Drastar 082 series pressure reducing regulator

Drastar 082  High pressure reducing regulator

     Products Feature

High Pressure Reducing Regulators(NPT 1/4")

082 Series is a 1/4” NPT type single-stage high pressure reducing regulator designed to use for gas cylinder and all high pressure gases more easily and safely with “Piston-Diaphragm” which Drastar specially developed.

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.

◈ 1/4” NPT type high pressure regulator
◈ Drastar’s specially developed “piston-diaphragm” mounted
◈ Inlet pressure is 6000psi(420bar) and outlet pressures are 650psi (45bar), 1000psig (70 bar), 2000 psig (140 bar), 3000 psig (210 bar), 4500psig(310bar)
◈ Panel mounting nut or wall mounting bracket available as option
◈ Design proof pressure: 150% of maximum rated
◈ Applicable for gas and liquid in the field of various high purity gases, corrosive gases, pharmaceutical line, research labs, etc. (082S model made of stainless steel 316L for its internals and body)

[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

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.
