400325-117 Pulse Valve Solenoid Coil

400325-117 Replacement Coil for Pulse Jet Cleaning

The 400325-117 solenoid coil fits over the armature tube of a matching valve operator. When the dust collector controller energizes the coil, the magnetic field moves the armature and opens the pilot passage. The resulting pressure change lets the main valve release a burst of compressed air into the filter cleaning line.

Replacing a coil during baghouse maintenance

The coil can be serviced separately when a fault is traced to the winding and the rest of the valve is serviceable. In a baghouse with several cleaning rows, each output from the controller switches the coil for its own pulse valve.

Frequently asked questions

Which part does 400325-117 identify?

It identifies the solenoid coil. The valve body, armature and diaphragm are separate parts of the assembly.

What determines whether the coil fits?

Match the original coil reference, the supply voltage and frequency, and the mechanical and electrical connections on the valve operator.

Can a coil replacement fix a valve that leaks air?

A replacement coil addresses a fault in the winding. A valve that leaks while closed can have a separate problem at the diaphragm, seat or pilot passage.
