Products Feature.


Gas and D/I Water High Flow Regulators(PT 3/8″ 1/2″ 3/4″ 1″) 

DR90 Series with Cv4.0 is a PT type pressure reducing regulator ideally designed to use for D/I water, general industrial gases, air or water line. 3/8”, 1/2”, 3/4”, or 1” PT type ports of connection are available. 

◈ 3/8”, 1/2”, 3/4”, or 1” PT type port of connection available 
◈ Inlet pressure is 42bar(600psig) and outlet pressures are 5bar(72psig), 10bar(145psig), 15bar(210 psig) 
◈ Panel mounting bracket available as option 
◈ Design proof pressure: 150% of maximum rated 
◈ Suitable for D/I water, industrial gases, air or water line (Cv = 4.0) 

[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.
