It uses an integrated temperature sensing element within an immersion well to provide accurate temperature control without external sensors. Powered by a thermopile heated by the standing pilot flame, it operates without the need for external electrical power, maintaining functionality during power outages. This valve supports a regulation range from 30,000 to 85,000 Btuh, operates within a broad temperature range, and features a standard 90° inlet/outlet body configuration for straightforward installation. Key Features: Integrated temperature sensing: Utilizes an internal sensor in an immersion well for precise water temperature control. Self-powered operation: Powered by a thermopile heated by the pilot flame, eliminating the need for external electrical power. Natural gas compatibility: Supports a regulation range from 30,000 to 85,000 Btuh for efficient heating performance. Standardized body design: 90° inlet with 1/2-inch NPT and 1/2-inch inverted flare outlet for easy replacement. Millivolt control input range: Operates from 350 mV to 850 mV (open circuit) for reliable signal compatibility. Broad environmental tolerance: Functions in ambient temperatures from 32°F to 150°F with storage capability down to -40°F. High humidity resistance: Operates in up to 95% non-condensing humidity at 104°F for dependable performance. Upright installation requirement: Designed for vertical mounting to ensure accurate sensor operation. The WV8840A1050 delivers the reliability and precision required for safe, efficient, and long-lasting water heater operation in standing pilot systems.
