DAUBLE BLOCK & BLEED PLUG VAVLE (DBBV)

Introducing Double Block & Bleed Plug Valve (DBBV). These valves are specifically developed for Storage Tanks, Airport fueling systems for safe isolation of fuel hydrants, Fuel loading services for safe and reliable shutoff at rail, truck and ship loading manifolds. Also widely used in Metering Stations where flow meters require calibration to verify there accuracy. Design Specialities are Friction-free operation (Opening & Closing), less weight and space required, special pressure relief mechanism.
