Information About WV8840B1141
The WV8840B1141 is part of Honeywell’s WT8840 series, engineered for use in residential and light commercial standing pilot water heaters. It uses an immersion well with an integrated NTC temperature sensor for accurate water temperature monitoring. Powered by a thermopile heated by the pilot flame, it operates independently of external electrical sources, making it dependable even in power outage conditions. The valve is compatible with CS8840 pilot assemblies and offers a wide operating temperature range, durable mechanical components, and reliable environmental resistance.
Key Features:
-
Integrated temperature sensing: Equipped with an NTC sensor in an immersion well for precise water temperature control.
-
Self-powered operation: Runs on thermopile energy generated by the standing pilot flame, requiring no external electrical connection.
-
Precise gas regulation range: Supports natural gas input from 30,000 to 85,000 Btuh for controlled heating performance.
-
Standard body configuration: 90° inlet with 1/2-inch NPT and 1/2-inch inverted flare outlet for straightforward installation.
-
Control input flexibility: Accepts millivolt signals from 350 mV to 850 mV (open circuit) for compatibility with pilot assemblies.
-
Wide operating and storage temperature ranges: Functions from 0°F to 150°F with storage capability down to -40°F.
-
High humidity tolerance: Operates reliably in up to 95% non-condensing humidity at 104°F.
-
Upright mounting requirement: Designed for vertical installation to ensure correct sensor and valve operation.
The WV8840B1141 delivers the reliability and precision required for consistent hot water production in standing pilot water heater systems.
