Victor 4000-0002 Two Stage Cylinder Regulator CGA 320

SKU CH-YWQV-0V5EM

A two-stage cylinder regulator for carbon dioxide service with a CGA 320 inlet, 1 to 150 psi delivery range, and nickel-plated brass body

  • Two-stage design delivers stable 1 to 150 psi outlet pressure
  • CGA 320 inlet fits standard carbon dioxide cylinders directly
  • Nickel-plated brass body resists corrosion for long service life
  • Stainless steel diaphragm ensures consistent pressure control under load
  • ETL and ISO standards confirm verified safety and quality

Two-Stage CGA 320 Regulator

The Victor 4000-0002 is a new two-stage cylinder regulator built for carbon dioxide service with a CGA 320 inlet connection. It delivers outlet pressure from 1 to 150 psi through a quarter-inch female NPT outlet. A nickel-plated brass body and stainless-steel diaphragm handle a maximum inlet pressure of 3,000 psi.

Upgrade from single-stage units

This regulator replaces single-stage models when downstream pressure must stay steady as cylinder pressure falls. The two-stage design reduces delivery-pressure drift so the jump is worth it for processes that need consistent flow without frequent readjustment.

Sustained-load behaviour

Under continuous demand the stainless-steel diaphragm and nickel-plated brass body maintain the set delivery pressure across the full 1 to 150 psi range. The 1 31/32 in gauges show supply pressure up to 3,000 psi and outlet pressure so the operator can verify stability during extended runs.

Questions about this item

What inlet connection does the Victor 4000-0002 use for the cylinder?

The regulator connects to the cylinder through a CGA 320 inlet fitting.

What is the correct sequence for pressurising this two-stage regulator?

Open the cylinder valve slowly, then turn the adjusting knob clockwise until the delivery gauge reads the desired pressure between 1 and 150 psi.

When should the stainless-steel diaphragm be inspected or replaced?

Inspect the diaphragm if delivery pressure becomes erratic or if the regulator fails to hold the set pressure within the 1 to 150 psi range.
