Free Shipping on Orders Over $363.30 USD

Precision pressure regulators control air pressures in applications where precise and dependable regulation is required, such as pneumatic instrument circuits, test stands, production checking fixtures, and industrial air gauges.

Multi-stage precision regulators maintain constant output over wide changes in flow and supply pressure:
  • Epoxy powder coat paint delivers improved corrosion resistance
  • Patented Nullmatic pressure regulation system provides reliable maintenance-free operation
Features
  • Multi-stage low-droop precision regulators maintain constant output over wide changes in flow and supply pressure
  • Epoxy powder coat paint delivers improved corrosion resistance
  • Wide selection of regulated pressures (1" to 450 psi) affords application versatility
  • Patented Nullmatic pressure regulation system provides reliable maintenance-free operation
