2/2 PULSE SOLENOID VALVES for dust collectors and soot removal Pulse (or shock) valves are used both in dust clean blowing systems for pulse bag filters, and in boiler soot removal systems. The main characteristics of pulse valves are large flow capacity and extremely short opening time (around 5 ms). These result in powerful sonic shock wave which efficiently removes dust particles (bag filters) or sediments in boiler tubes. Our valves are designed for long and reliable operation with minimum maintenance.
