Products Feature

Relief / Back High Pressure Regulators(NPT 1/4” 1/2”) 

088 Series is a 1/4” and 1/2” NPT type back-pressure regulator suitable for water, chemical, liquid, gas, etc. Having Cv=0.05 or 0.6 and made of stainless steel 316L, 088 Series is specially suitable for high pressure from 5bar (72psig) up to max 700 bar (10,000psig). 

◈ 1/4” or 1/2” NPT back-pressure regulator suitable for high pressure 
◈ Controlled pressure ranges: 0.5bar~25bar, 0.5bar~50bar, 10bar~100bar, 20bar~250bar, 30bar~500bar, 40bar~700bar 
◈ Wall mounting bracket option 
◈ Design proof pressure: 150% of maximum rated 
◈ Applicable for water, chemical, liquid, gas, etc. 

[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


Each product is manufactured 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.
