Isolation valve prevents explosion propagation
The Q-Flap NX inlet explosion-isolation valve (photo) is this company’s latest generation of inlet-isolation valves to prevent explosion propagation through ductwork. This improved version features magnets that hold the flap open and significantly reduce the pressure drop across the valve. This means that the suction from the dust collector only moves the product. Energy is saved since fans require less power, and product flow is improved by the dramatic reduction in pressure drop. In addition, this optimal system design allows for up to two elbows in ductwork prior to valve installation, which eases the retrofitting process. The optional auto-cleaning feature reduces downtime and speeds up cleaning. The Q-Flap NX meets or exceeds NFPA Standards requirements. It is available in carbon- or stainless-steel construction, with valve sizes ranging from 3 to 40 in. Hall 3, Stand E39 — Rembe GmbH Safety + Control, Brilon, Germany
