NPR4100 Series Negative Pressure Regulator

Negative Delivery Pressure Regulator

Value Proposition:

The NPR4100 Series regulator offers negative delivery pressures with the use of low pressure gas sources.

This regulator is specifically designed to regulate negative pressures down to -26 in. Hg vacuum (100 Torr). Close tolerances and tight alignment of moving components minimize hysteresis and improve cycle life. Convoluted, Hastelloy C-22® diaphragm provides high corrosion resistance and increases cycle life.

Product Features:

  • Unique compression member loads the seal to the body without requiring a threaded nozzle or additional seals
  • Internally threadless design reduces particle generation The low internal volume reduces purge
  • The low internal volume reduces purge times
  • Positive upward and downward stops increase cycle life by preventing over stroking of the diaphragm
  • Selection of seat materials for media compatibility and temperature applications
  • Unique carrier design disperses gas uniformly through the regulator to improve purging
  • Oxygen cleaned in accordance with ASTM G93 Level C
