Double Block And Bleed Ball Valve

GMK VALVE provides high-quality Double Block and Bleed Valve solutions for industries that require safe isolation and reliable fluid control. These valves combine double isolation and bleeding functions into one compact design.

A double block and bleed system uses two isolation valves with an additional bleed valve. Therefore, it can safely remove trapped pressure or fluid between the two sealing points.

This advanced design improves safety and reduces the need for multiple separate valves. Moreover, it helps save installation space and simplifies pipeline systems.
