HFT40008Z-01 Thermostatic Mixing Valve, G1/2
The Legom HFT40008Z-01 Thermostatic Mixing Valve is a compact G1/2 thermostatic mixing valve with a spark pattern silk-screen handwheel and nickel-plated 57-3 copper body — the smallest connection size in the Legom HFT spark pattern series. Delivering the same thermostatic mixing performance as the wider HFT range — temperature adjustment range 20–60°C, control accuracy ±2°C, working pressure range 0.03–1 MPa — the HFT40008Z-01 brings the distinctive spark pattern finish to G1/2 single-fixture and compact water heater applications.
Manufactured from 57-3 copper with nickel plating, compatible with hot water inlet 30–99°C and cold water inlet 5–29°C. Factory-preset temperature ranges available for OEM orders requiring restricted operator adjustment.
Key Benefits
- Spark pattern silk-screen at the smallest domestic TMV size – Brings the distinctive spark pattern graphic handwheel finish to G1/2 (DN15) installations, suited to compact point-of-use applications and small water heaters where OEM product differentiation or premium appearance is required at the most compact connection size
- Nickel-plated copper body – Consistent corrosion-resistant silver-toned finish coordinating with the spark pattern handwheel for a unified premium appearance
- G1/2 for compact and single-fixture installations – The smallest HFT connection size, suited to individual fixture point-of-use applications and small domestic water heaters where G3/4 connections are not required
- ±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 with no electrical connection needed
- 57-3 copper with nickel plating – Premium construction for durable potable hot water service
- Wide pressure range 0.03–1 MPa – Including low-pressure gravity-fed systems from 0.03 MPa

Application & Use Cases
- Single-fixture point-of-use installations – Individual basin, shower, or bath TMV where G1/2 is the standard connection size and a premium handwheel finish is part of the product specification
- Compact domestic water heaters with G1/2 outlets – Small electric storage, instantaneous, and compact solar thermal units where the spark pattern finish elevates the product’s appearance
- OEM water heater product integration at G1/2 – Manufacturers requiring a distinctive handwheel graphic for product differentiation at the smallest standard domestic TMV connection size
- Premium domestic hot water installations – Where the homeowner or developer specifies a consistent premium appearance across visible plumbing components including the TMV
Installation Notes
- Connect hot water to hot inlet (H), cold water to cold inlet (C), and mixed outlet (M) to fixture supply using male G1/2 fittings with 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
- The valve performs optimally at 0.1–0.5 MPa
- Verify outlet temperature at the fixture with a calibrated thermometer after installation
- Flush supply lines before installation to remove debris
Frequently Asked Questions
When should I choose the HFT40008Z-01 over the HFT40009Z-01?
Choose the HFT40008Z-01 when the water heater outlet or supply pipework is G1/2 (DN15). Choose the HFT40009Z-01 when the connection is G3/4 (DN20). Both have identical spark pattern handwheels, nickel-plated bodies, and thermostatic performance — connection size is the only difference. G1/2 suits compact heaters and single-fixture point-of-use applications; G3/4 is standard for most domestic storage water heaters.
Can the handwheel graphic be customized for OEM orders?
Yes. The spark pattern can be replaced with a custom OEM logo, graphic, or color specification. Contact the Legom team with your OEM handwheel design requirements.
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. Contact the Legom team to specify the required preset range when ordering.
