KRASS Cutter Universal Valve

KRASS CUTTER UNIVERSAL VALVE — manual oxy-fuel cutters with dependable valves

The KRASS Cutter Universal Valve is a manual oxy-fuel cutter whose control valves set the preheat flame and the cutting oxygen. REAL GAZ supplies it with all required gases.
Universal here means the cutter can be used with a range of nozzles, so one body serves many plate thicknesses.

Supply follows EN ISO 5172, EN 730-1 and ISO 9539 principles, suitable for workshop and maintenance use.

🏭 Where KRASS Universal Cutters Are Used

🏭 Steel fabrication — operators change nozzle sizes as the plate thickness changes during the day;
🚢 Ship repair — portable cutters are carried to the hull and deck areas needing work;
🔧 Maintenance shops — a single cutter body covers many repair tasks;
🎓 Vocational training — students learn valve control and flame adjustment on a universal model.

💡 Why Choose REAL GAZ

🎯 Matched supply — gases, nozzles and accessories on the same order;
🔒 Safety support — guidance on arrestors, hoses and lighting sequence;

🔬 Quality Control & Safety

valve operation and seat inspection;
body and connection checks;
oxygen and fuel gas purity analysis;
leak testing and pressure integrity checks.

Gas cylinders supplied with the equipment comply with ADR / UN transport rules and relevant EN/ISO standards.

🛠️ Valve Care and Operation

Open valves gently; forcing a stiff valve damages the seat and creates a leak path.
Check that non-return valves and flashback arrestors are fitted at the torch or regulator, per local rules.
Have valves inspected regularly and replace O-rings or seals as soon as they show wear.

🧩 One Body, Several Nozzles

The advantage of a universal cutter is that one body works with several nozzle sizes. Keep a small set of nozzles in sizes that match the plate you meet most often, in a clean case with each size marked. Change the nozzle with the valves closed and the torch cold, using the spanner supplied, and check the seat before refitting. After a nozzle change always re-test for leaks. Keep a note of the gas pressures recommended for each size so that settings are repeatable. REAL GAZ can assemble a starter set of nozzles, hoses and gases for your cutter so that your crew is ready to work on delivery day.
