VALVE STAND

Our VALVE STAND for oxygen, natural gas, nitrogen or other gases or liquids are certified according to international regulations. It can regulate flow from 20 to 5.000 Nm3/h for each line.

FLAME BACK DETECTOR

The FLAME BACK DETECTOR, is a new solution devised to detect sudden increases in temperature caused by backfire, which developes in the feed pipes of the burners/injectors. The principle of intervention is based on a PT100, that is indirectly hit by a rise in temperature, which modifes the value of the resistance. This resistance difference is elaborated by PLC, which generates an alarm signal. The detect time is 2 sec.

ANTI-BACKFIRE NON RETURN VALVE

Is a device that guarantees and increases security of the oxygen and LPG/natural gas regulation valve stand in the melting plants for steel production.
The materials used in the valve are suitable for oxygen, fuel and inert gas passage. The blocking safety system valve is activated by a thermo-sensor, it works when the detonator reaches the setting temperature to bursts, and stops the flame passage by pre charged spring that pushes the closing shutter.
The response times are significantly reduced, (about 2 seconds) compared to main competitors on market that use a mechanical stop brazed with tin and longer intervention time.
The pressure drop is 0,1 bar.
