Standard Two-Stage Regulators

Our two-stage regulators are designed to provide accurate, fluctuation free delivery for precision applications in general laboratory use.  The first stage reduces the inlet pressure by over 90% and the large second stage diaphragm ensures accurate delivery pressure.  Our two-stage regulators are precision built to latest BS EN ISO 2503 and BS EN 7291 standards, to provide maximun accuracy and safety.

These regulators have the additional feature of being able to pipe away gases from the relief valve port, and comply with the stringent requirements of BS EN 7291.

Features: Forged brass body.  Safety Valve.  50mm dia dual scale safety pattern pressure gauges.  Captive pressure adjusting screw.

Regulators are available for most common gases in either side or base entry with inlet threads suitable for any local cylinder connection standards.  Regulators are also available with NEVOC, DIN & CGA type fittings.
