PARKER 减压阀 IR4004S2K4PXX4B

parkerhannifin corporation’s veriflo division presents the ir4000 series internally threadless pressure regulator for instrument/analyzer and semiconductor applications. the internal threadless design minimizes purge times, and reduces carrier and calibration gas usage. the ir4000's seat materials meet the re for corrosive and/or higher temperature media re.

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

the ir4000 is a high pressure regulator that canbe ordered with a variety of options to meet a wide range of system design re.

unique patented compression member loads the seal to the body without re a threaded nozzle or additional seals to atmosphere.

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

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

positive upward and downward stops increases cycle life by preventing 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 or nitrogen).
the use of inconel®, hastelloyc-22®, and elgiloy® provide superior corrosion resistance and high repeatability.
close tolerances and tight alignment of moving components minimize hysteresis.
unique carrier design disperses gas uniformly through the regulator to improve purging.
