UHP VCR type Pressure Reducing Regulators
DRA100 Series is an UHP low pressure reducing regulator with B.A. 25Ra, E.P. 10Ra, or E.P. 5Ra surface finish and applicable for high purity semiconductor manufacturing, specialty gas, and bulk gas lines as well as other facilities. Inlet pressures are 3000psig (210bar) or 600psig (42bar) and outlet pressure are 5psig(0.3bar) up to 250psig (17bar).
★ 1/4”, 3/8”, 1/2”, and 3/4” VCR type
★ Non-tied diaphragm type
★ Surfaces finishes to B.A. 25Ra, E.P. 10 Ra or E.P. 5 Ra microinch
★ Push and lock type handle (DRASTAR patent #10-1086199) mounted
★ 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
★ Applicable for Semiconductor manufacturing, specialty gases, bulk gas line and other facilities
With DRASTAR’s patented (patent #1086199) “push and lock type handle”, you can operate it easily and stably; “locking” by pushing down the handle will prevent any slight change of pre-set pressure value, which could possibly be caused by any vibration from gas pipeline or ambient applications and the other way “unlocking” by pulling it back enables you to adjust the pressure value freely again. |

| Recommendations |
|
Each product is manufactured taking into consideration of the best safety and easy manipulation. However in order to use the regulator in most safe, effective, precise and smooth way and prolong its life time, you are recommended to use the actual pressure within the range of 25% ~ 75% of its rated pressure.
