Medium & High Pressure Block & Bleed Valves
Applications Block Bleed Valve
- Pressure isolation between the main pipeline and the instrument
- Vent / drain of pipeline loops that cannot be drained/vented with the main pipeline.
- Usually ball valve style and may be positioned at the top or bottom of the pipeline.
- Used on a vessel for isolation of the pressure tapings when measuring the differential pressure.
- Used on a filter for isolation of the upstream and downstream pressure tapings when measuring the differential pressure across the filter.
- Doble block and bleed used for vent / drain of the filter bowl.
