DR80 Series

High Pressure Reducing Regulators

Products Feature

Ultra High-Pressure Regulators(NPT 1/4″ 1/2″)

DR80 Series is a NPT type ultra-high pressure reducing regulator. With the “piston diaphragm “, which Drastar specially developed, DR80 Series is suitable to regulate ultra-high pressure gases and liquids up to max. 700 bar (10000 psig) more safely. As body and all internal parts are made of stainless steel 316L material, it is suitable for corrosive gases and liquids as well.

◈ Suitable for the high pressure labs, industrial control
◈ Inlet pressures are 700bar(10000psig) or 420bar(6000psig) and outlet pressures are 70bar(1000psig), 150bar(2100psig), 250bar(3600psig), 350bar(5000psig), 500bar(7200psig), 700bar(10000psig)
◈ Panel 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.
