Do You Need API 6D Certified Omni DBB Expanding Plug Valves? Order from Keystone!
Looking for a dependable valve for your flow systems? The omni DBB expanding plug valve is designed to meet strict API 6D standards and offers the strength and reliability you need. It comes in sizes from 2″ to 36″ with reduced bore or full bore options. These valves can handle pressure classes from ASME 150 to 900 and work in a wide range of temperatures, from –29 °C up to 200 °C (–20 °F to 392 °F). They are also available for extreme cold, going as low as –46 °C (–50 °F).
Where It Works Best
This valve is an excellent choice for places that demand zero leakage and maximum safety. Common uses include:
- Metering or calibration loops
- Fuel stations and storage terminals
- Blending facilities for liquids such as biofuel
- Tank farms and depots
- Jet fuel systems
- Offshore fuel handling setups
- Safety-focused lockout/tagout (LOTO) systems
These valves are approved and certified by leading industry standards, including API 6D, CE–PED, ATEX, CRN, NACE, API 607, API 6FA, ISO 15848, and SIL 3.
Simple Operation Options
You can choose how you want to operate these valves. They are available with hand-wheels, gear operators, or actuators. That means you can open and close them manually, with mechanical assistance, or with automated controls. The flexibility makes it easier to match the valve to your exact setup.
Why It Is a Smart Choice
An expanding plug valve with a double block and bleed (DBB) or double isolation and bleed (DIB) configuration offers multiple benefits:
- Reliable seal : It seals tightly on both sides to prevent leaks.
- Easy cavity testing : You can check the space between seals without removing the valve.
- Space saving : One valve replaces the need for multiple valves and extra fittings, making your system cleaner and simpler.
Designed for Safety and Reliability
In industries like fuel handling or high-pressure liquid transfer, safety is not optional. The expanding plug design makes sure both upstream and downstream sealing points work independently. If you need to check the cavity or confirm system integrity, you can do so without affecting the entire pipeline. This makes maintenance faster and safer.
Proven in the Field
These valves are found in many demanding applications. They are trusted in fuel stations, jet fuel supply systems, tank farms, offshore loading, and more. Each use benefits from the valve’s ability to handle high pressure, extreme temperatures, and the need for a secure seal.
