The 400 Series valves are suitable for lowpressure systems (0.5–1.5 bar), and highpressure systems (0.5–7.5 bar). The Series 400 is a range of diaphragm valves suitable for dust collector applications, in particular for reverse pulse-jet filter cleaning of filter bags, cartridges, envelope filters, ceramic filters and sintered metal fibre filters. These valves have been designed to be installed on flat surfaces or square/ rectangular tanks. They are called “full immersion” because they draw the compressed air directly from the tank, with higher pneumatic performance. Upon request they can be supplied complete with the blowtube and counter flange. The valve is fixed to the tank with a special counter flange and fixing screws.
