G353A045 1.5 Inch Remote Air-Piloted Pulse Valve

G353A045: Remote Pilot Control for Dust Collector Cleaning

The G353A045 uses a separate pilot valve to control the main cleaning-air passage. The main valve stays beside the dust collector piping, while the pilot solenoid can be installed remotely or grouped in a pilot enclosure.

Two Connections with Different Jobs

The G1½ inlet and outlet carry the compressed-air pulse. A smaller G¼ port in the bonnet connects to the remote pilot circuit. These sizes serve different functions: the pilot line controls the diaphragm, while the main ports supply air to the cleaning pipe.

How Remote Cleaning Works

Opening the external pilot releases pressure from the chamber above the diaphragm. The main diaphragm lifts and the cleaning air passes through the valve. Closing the pilot allows pressure to recover above the diaphragm, shutting the main passage.

Applications in a Dust Collection System

• Baghouse cleaning: supplies the air burst to the connected filter-cleaning line.
• Sequential cleaning: works with remotely controlled pilots to operate cleaning lines in turn.
• Grouped pilot layouts: allows the pilot solenoids to be arranged together while the main valves remain at their individual air connections.

G353A045 FAQ

Is there an electrical coil on the main valve?

No. G353A045 is the remote pilot version. Electrical switching takes place at the separate pilot solenoid.

Does the G¼ connection carry the main cleaning air?

No. G¼ is the pilot connection. The G1½ ports are the main airflow connections.

Is this the same as a compression-fitting valve?

No. G353A045 has threaded main connections. A similar-looking compression-fitting valve uses a different connection arrangement and ordering code.

Can all diaphragm materials be treated as identical?

No. Material options have different temperature and media limits. The diaphragm grade and its operating range belong to the selected configuration.
