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.
