Description
DRA700 (Lok type)
Lock type Pressure Reducing Regulator
Lock type Low Pressure Regulator(1/4” 3/8” 1/2” 3/4”)
DRA700 Series is a lock-type UHP low pressure reducing regulator with B.A. 25Ra surface finish and applicable for semiconductor hook-up line and bulk gas line, etc. Inlet pressures are 3000psig (210bar) or 600psig (42bar) and outlet pressure are from 5psig (0.3 bar) up to 250psig (17bar).
★ Lock type economical regulator
★ Surfaces finishes to B.A. 25Ra 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 hook-up line of Semiconductor process
※ 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.
