Products Feature

Two Stage Low Pressure Regulators(NPT 1/4”) 

2000 Series is a 1/4” NPT type two stage low pressure reducing regulator specially designed to regulate the high pressure gas cylinder to low pressure applications more accurately and safely. Max inlet pressure is 250bar(3600psig) and outlet pressure ranges from 0.3bar(5psig) up to 20bar(290psig). 

◈ 1/4” NPT type regulator 
◈ Suitable for the high pressure labs, industrial control 
◈ Inlet pressure is 250bar(3600psig) and outlet pressures are 2bar(30psig), 5bar(75psig), 10bar(145psig), 20bar(290psig) 
◈ Panel mounting nut available as option 
◈ Design proof pressure: 150% of maximum rated 
◈ Applicable for cylinder gas, bulk gas line, research labs, analytical specialty gas, high purity gas, mixing gases, and corrosive gases. 

[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. 

※ 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. 

※ 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.
