Products Feature

High Flow and High Pressure Regulators(NPT or BSP 1/2″ 3/4″ 1″) 

DR70 Series is a NPT or BSP type single-stage high flow pressure reducing regulator suitable for pipeline application where high flow of water, chemical, liquid and gases are being used. Drop-preventing function of DR70 series enables stable and precise regulation of outlet pressure even facing with wide pressure variation at P1. 

◈ 1/2”, 3/4”, 1” NPT or BSP type available 
◈ Drop-preventing function is built in 
◈ Suitable for the industrial control 
◈ Inlet pressures are 420bar(6000psi) or 100bar(1450psi) and outlet pressures are 10bar(145psig), 25bar(360psig), 50bar(720psig), 70bar(1000psig), 150bar(2100psig), 250bar(3600psig), and 350bar(5000psig) 
◈ Panel mounting and wall mounting bracket available as option 
◈ Design proof pressure: 150% of maximum rated 

[DRASTAR Regulators are Oil-free] 
※ DRASTAR’s all pressure regulators are assembled, cleaned, inspected, and packed in clean-room equipped with clean bench, helium detector, particle counter, ultrasonic cleaner, ultrapure water system, vacuum packaging machine, etc. through oxygen cleaning procedure in compliance with process and regulations indicated in CGA 4.1. and or ASTM G-93 and are free of any grease or oils. 

※ Caution: Filtering (gas 7㎛ ~ 15㎛, water 15㎛ ~ 80㎛) is a MUST to use in the general gas application other than high purity gases. Otherwise, it may cause a failure to the regulators. It is strongly recommended to install filter for extension of life span and saving the maintenance expense.

     Recommendations to Use


Each product is manufactured since being taken into consideration of the best safety and easy manipulation. However in order to use the regulator in most safe and effective way, you are recommended to use the actual pressure within the range of its 25% ~ 75%. For making precise, smooth movement and to prolong product life, strongly recommended to make a use within above mentioned range.
