Information About SV9502H1706
The SV9502H1706 belongs to Honeywell’s SmartValve series — a line of intelligent gas controls that combine electronic ignition sequencing, gas flow regulation, and flame monitoring in one compact housing. This slow-opening model supports natural gas operation with 1/2" x 1/2" NPT inlet and outlet ports and operates at 24 VAC control voltage. It’s compatible with systems using hot-surface or intermittent pilot ignition, providing continuous safety monitoring and automatic gas shutoff if no flame is detected. The SmartValve communicates with furnace or boiler control boards, managing pre-purge, ignition timing, flame sensing, and gas modulation for optimal performance.
Key Features:
- Integrated Gas Control: Combines electronic ignition and gas valve operation in a single assembly.
- Slow-Opening Design: Provides smooth gas flow ramp-up to reduce ignition noise and improve safety.
- Intermittent Hot-Surface Pilot Ignition: Supports both intermittent and hot-surface ignition systems.
- 24 VAC Control Power: Compatible with standard low-voltage HVAC control systems.
- Flame Rectification Safety: Monitors pilot flame and shuts off gas if flame signal is lost.
- Dual Automatic Valves: Features redundant safety valves for fail-safe operation.
- Compact OEM Form Factor: Ideal replacement for original Honeywell SmartValve installations.
- Natural Gas Operation: Factory-set for natural gas; convertible to LP with optional kit.
- Diagnostic Feedback: Provides system status for troubleshooting ignition or flame sensing issues.
- Field Proven Reliability: Designed for residential furnaces, boilers, and commercial gas appliances.
The SV9502H1706 offers precise electronic control and safe, reliable operation for modern HVAC gas systems.
