Electrically Heated, Vaporizing Pressure Regulator (up to 3, 500 psig) – AVR4 Series
Brand: Parker HannifinThe AVR4 Series Electrically Heated Pressure Regulator is designed to heat/vaporize process fluid before entering a downstream analyzer system.
It is CSA, CE-ATEX certified and features a field-serviceable heat transfer element for minimal downtime.
The Parker AVR4 Series is a CSA, CE-ATEX certified, steam-heated pressure regulator that is designed to heat and/or vaporize a gas or liquid sample before entering a downstream analyzer system.
Its unique design allows the operator to disassemble the regulator and electrical heat transfer components for complete cleaning and repair of the unit, thus reducing replacement costs and minimizing downtime.
The regulator is highly compact, making it ideal for use in scenarios where space is limited, such as heated boxes and enclosures.
Features- Electrically heated transfer element is field-replaceable
- Unique compression member loads seal to body without requiring a threaded nozzle
- Available with a variety of seat materials for media compatibility
- Internally springless minimizes particle generation and gas entrapment
- Fully functional from vacuum to 3,500 psig
- Internal leak rate: bubble tight
- External leak rate: bubble tight
- Low internal volume (4.6 cc) reduces purge times
