Double Block and Bleed Ball 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).

These 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.

Benefits of Double Block and Bleed Valves:

  • minimized leakage points
  • reduced installation costs and maintenance requirements
  • 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
  • can be configured to connect up to most sizes of tubing with all connection styles.
