Product Overview
This integrated gas proportional valve assembly is the core spare part for tankless instant gas water heaters and wall-mounted boilers. It combines dual safety solenoid valves and proportional flow control valve in one aluminum housing, responsible for gas switch and real-time firepower adjustment. When users turn on hot water tap, the sensor transmits water flow signal to the valve, the solenoid opens gas channel, and the proportional module automatically adjust gas volume to maintain constant water temperature. Dual electromagnetic lock design ensures gas will be cut off immediately once equipment power off or abnormal shutdown, effectively avoid dangerous gas leakage. It comes with matched quick plug wire terminals for simple DIY replacement, widely used as aftermarket repair parts for residential gas heating equipment.
Main Advantages
Integrated Heavy-duty Aluminum Valve Body
Integral die-cast aluminum structure strengthens pressure resistance and sealing performance, resist corrosion from gas impurities, no air leakage after long-term use.
Double Solenoid Safety Interlock System
Two independent safety valves form double protection, effectively prevent gas escaping caused by single coil failure, greatly improve household gas safety factor.
Intelligent Constant Temperature Gas Regulation
Precise proportional gas flow control technology automatically match gas supply with water flow speed, avoid sudden hot or cold water during shower, provide comfortable constant temperature bathing experience.
Easy & Fast Installation Replacement
Standard universal pipeline interface and pre-installed quick plug wire connectors, technicians can finish replacement within minutes without extra soldering tools.
Wide Compatibility for Gas Types
Customizable internal spool structure for Natural Gas or LPG Propane, suitable for different regional gas supply environments worldwide.
Installation Notes
Confirm the gas type (Natural Gas / LPG) matches the valve before installation, do not mix use different gas valves.
Check all gas pipe joints with soapy water after installation to test for air leakage.
Ensure wire plugs are fully inserted and locked to avoid poor contact leading to temperature control failure.
This valve is only suitable for household low-pressure gas water heater, not for industrial high-pressure gas equipment.
