SMARTOP™ - is an exclusive and ergonomic cylinder valve making the handling easier. Its structure ensures safety, comfort and efficiency:

  • on/off levers enables the quick shut-off of the gas in the emergency situation and eliminates the risk of incomplete closure of the valve,
  • by simply moving the lever, you can quickly open and close the cylinder valve, what is a time saving compared to standard valve operation,
  • double action opening for additional safety: progressive opening provides reduced flow and the cylinder is open gently, so that connected equipment is not damaged by a sudden high pressure surge,
  • low flow lever to allow for fast and easy purge,
  • integrated flow limitation guarantees safe opening at high pressure and assures additional protection in case of accidental opening of the cylinder valve,
  • SMARTOP™ is equipped with the Residual Pressure Valve and Non-Return Valve that prevent contamination due to atmospheric backflow,
  • built-in pressure gauge provides visual indication of the gas volume,
  • an ergonomic metallic cap ensures comfort and security.
