BA-187 Gas Water Heater Water-Gas Linkage Valve and Ignition Controller Set | Wholesale Supplier

The BA-187 Gas Water Heater Water-Gas Linkage Valve and Ignition Controller Set provides the essential control components for tankless gas water heaters and gas instant heating systems. This set includes the water-gas linkage valve with its distinctive L-shaped structure and white plastic water flow sensor housing, the pulse ignition controller that generates high-voltage sparks for burner ignition, and thermocouple safety devices for flame failure protection.

The water-gas linkage valve is the heart of the gas water heater control system. It features a precision brass alloy body with a white plastic water flow sensor housing that detects the movement of water through the system. When water flows through the heater, the sensor activates the linkage mechanism, which opens the gas valve to allow fuel to the burner. When water stops flowing, the valve automatically closes, shutting off the gas supply. This automatic operation provides both convenience and essential safety.

The pulse ignition controller is a compact black electronic module that generates high-voltage electrical sparks for reliable burner ignition. It functions as a piezo-electric ignition system, producing sparks without the need for external power. When the water-gas linkage valve opens the gas supply, the ignition controller simultaneously produces a spark at the burner electrode, igniting the gas-air mixture. The controller is rated for over 100,000 ignition cycles and operates on standard low-voltage DC power, making it suitable for battery-powered or mains-powered water heater systems.

The thermocouple safety device included in this set provides critical flame failure protection. This copper rod with a metal sensing tip generates a small electrical voltage when heated by the burner flame. This voltage keeps the gas valve open. If the flame is extinguished, the thermocouple cools, the voltage drops, and the gas valve closes automatically, preventing unburned gas from escaping. This safety device is required by regulations in most countries for all gas-burning appliances.

All components are constructed from high-quality materials. The brass alloy valve body provides corrosion resistance and leak-proof operation. The white plastic water flow sensor housing is engineered for reliable water flow detection and long service life. The pulse ignition controller uses durable electronic components sealed in a protective housing. The thermocouple features a stainless steel protective sheath for durability in high-temperature environments.

This set is specifically designed for tankless gas water heaters, gas instant heating systems, and gas-fired boilers operating on LPG, propane, or butane. The components work together as an integrated system, with the water flow sensor, gas valve featuring ON/OFF and OPEN/CLOSE markings, ignition controller, and thermocouple forming a complete control loop. The set is also suitable for replacement and repair of existing water heater systems, making it essential for repair technicians and maintenance professionals.

Each component is certified to CE, RoHS, and REACH standards, ensuring compliance with international safety and environmental requirements. The packing includes 1 piece per blister pack or bag, with 100 pieces per master carton measuring 50x40x30cm, with a gross weight of 12kg and net weight of 9kg.

With a minimum order quantity of 100 pieces and pricing from $1.5 to $6.0 per unit, this set offers excellent value for water heater manufacturers, gas appliance repair shops, plumbing wholesalers, and HVAC technicians. The comprehensive nature of this set simplifies procurement and ensures compatibility between components.
