Victor 4000-0053 single-stage cylinder regulator CGA 320

CGA 320 single-stage cylinder regulator

The Victor 4000-0053 is a single-stage cylinder regulator built for carbon dioxide service with a CGA 320 inlet connection. It delivers a pressure range of 1 to 150 psi and is rated for a maximum inlet pressure of 3,000 psi. The brass body measures 1.97 in diameter and uses a stainless-steel diaphragm. ETL and ISO standards apply. This item is new and carries a California Proposition 65 notice.

Fits 1/4 in FNPT outlet systems

The outlet connection is 1/4 in FNPT, so it threads directly into compatible hose or manifold fittings without adapters. A 1 31/32 in supply-pressure gauge reads up to 3,000 psi, letting the operator verify cylinder contents at a glance. The single-stage design reduces component count for simpler maintenance in laboratory or industrial gas-distribution setups. Brass construction resists corrosion from carbon dioxide.

Steady delivery under continuous flow

Single-stage regulation provides consistent outlet pressure while cylinder pressure remains high, then declines gradually as the source depletes. The stainless-steel diaphragm maintains seal integrity over repeated pressurisation cycles up to the 3,000 psi limit. Gauge damping is calibrated for laboratory use rather than rapid cycling. Not suited for applications requiring constant outlet pressure from full to empty cylinder without manual readjustment.
