Gas Dosing Properties - Closing and Opening

  • Idealized measurement protocol: Teh handwheel is kept stable for one minute after every turn. The reaction is fast and the throughput is stable.
  • Durinf the first 3 turns following the open position the diaphragm does not touch the valves seat.
  • When usind the valve at 20°C control in the range between 10-9 and 10-10 mbarl/s is ot possible due to physical restrictions (red area in the diagram). The valve is then tight aufter the 9th turn. Control in this area needs heating.
  • The maximum throughput is 60 mbar*l/s.

Gas Dosing Properties - Setpoints

  • Actual measurement protocol: Different leakrates (=throughput) are being appraoched and held for 20 seconds.
