Information About SV9520H8042
The SV9520H8042 is part of Honeywell’s SmartValve™ series, combining gas flow control, pressure regulation, and ignition sequencing in one unit. Built with a ½″ NPT inlet/outlet and a slow‑opening regulator, it’s compatible with a wide range of furnaces, boilers, and rooftop heating applications. It operates on low‑voltage control from the system transformer and integrates diagnostics such as LED indicators for system status. Commonly used as a direct OEM replacement for Lennox/Armstrong/Ducane part numbers 28M95, 28M9501, and 20430701.
Key Features:
- Brand & Part Number: Honeywell SV9520H8042 — original OEM valve used in multiple furnace brands.
- Low-Voltage Operation: Accepts 24 VAC control signal from system transformer for ignition and gas modulation.
- Slow-Opening Regulator: Ensures steady gas pressure and minimizes pressure shock during ignition.
- ½″ NPT Body: Standard inlet and outlet fitting size for widespread furnace compatibility.
- Ignition Integration: Interfaces with hot-surface ignition systems, enabling prepurge, postpurge, and ignition sequencing.
- Manual Shut-Off: Provides emergency control over gas flow for safety and maintenance.
- LED Diagnostics: Built-in LED status indicator enables quick troubleshooting of ignition and system faults.
- Cross-Compatible: Direct replacement for Lennox/Armstrong/Ducane part numbers, ensuring wide OEM support.
The SV9520H8042 delivers the reliability and precision required for safe and efficient operation of hot-surface ignition heating systems.
