The neutral gas large flow pressure regulator allows a standard pressure to deliver from 20 to 280 NM3/H. It can be used as a first pressure regulator, in neutral gas, to supply several dozen welding stations.

It is recommended to mount this regulator only on bottles of B50 = 10 m³ or on bundles of bottles.

Second stage pressure regulator for neutral gases (nitrogen, argon) suitable for applications using pure and inert gases. 

Equipped with a stainless steel diaphragm, output pressure adjustment from 0-35 bar.

Allows a very stable output pressure and a very precise adjustment.

Perfect for feeding laser cutting machines.

Discover the bottle regulator with pressure gauge from the EWM brand at HD Soudage. Compliant with ISO 2503, this single stage regulator offers precise and continuous adjustment up to 230 bar.

Equipped with a manometer to display the pressure, this quality product simplifies your welding operations

The DEI regulator for Argon/CO2 gas cylinders is the essential tool for professional welders aiming for excellence in their work while achieving significant gas savings. Don't let pressure spoil your welds; opt for performance, choose the 3-in-1 regulator.

Perfectly adapted for the use of pure and inert gases that need a very stable outlet pressure, as well as a very fine setting of this outlet pressure, equipped with a stainless steel diaphragm.

Perfectly adapted for the very specific power-supply of the electrical TIG/MIG welding units, the built-in adjustment wheel is graduated from 0, 6, 8, 10, 12, 15, 18, 22,26 l/mn with an extra maxi setting for a possible inerting operation (neutral atmosphere).

Discover our armored regulator from the 3S range, designed according to EN 585 / ISO 2503 standards for maximum durability and safety. It features a monoblock brass body, a shock-absorbing cellular polychloroprene coating, and dustproof pressure gauges.

The LB21 regulators are simple pressure regulators, each of whose two gauges is individually covered with a soft rubber casing. Their compact size and the rear regulator/bottle attachment reduce shocks.

The Dynaflow is a precise flow regulator, requiring a stable inlet pressure of 3.5 bars. It is ideal for fine-tuning flow rates in various applications and can handle up to 150 l/mn for different gases (O2, He, H2, N2, Air, and mixtures). Custom options are available upon request.
