Double Block & Bleed Gauge Valves

For gauges, switches and pressure transmitters: two valves with a single outlet, combining isolation, calibration and venting.

A instrumentation valve

Double Block & Bleed Gauge Valves

Double Block & Bleed Gauge Valves are compact, integrated instrumentation valves designed to provide dual isolation and controlled bleeding of process media from pressure gauges and instruments. The two independent isolation barriers enhance system safety and allow the instrument to be isolated for maintenance, calibration, or replacement without disturbing the main process line.
