Maximator® series BB block and bleed valves with metal to metal seats have a high level of safety and reliability under adverse operating conditions. Block and bleed valves are two stem manifold valves designed for blocking, bleeding and calibrating of pressure gauges and transmitters up to 22,500 psi @ R.T.

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