Description

The non-return valve Atex with mechanical activation is suitable for dust explosion isolation. Many industrial suction systems require simple isolation systems. The purpose of the non-return valves it to protect the suction horizontal lines with a dust maximum concentration of 1/10 of the LEL (lower explosion limit) and a suction speed included between 15 and 30 m/s. The stainless steel flap opening angle is 25° in the closed position plus additional 35° during the flow. Therefore, the total angle is 60° degrees which implies a low pressure drop but fast enough to close and stop the explosion.
