Description
The Honeywell L404F1243 Pressuretrol Controller is a reliable, field-proven pressure control solution engineered for steam heating systems, compressed air applications, noncombustible gases, and non-corrosive fluids. Designed for demanding hydronic and steam boiler environments, this controller delivers precise pressure switching with a rugged SPDT snap-action mechanism.
Key Features
- Operating pressure range: 5–50 PSI for broad system compatibility
- Differential pressure range: 6–14 PSI for adjustable switching sensitivity
- SPDT snap-action switching — Make R-W, Break R-B on pressure rise
- Dual voltage compatibility: 120VAC / 240VAC
- Suitable for steam, air, noncombustible gases, and non-corrosive fluids
- Compact, durable construction built for long-term boiler room service
How It Works
The L404F1243 monitors system pressure and actuates its SPDT snap-action switch when the set pressure is reached. On a pressure rise, the R-W circuit makes (energizes) and the R-B circuit breaks (de-energizes), enabling precise control of burners, pumps, or other system components. The adjustable differential allows technicians to fine-tune the switching range to match system requirements.
Applications
- Steam boiler pressure control
- Compressed air system switching
- Noncombustible gas pressure monitoring
- Non-corrosive fluid pressure control
