HFT40006H-01 Thermostatic Mixing Valve, G3/4
The Legom HFT40006H-01 Thermostatic Mixing Valve is a G3/4 thermostatic mixing valve with an electroplated handwheel and external water inlet and outlet connectors, delivering standard HFT thermostatic mixing performance — temperature adjustment range 20–60°C, control accuracy ±2°C, working pressure range 0.03–1 MPa — with a premium metallic handwheel finish and external connector design suited to OEM water heater integration and premium installation environments.
Manufactured from 57-3 copper, the HFT40006H-01 sits alongside the HFT40007H-01 in the Legom electroplated handwheel series at the same G3/4 connection size. Compatible with hot water inlet 30–99°C and cold water inlet 5–29°C, covering all standard domestic water heater types. For specific dimensional differences between the HFT40006H-01 and HFT40007H-01, contact the Legom team or refer to the product datasheets for both models.
Key Benefits
- Electroplated handwheel — premium metallic finish – Metallic surface coating applied by electroplating over the ABS handwheel substrate, providing the appearance and surface hardness of a metal component — significantly more premium than standard silk-screen or plain plastic handwheels across the HFT range
- External water inlet and outlet connectors – Connection flexibility at both inlet and outlet ports, accommodating pipework that does not align precisely with standard fixed-port valve body positions and simplifying OEM water heater assembly integration
- G3/4 — standard domestic connection – Direct compatibility with standard domestic storage water heater outlets and G3/4 supply pipework
- ±2°C temperature control accuracy – Consistent mixed water delivery within ±2°C of the set point
- 20–60°C adjustment range – Full-range commissioning flexibility with factory-preset narrower ranges available
- No electricity required – Self-acting thermostatic operation requiring no electrical connection
- 57-3 copper body – Durable copper alloy construction for potable hot water service
- Wide pressure range 0.03–1 MPa – Covers gravity-fed through mains-pressure systems

Application & Use Cases
- Premium OEM water heater products – The electroplated handwheel provides a premium visual finish for high-tier water heater product lines where component appearance is a quality differentiator
- Visible and semi-exposed installation environments – Where the metallic handwheel finish coordinates with premium plumbing fittings and visible installation aesthetics
- Standard domestic water heater installations requiring premium finish – Compatible with all G3/4 domestic electric, gas, solar thermal, and heat pump water heaters
- Installations requiring external connector positioning flexibility – Where supply or distribution pipework positions require external connectors to bridge alignment differences at the valve body
Installation Notes
- Connect hot water supply to the hot inlet via the external inlet connector (H), cold water to cold inlet (C), and distribution pipework to the external outlet connector (M) using appropriate thread sealant
- Install isolation valves upstream of both hot and cold inlets
- Install a strainer on the cold inlet to protect the thermostatic cartridge
- Handle the electroplated handwheel carefully — avoid contact with thread sealant or pipe compounds on the handwheel surface
- The valve performs optimally at 0.1–0.5 MPa
- Verify outlet temperature at the furthest fixture with a calibrated thermometer after installation
- Flush supply lines before installation to remove debris
Frequently Asked Questions
What is the difference between the HFT40006H-01 and HFT40007H-01?
Both models share the same G3/4 connection, electroplated handwheel, external inlet and outlet connectors, 57-3 copper body, and full thermostatic performance specifications. The difference lies in body geometry, external connector positioning, or dimensional configuration that is not captured in the published specification data. To select the correct model for a specific installation or OEM integration, request dimensional drawings for both models from the Legom technical team and compare against your installation requirements.
What is an electroplated handwheel?
Electroplating deposits a thin metallic coating onto the ABS plastic handwheel through an electrochemical process, producing a surface that has the appearance and hardness of metal while retaining the light weight and dimensional precision of plastic. The result is significantly more premium in appearance than standard painted, printed, or plain ABS handwheels — comparable in visual quality to metal fittings and fixtures in the same installation environment.
Can the temperature range be factory-preset?
Yes. OEM and project orders can specify factory-preset temperature ranges of 35–55°C, 40–50°C, or 30–60°C. Electroplating finish options including chrome, satin nickel, and gold are available for OEM specification. Contact the Legom team with your requirements.
