Applications

Double block and bleed valves are most commonly used in the oil and gas industry, but can also be helpful in many other industries.

It's typically used where bleeding the valve cavity is required, where piping needs isolation for maintenance, or for any of these other scenarios:

• Prevent product contamination
• Remove equipment from service for cleaning or repair
• Meter calibration
• Liquid service near waterways or municipalities
• Transmission and storage
• Chemical injection and sampling
• Isolate instrumentation such as pressure indicators and lever gauges
• Primary process steam
