AquaMatic – 8320A173V – Brass NEMA 3, 7, 9 Explosion Proof Solenoid 220/50 – Pipe Size 1/4 Inch NPT

The AqMatic 1075635 (8320A173V) is a brass NEMA 3, 7, and 9 explosion-proof, 3-way solenoid valve designed for pilot control of diaphragm-operated valves in hazardous or classified environments. Configured for 220V / 50Hz operation with 1/4 inch NPT connections, this solenoid provides controlled actuation while meeting enclosure requirements for environments where flammable gases, vapors, or dust may be present.

This model is used across V42, V46, and VAV diaphragm valve systems, where solenoid-driven pilot control is required for valve sequencing, filtration cycles, and automated flow control. The 3-way configuration alternates between applying and venting control pressure, enabling consistent valve operation under system demand.

Unlike standard NEMA 1 or NEMA 4 solenoids, this configuration is built for classified locations, where electrical components must be contained to prevent ignition of surrounding atmospheres. The brass body provides durability and corrosion resistance, while the explosion-proof enclosure supports installation in industrial process environments requiring higher safety standards.

This configuration is typically selected in systems operating on 220V / 50Hz power, particularly in international installations or facilities with hazardous area classifications.
