BuTech Block and Bleed Ball Valves

• Fewer leak points by eliminating multiple connections and fittings
• Lower fugitive emissions through a reduced number of potential escape paths
• Compact footprint that saves valuable space on instrumentation panels and skids
• Faster installation with fewer components to assemble, align, and pressure test
• Enhanced reliability by reducing vibration-related stress on pipework and connections
• Safer maintenance procedures by allowing pressure to be safely vented and isolation verified before opening the system

The result is a safer, more efficient, and easier-to-maintain solution for high-pressure instrumentation, process control, sampling, and isolation applications.

All BuTech Block & Bleed Ball Valves use the same core construction:

• Cold-worked 316 stainless steel body.Cold working makes 316 stainless steel stronger while keeping its corrosion resistance. That lets a compact manifold handle 10,000 to 15,000 PSI without a bulky body.
• PEEK seats.PEEK is a high-performance engineering plastic. It stays strong under high seating loads and resists a wide range of process chemicals, so the valve shuts off tightly over repeated cycles.
• Viton O-rings as standard, 0°F to 400°F (−18°C to 204°C).They suit most hydrocarbon and general process service across a wide temperature range.
• Optional O-rings for other media and temperatures.Buna-N (-BN), EPR (-EP), or a high-temperature option rated to 500°F / 260°C (-HT). Choose the seal for your fluid and temperature, then add the suffix to the part number.
• Vee stem vent port.The central needle valve releases the pressure trapped between the two ball valves in a controlled way. The operator vents gradually instead of releasing it all at once.
• Quarter-turn operation with built-in stops.Each ball valve goes fully open or fully closed with a 90° turn. The stops make the open and closed positions clear, which cuts operator error in the field.
• Full port.The flow path isn't restricted when the valve is open, so it adds very little pressure drop to the instrument line.
• Flow in either direction.The valve can be installed either way round, which makes panel layout simpler.
• Custom solutions.BuTech can engineer versions beyond the standard range. Specialty alloys and special seal materials are available on request. [haskel.com]

DBB106-18-18 means a 10,000 PSI floating ball valve with a 0.375″ port and 9/16″ M/P connections on both ends.
DBB1564M-18-18 means a 15,000 PSI trunnion valve with a 0.375″ port, a 1/4″ M/P bleed port and 9/16″ M/P connections on both ends.
To add an optional O-ring, insert its suffix after the model, for example DBB1564M-BN-18-18.

Note: The working pressure is limited to whichever is lower, the valve rating or the rating of the selected end connection. For example, the trunnion valve with 3/4″ FNPT connections is rated to 10,000 PSI (690 bar)
