Total No. of Valves Installed in two blocks 12 x DN 25 (1”) and 5 x DN 10 (½”)
RESPONSE TIME ACTUATED VALVES - METHANE
  • 2 seconds open to close
  • 5 seconds closed to open
  • Two switches on actuated valves indicating open/closed.
PRINCIPLE FEATURES OF NITROGEN AND METHANE MANIFOLDS
  • Each valve has a double sealing arrangement to the outside environment
  • The void between each seal is monitored/analyzed by a flow of air through each of the voids in the manifold block and valves, ensuring that any breaches of the primary seals is detected.
  • Automatic shut down of Methane supply if leak is detected.
  • Nitrogen purging system of the Methane flow paths during a planned shut down or in an emergency situation.
  • All valves of cartridge design enabling quick change in the event of a failure and full maintenance whilst off line.
  • Actuated Valves controlled from XXX / XXX source, and spring return for fail safe.
  • Valve leakage to ANSI class VI
