G353A046 1.5 Inch Dual Stage Pulse Valve

G353A046 Dual Stage Valve for Baghouse Pulse Cleaning

The G353A046 releases compressed air into a dust collector cleaning pipe. Its dual diaphragm arrangement uses a small pilot stage to operate the main diaphragm. The external pilot connects through a G⅛ port, while the G1½ threaded connections carry the main airflow.

Compact Pilot Stage Above the Main Body

A smaller pilot bonnet sits above the main diaphragm cover. The aluminum angle body turns the airflow through the valve, with stainless steel springs inside. The standard G353A046 configuration uses a CR diaphragm; FPM is a separate material option.

Where G353A046 Fits

In a pulse jet baghouse, G353A046 controls the burst of air sent to the filter-cleaning pipe. A sequential controller can switch the external pilots in turn, cleaning separate rows of filters. Pilot valves can also be grouped in a remote enclosure while the main pulse valves remain beside the cleaning lines.

The cleaning pulse dislodges accumulated dust from the filter surface. G353A046 serves the compressed-air circuit; the dust-laden process stream passes through the collector filters.

Frequently Asked Questions

Does G353A046 have a coil on the main valve?

The main valve is remotely piloted. A separate electrically switched pilot provides the control signal.

What does dual stage mean?

The smaller pilot diaphragm controls the larger main diaphragm. This separates the control passage from the main cleaning-air passage.

Are the main ports and pilot port the same size?

No. G353A046 has G1½ main ports and a G⅛ pilot connection. These connections perform different jobs.

Does a compression fitting version use the same model?

No. G353A046 is the threaded version. A compression fitting design has a different ordering code and connection arrangement.
