4. Double Block & Bleed Valves
• At YDB Valves, we engineer high quality double block and
bleed valves customized to match process requirements. All
double block and bleed valves at YDB valves are
manufactured under control of ISO 9001 to ensure process
integrity.
• Why YDB Double Block and Bleed Valves Are Preferred by
Customers?
• Double block and bleed (DBB) valves provide a single valve
that can simultaneously cut off/isolate the downstream and
upstream systems. In the block and bleed configuration,
needle valves or ball valves are used as drain valves or bleed
valves while ball valves are used as isolation or block valves.

5. Advantages of Double Block and Bleed Valves
• Double block and bleed valves are ideal for critical processes
and widely used for hazardous fluids and high pressure
systems. Applications where double block and bleed valves
and double block and bleed ball valves are used include gauge
isolation, chemical seal isolation, chemical injection
connection, chemical instrument isolation, direct mounting of
instruments, sample connection, gauge isolation remote
mounting of instruments and instrumentation drain.
