PARKER 减压阀 IR4004S2K4PXX4B

parkerhannifin corporation’s veriflodivision presents the ir4000 series internallythreadless pressure regulator for instrument/analyzer andsemiconductor applications. the internal threadless designminimizes purge times, and reduces carrier and calibration gasusage. the ir4000's seat materials meet there for corrosive and/or higher temperaturemedia re.

 instrument applications include gas  management systems in petrochemical/refineriesand process analyzer systems. semiconductor applicationsinclude general purpose gas management (air, clean dry air(cda), and plant nitrogen).

the ir4000 is a high pressure regulator that canbe ordered witha variety of options to meet a wide range of system designre.

unique patented compression member loads the seal to thebody without re athreaded nozzle or additional seals to atmosphere.

selection of seat materials for media compatibility andtemperature applications.
meets nace standard mr0175.
o2 cleaned.
fully swept design.
internally threadless seat design promotes long seat life.

convoluted, hastelloy c-22® diaphragm provides highcorrosion resistance and increases cycle life.

positive upward and downward stops increases cycle life bypreventing over stroking of the diaphragm.
low internal volume reduces cycle and purge time.
captured bonnet allows for safety venting.
standard units can be dome loaded (with clean dry air ornitrogen).
the use of inconel®, hastelloyc-22®, and elgiloy® providesuperior corrosion resistance and high repeatability.
close tolerances and tight alignment of moving componentsminimize hysteresis.
unique carrier design disperses gas uniformly through theregulator to improve purging.
