Precision Regulator

Model No. R42-201

Model No. R42-201
  • The set pressure is very precise and stable in a wide flow rate region.
  • The large relief flow route minimizes the rise in the back pressure on the OUT side.
  • Applicability to a wide voltage range enables overseas use with the same voltage specifications.
  • Feedback control type with superior followability to flow rate fluctuations
  • Employs the constant bleed model that maintains the set pressure precisely as soon as air begins flowing.
  • Easy panel installation (panel nuts included as standard)
  • Sealing-integrated model spool that also provides easy maintenance
  • A tamper-proof model that prevents unauthorized persons from adjusting the pressure unnecessarily is also available.
