Maximator® series DBBNV Double Block and Bleed Needle Valves with metal to metal seats have a high level of safety and reliability under adverse operating conditions. Double Block and Bleed Needle Valves are three stem manifold valves designed for blocking and bleeding in test and pressure monitoring applications as well as for chemical injection or drain line isolation up to 22,500 psi (1,550 bar).

Due to the standard valve packing and Vee stem design, Maximator® double block and bleed needle valves are very compact and easy to use. In addition, manifold style valves reduce the number of fittings and space required for installation.
