Drastar DRA700 Series

dra700_with_gauges.jpg

DRA700 series from Drastar is a lock type Ultra High Purity (UHP) low pressure reducing regulator with a B.A. 25Ra surface finish.

Inlet pressures are either 3000psig (210bar) or 600psig (42bar) and outlet pressures are from 5psig (0.3bar) up to 250psig (17bar).

Drastar’s patented “push and lock type handle” allows easy and stable operation of the low pressure reducing regulator. “Locking” the pressure is easily done by pushing down the handle and this will prevent any slight change of the pre-set pressure value, typically from vibration on the gas line or ambient changes. Unlocking by pulling back the handle allows the user to make adjustments to the pressure set point.

Product highlights include:

  • Threadless type: enhanced particle prevention by adopting the locking-plate seal system (DRASTAR patent #10-0753280)
  • All works of welding, assembly, test and cleaning are performed in class 100 and class 10 clean-rooms
  • Design proof pressure: 150% of maximum rated
  • Various gauge port options including ¼” H.P.I.C, ¼” male or female swivel
  • Cv values from as little as 0.06 up to 1.2

Drastar’s regulators are oil-free, with all pressure regulators being assembled, cleaned, inspected, and packed in clean-rooms equipped with clean bench, helium detector, particle counter, ultrasonic cleaner, ultrapure water system, vacuum packaging machine.
