Double Block and Bleed Valves
Double Block and Bleed Valves are space saving valves that eliminate the need for large and complicated multi-valve systems. BuTech double block and bleed needle valves (N-N-N) are designed for pressures up to 60,000 PSI (4137 bar) at 72°F (22°C) and our double block and bleed ball valves (B-N-B) are designed for pressures up to 15,000 PSI (1034 bar) at 72oF (22oC). Benefits are minimized leakage points, reduced installation costs and maintenance requirements, as the valves allow sections of a piping system to be isolated for maintenance, with a drain valve between them, insuring that unwanted pressure doesn’t get into the section being serviced.
BuTech double block and bleed valves can be configured to connect up to most sizes of tubing with all connection styles. Double block and bleed valves are primarily made from 316 stainless steel; however they can be machined from other machinable alloys with special seal materials to meet your specific needs.
