The Aceco Model BV1 and BV2 ball valves are available in Double Ball Designs. This option provides the unique  advantage of two valves contained in one solid body eliminating a possible leak path, reducing the amount of end  connections required as well as provide for maximum space and weight savings. The double ball valve design  provides double isolation as well as true double block and bleed capabilities  capabilities for safety and seat integrity checks allowing for peace of mind. This is accomplished through  the two physical barriers to retain pressure while working downstream of the closed valve.
