Why it is specified

The valves that get fitted a hundred times on a plant and thought about once. Stocked across the common sizes, with the actuation interface already on top so motorising one later is a bolt-on job.

Typical applications

  • Air and gas lines
  • Cooling water isolation
  • Fire main isolation
  • Tank inlet and outlet

Options and executions

  • Limit switch box
  • Lockable handle
  • Pneumatic or electric actuation
  • Stem extension for insulated pipework
