The VENTEX explosion isolation valves are available in a wide variety of sizes and versions for passive explosion isolation. The valve is intended for installation in the ductwork of dust extraction / separating systems, positive or negative pressure handling systems, drying systems, or granulation systems. In most cases, the valves are resistant to the maximum explosion pressure. The valve closes against the explosion pressure wave propagating in the ductwork. The dedicated double bellmouth-shaped closure of the explosion isolation valve minimizes the disturbance of the passing flow. The explosion isolation valve is approved for application with combustible and flammable gases, dusts and gas and dust mixtures. Whenever the flow in the valve is loaded with dust, the dust content must not exceed the limits specified in the product technical data. This is imposed by the double bellmouth closure, which is pressed against a dedicated seal when the explosion isolation valve closes. Here, the alignment tolerance is very narrow and between 0.1 and 0.15 mm. An excessive dust concentration in the flowing medium may result in deposits on the valve seal or its abrasive wear, leading to incorrect explosion isolation performance. The VENTEX explosion isolation valve has a very broad selection of product versions. It is available in a wide range of diameter (from DN100 to DN50), it can be installed in horizontal or vertical orientation, and provide single or two-directional isolating action. The material versions include regular steel and stainless steel, and there is a version with an active closing mechanism.
