Donze regulation and safety products are part of advanced steel slab cutting and conditioning solutions in some of the largest steel mills in the world. We are revolutionizing the steel cutting process, with proprietary technology and breakthrough operational expertise.

Regulation Panels and Lines

This equipment is compact and comprises a gas pressure regulator, an electrically operated valve and safety appliances (flashback arrestors). These products allow fast and easy mounting and dismounting for periodical servicing, and with the alignment of their inlet and outlet joints they are easily installed on existing pipes. They are available for all types of oxy‑cutting gases and adapted to flow rates up to 250 Nm3 /h with 15 bar (217.5 psi) upstream and 12 bar (174 psi) downstream.

• Custom built according to customer specifications
• Capable of regulating high pressure gases – electronically controlled
• Designed to be portable and easy to install and mount
• Protected with safety flash back arrestors
• Can be completed with gas filters to enhance their service life

Flashback arrestors

Flashback arrestors are used to protect gas cylinders and pipeline outlet points (hoses and any equipment) against dangerous reverse gas flow and flashbacks.

• Large surface area flame arrestor made of stainless steel
• Extinguishes any dangerous flashback entering the device in any direction
• Temperature-sensitive cutoff
• Spring-loaded, non-return valve
• Gas inlet filter protects the arrestor against dirt contamination, extending the life span
• May be mounted in any position/orientation
• Suitable for torches and cutting machines with high flow

Regulators

• Diaphragm regulator
• Nominal inlet pressure: 50 bar (725.2 psi)
• Adjustable outlet pressure: 0.5 bar (7.25 psi) to 12 bar (174.0 psi)
• Maximum flow rate up to 800 Nm3 /h (498 SCFM)
• 1 LP gauge
• Inlet/outlet 25.4mm (1 in.) BSP F
• Suitable for any non-corrosive gas (oxygen, natural gas, acetylene…)

Options :
