Drastar DR60 Series Single Stage Reducing Regulator

Single Stage Reducing Regulators


   Products Feature.

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

DR60 Series is a 1/4” NPT type single-stage pressure reducing regulator being widely used for general plumbing and industrial gases. Mode of nickel plated brass for body and stainless steel or brass for internal parts, Teflon valve seat, and diaphragm of special rubber, DR60 series an economical model with durability and safety as well.

◈ 1/4” NPT type regulator
◈ Suitable for the general plumbing and industrial control fields
◈ Inlet pressures are 3000psi(210bar) or 600psi(42bar) and outlet pressures are 25psig (1.7bar) 50psig(3.5bar), 100psig(7bar), 200psig(14bar)
◈ Design proof pressure: 150% of maximum rated

[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.
