SOLENOID VALVE NC 3/8 321H2322 WEISHAUPT

Weishaupt 321H2322 Solenoid Valve

The Weishaupt 321H2322 Solenoid Valve is a normally closed fuel-control valve used in compatible Weishaupt oil burner systems. Its G 3/8″ connection and 20 W coil make it suitable for controlling and shutting off fuel flow during burner operation.

Designed for dependable operation in combustion systems, the valve is suitable for maintenance, overhaul and replacement applications in marine and industrial burner installations.

Normally Closed Burner Fuel Valve

The 321H2322 operates as a normally closed (NC) solenoid valve. In Weishaupt Monarch oil-burner fuel-system documentation, the 321H2322 is identified as a 20 W, G 3/8 normally closed valve.

This configuration makes the valve suitable for applications where controlled fuel shut-off is required as part of the burner operating and safety sequence.

Maintenance and Replacement

Solenoid valves are critical components within an oil burner’s fuel-control system. During preventive maintenance, the valve and associated electrical connections should be inspected for correct operation, leakage, contamination and signs of deterioration.

Before replacing an existing valve, verify the 321H2322 model, coil voltage, frequency, connection and burner configuration, as different voltage variants of this valve exist.
