Back flap valve

Back flap valve is a mechanical device designed to prevent flame and pressure transfer between technologies during an explosion
Back flap valve is supplied with an RPD mechanism which reduces pressure losses in the piping system
by securing the sealing part in an open-locked position.
The flap isolates the explosion along the entire piping route,
so it is suitable for inlet and outlet piping to and from the filter, cyclone, mill, dryer and others.
