GZP Pipeline Ball Valves are manufactured to the latest edition of API 6D and tested to API 6D. Passed API 607 fire test standard for soft seal valves.

Double Block and Bleed functionality has been available in ball valves essentially since the developement of the trunnion mounted ball valve commonly used today.

Double block and bleed valves are used for isolation in critical applications. They also prevent product contamination and maintain system integrity.
