Description

2000 Series

Two Stage Reducing Pressure Regulators

 

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 210bar(3000psig) 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 210bar(3000psig) 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.
