DRASTAR – 072 Series Single Stage Low Pressure Reducing Pressure Regulator (NPT 1/4”)

Description

072 Series

Single Stage Reducing Pressure Regulator

 

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

072 Series is a 1/4” NPT type single-stage low pressure reducing regulator being most extensively used for gas cylinder and precision industry.

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 regulator.
◈ Inlet pressures are 3000psig (210bar) or 600psig (42bar) and outlet pressures are 25pisg (1.7bar), 50psig(3.5bar), 100psig(7bar), 250psig(17bar), 500psig (35bar)
◈ Panel mounting nut or wall mounting bracket available as option.
◈ W072S-0000x-1O: W model is only for Liquid or Water.
◈ Design proof pressure: 150% of maximum rated.
◈ Applicable for research labs, industrial gas control, gas cylinder, general gas line, bulk gas line, analytical application, ultra-pure gases, mixing gases, corrosive gases as well as liquid lines.
◈ 2-ports, 3-ports, 4-ports and 5-ports, 6-ports available.
 * Pressure Conversion 14.5 PSIG = 1 bar 145 PSIG = 1 MPa

[DRASTAR Regulators are Oil-free]
DRASTAR’s all pressure regulators are assembled, cleaned, inspected, and packed in clean-rooms 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.
