DBB Valves

OG Double Block and Bleed valves feature two ball valves with a bleed/vent function. They are available in a Split-Body Bolted design in either a Trunnion or Floating type. Body construction can be forged or cast. Valve seats can be soft or metal. Double Block and Bleed (DBB) and Double Isolation and Bleed (DIB) valves are available. With a DBB valve, the seats do not rely on an external mechanism to relieve pressure, while DIB valves require an external relief system.
