Flow Control Device & Pressure Relief Valve for Gas Water Heaters
Flow Control Device with Pressure Relief Valve for 220V Gas Water Heaters & Wall-Mounted Boilers
Keep your gas water heater or wall-mounted boiler running safely and efficiently with this intelligent Flow Control Device with Pressure Relief Valve. Designed for 220V systems, it monitors water flow in real time, automatically activates or shuts down the heater based on flow status, and features a built-in safety valve to maintain stable system pressure — all in a durable, compact package. Made in Mainland China.
Key Features
- Intelligent Water Flow Monitoring: Precise flow detection ensures your gas water heater or boiler only operates when water is actually flowing, preventing dry-burn situations and extending system lifespan.
- Auto Start/Stop Function: Automatically activates the heating system when flow is detected and shuts it down when flow stops — saving energy and reducing wear on your appliance.
- Built-In Pressure Relief Valve: The integrated safety valve regulates system pressure, protecting your boiler and pipework from over-pressurisation and potential damage.
- Robust, Long-Lasting Construction: Built from durable materials engineered to withstand continuous operation and perform reliably across a wide range of water conditions and environments.
- Wide Compatibility: Designed to fit most standard gas water heaters and wall-mounted gas boiler systems, making it a versatile replacement or upgrade component.
- 220V System Ready: Operates on standard 220V electrical supplies, suitable for residential and light-commercial installations across many regions.

Frequently Asked Questions
Q: What appliances is this flow control device compatible with?
A: This flow control device with pressure relief valve is specifically designed for use with gas water heaters and wall-mounted gas boiler systems that operate on 220V AC supplies. It fits most standard models and is suitable for both residential and light-commercial installations.
Q: How does the pressure relief valve protect my water heater system?
A: The built-in pressure relief valve automatically regulates water pressure within the system. If pressure rises above safe operating levels, the valve activates to release excess pressure, preventing potential damage to the boiler, pipework, or connected components.
Q: Does this device help prevent dry burning in gas water heaters?
A: Yes. The intelligent flow sensor detects whether water is actually flowing through the system before allowing the heater to operate. If no flow is detected, the device signals the heater to remain off, preventing dry-burn conditions and helping to extend the operational life of your appliance.
Q: What is included in the package?
A: Each package includes one flow switch/flow control device and one wiring harness for installation. Please ensure compatibility with your specific gas water heater or boiler model before purchase.
