High-pressure regulators up to 414 bar and gas cylinder regulators

Up to 414 bar EWO 120 high-pressure regulator, AirCom HP regulator and GCE ProControl cylinder pressure regulator

High-pressure regulators reduce the gas pressure from a high-pressure network, a cylinder bundle or directly from a gas cylinder – up to 414 bar – to the pressure required by test equipment, a laboratory, a machine or a welding workstation.

Choose the series according to where the gas comes from and what gas it is: an air or nitrogen network up to 200 bar, a network or cylinder up to 300 or 414 bar, or a pressure regulator fitted directly to the cylinder for a specific gas.

Which series to choose

Choosing the high-pressure regulator series by gas source: network, cylinder bundle or a single cylinder — 1 network: regulators 120 (up to 200 bar) or HP (up to 300 and 414 bar) · 2 cylinder bundle: HP regulators · 3 single cylinder: cylinder pressure regulator with a connection according to DIN 477; an HP regulator only via pipework (NPT 1/4" inlet).

The main deciding factor is where the gas comes from. An air or nitrogen network up to 200 bar is served by regulators 120. Higher pressure, cylinder bundles and gases such as oxygen, hydrogen or helium are handled by HP regulators. A cylinder pressure regulator for the specific gas goes directly onto a single cylinder.

Series	Gas source	Inlet pressure	Outlet	Pressure gauges	Gases	Connection
120	air or nitrogen network	up to 200 bar	1–50 to 1–150 bar	2 included	air, nitrogen, neutral gases	G 1/4"
HP	network, cylinder bundle, cylinder	300 or 414 bar	0.1–1.7 to 1–172 bar	no, 2 NPT 1/4" ports	air, nitrogen, oxygen, hydrogen, helium, CO₂	NPT 1/4"
cylinder	gas cylinder	200 / 300 bar (acetylene 25 bar)	0–1.5 to 0–200 bar or l/min	2 with rubber guard	always one gas or group of gases	cylinder connection according to the gas

For oxygen, the HP series only up to 200 bar at the inlet. Cylinder connections according to DIN 477-1 (200 bar) and DIN 477-5 (300 bar).

Inlet and outlet pressures of the three series

Comparison of inlet and outlet pressures of regulators 120, HP and cylinder pressure regulators — p₁ = maximum inlet pressure (HP type 300 and 414 bar; cylinder regulators for 200 and 300 bar cylinders, acetylene 25 bar), p₂ = outlet pressure range. Cylinder regulators with a flowmeter set the flow rate in l/min.

Regulators 120 take air or nitrogen from a network up to 200 bar and set 1 to 150 bar. HP regulators withstand 300 or 414 bar at the inlet and set 0.1 to 172 bar. Cylinder pressure regulators connect to 200 and 300 bar cylinders (acetylene 25 bar) and set up to 200 bar.

Safety with high pressure and industrial gases

Rules prescribed by the regulator manufacturers and by the standards for cylinder pressure regulators:

Oxygen: the regulator, cylinder and hoses must not come into contact with oil or grease, and no lubricant may be used during installation – there is a risk of fire (safety instructions of the manufacturer AirCom).
Safety valve downstream of the regulator: regulators 120 and HP have no secondary venting. Protect the connected equipment against overpressure with a separate safety valve – according to AirCom, the venting of the regulator is not sufficient for this.
One regulator – one gas: use a cylinder pressure regulator only for the gas it is designed for. The cylinder connection differs according to the gas (DIN 477-1 and DIN 477-5), and flammable gases have a left-hand thread (LH).
Flammable, pyrophoric and toxic gases require trained operators, good ventilation and gas leak detectors. Some gases displace the oxygen in the air and there is a risk of asphyxiation (AirCom).
ProControl cylinder regulators have been type-tested according to ISO 2503, and all versions have a relief valve (GCE).

What you will need with a high-pressure regulator

pressure gauges for oxygen, acetylene and argon: pressure gauges for industrial gases
hoses for oxygen: GOX pressure hoses
hoses for acetylene: GAC welding hoses
protection of equipment downstream of the regulator: safety valves

Ventilek advises

First find out the highest pressure that can occur at the regulator inlet – in the network, in the bundle or in a full cylinder – and what gas it is. Choose the series accordingly, and choose a range only slightly above the pressure you want to set.

inlet up to 60 bar and secondary venting: regulators 302
water, air and neutral gases up to 40 bar: DRV pressure reducing valves
all series: air pressure regulators

What is the difference between a pressure regulator and a pressure reducing valve?: It is the same device. The term pressure reducing valve is common for gas cylinders and water, the term pressure regulator for compressed air.
Can I screw an HP regulator directly onto a cylinder?: No. The HP regulator has an NPT 1/4" inlet and no cylinder connection. For direct connection to a cylinder, there are cylinder pressure regulators with a connection to match the gas.
Which regulator is for oxygen?: Cylinder pressure regulators for oxygen (200 and 300 bar cylinders) and HP regulators up to an inlet pressure of 200 bar. Always free of oil and grease.
Does a high-pressure regulator release pressure when I reduce it?: No. Regulators 120 and HP have no secondary venting – the outlet pressure only drops once gas is drawn off. Protect the connected equipment with a separate safety valve (AirCom); regulators 120 also have a blow-off relief valve.
Do high-pressure regulators have pressure gauges?: Regulators 120 come with two pressure gauges, and so do cylinder pressure regulators. HP regulators only have two NPT 1/4" ports sealed with plugs.

Technical data according to the manufacturers EWO (series 120), AirCom (HP) and GCE (ProControl cylinder pressure regulators).
