The 1253119 & 1247732 diaphragm is the key component to control the blowing of your Norgren Buschjost pulse valve 8493635. When the valve is powered on, the diaphragm quickly releases the trapped air above it, making the main valve open fast. When the valve is powered off, it balances the pressure by releasing air through the exhaust hole, and the valve closes at once. Replace your old diaphragm with this part, and your pulse valve will work well again.
