  • 【Widely compatible】WT8840A1000 gas water heater standing pilot control valve is compatible with Honeywell models WV8840A1000, WV8840A1001, and Bradford White models 415-52907-01 and 22-47463-01C. WT8840A1000 compatible with A.O. Smith, for State, for and Reliance, water heaters from other brands such as.
  • 【Precise Temperature Control】 The WT8840A1000 utilizes an advanced thermistor. This electronic sensor is extremely sensitive to changes in water temperature, capable of detecting subtle fluctuations as small as 0.1°F in real time, thus triggering ignition and shut-off commands sooner. This ensures that the water temperature remains constant while the user is using hot water, preventing sudden temperature changes.
  • 【Automatic Shutoff】When the water tank overheats, the internal TCO system automatically shuts off the gas supply. Unlike older, single-use valves, this valve's ECO can be reset, eliminating the need to replace the entire valve after an overheating event. In addition, an advanced NTC temperature sensor and anti-scald algorithm have been added.
  • 【Plug and play】The WT8840A1000/U is an upgraded version of the WV8840A1000 series, designed specifically for water storage tanks with 1-inch insulation. It is fully compatible with the older series and can be directly replaced without modifying existing pipes or brackets. Please refer to the user manual or relevant videos for detailed installation instructions.
  • 【High-end materials】The heavy-duty cast aluminum valve body is resistant to deformation, and the solenoid valve features a reinforced design, boasting a cycle life of up to 150,000 cycles. WT8840A1000 1-inch sensing probe (Spud) has a specially treated surface to reduce the accumulation of limescale (calcium carbonate). This not only extends the sensor's lifespan but also ensures efficient heat transfer, preventing temperature sensing malfunctions caused by limescale buildup.
  • 【Intelligent LED Status Indicator】When the WT8840A1000 Upgraded Water Heater Gas Standing Pilot Control Valve is not operating correctly, the LED light will flash a specific code. This allows maintenance personnel to quickly identify the root cause of the problem and effectively prevent potential hazards.
  • 【Professional after-sales service】If you encounter any dissatisfaction after purchasing our products, please feel free to contact us. We will resolve your issues quickly and efficiently to ensure you have a positive shopping experience.
