Product features and applications
FA49H type flange explosion wave proof safety valve is a kind of safety valve that is able to eliminate water hammer shock wave and also can stop the water hammer shock wave. It is composed of various safety valves, and its function can not be achieved by a single safety valve. FA49H FA49H type flange explosion wave proof safety valve is generally installed in the head of water supply pipes, in order to combine block wave and eliminate wave, prevent water hammer shock wave entering into the internal water supply system along the pipelines, so as to achieve the elimination of destructive water hammer shock waves, and achieve the purpose of protecting the normal operation of system facilities and safety protection.
