What are Double Block & Bleed Valves?

Installing a Double Block and Bleed Valve is like having three valves in one. A single valve having two seating surfaces that, when closed, provides a seal against pressure from both ends of the valve with a method of venting/bleeding the space between the seating surfaces is referred to as a double block and bleed valve in API 6D.

A few distinct designs of twin block and bleed valves exist. One design features an interior with two independently seating valves and a bleed or drain valve. Double isolation and bleed is the name of this arrangement (DIB). The DIB valve can isolate either side of the valve (bi-directionally)to vent or bleed the cavity and isolate pipework. This Val-Matic ball valve in the trunnion form offers a double block and bleed in a single valve. This design allows the valve cavity seats to be vented or bled by isolating the piping on both sides of the valve (uni-directionally).

Installation time, weight on the piping system and space are reduced when using a single, double block, and bleed valve system instead of three separate valves. Additionally, it decreases the number of leak pathways to the atmosphere, lowering the dangers associated with transporting liquids harmful to people or the environment.

What are the uses of double block and bleed valves?

When the valve cavity has to be bled, piping needs to be isolated for repair or in any of the following situations:

  1. Protect against product contamination.
  2. Removing equipment from service to clean or repair it.
  3. Gauge calibration.
  4. Liquid delivery near bodies of water or populated areas.
  5. Transfer and storing.
  6. Sampling and injection of chemicals.
  7. Instrumentation that is isolated, such as pressure gauges and level gauges.
  8. First-stage steam.
