  • Double Block & Bleed Valves are designed to reduce the diameter & non-reduced diameter. The valve flow resistance is relatively small.
  • These DBB valves keep the system fluid intact, control fugitive emissions or leakages and can be used in a wide range of applications.
  • The ball valves rotate to 90 degrees making it easy and quick opening & closing.
  • These are made up of polytetrafluoroethylene and some more flexible materials.
  • These provide a good, soft seal.
  • Design for ease of field service and maintenance 
  • As it has PTFE, which is good lubrication, there are fewer chances of friction and wears increasing its life.
  • The balls and seat pair of the sealing pair will not wear & tear easily and quickly.
  • There is a built-stem structure that eliminates the valve stem when under fluid pressure.
  • Its fire-resistant, anti-static structure makes it suitable for transporting natural gas, oil and gas pipelines.
  • The instrumentation ball valve is suitable for transporting slurries, viscous and solid particles.
