A large pilot-operated diaphragm valve (10) adapted to deliver a compressed air pulse from its outlet (16), comprising a valve top (20) and valve trigger assembly {62) co-operative to cycle a diaphragm (18) away from a seat (24) and back to the seat with an accurate response to a timed energisation applied to the valve trigger by an electric solenoid or external pneu- matic signal pulse. The valve top and trigger subassembly en- close a reciprocable hollow plunger (60) held against a seat (50) by a reciprocable solid plunger (68) held by spring force and pilot air pressure against a seat (61) positioned at one end of a hole (76) passing axially through the hollow plunger (60). The valve (10) delivers a high energy pulse suitable for shak- ing dust collector bags or assisting particulate material out- flow from tapered outflow material storage hoppers and fea- tures an ability to deliver such pulses with less consumption of compressed air than a widely-used known equivalent duty two-stage diaphragm valve.
