HFT33006Z-01 Thermostatic Mixing Valve, G1/2
The Legom HFT33006Z-01 Thermostatic Mixing Valve is a G1/2 thermostatic mixing valve with a fully electroplated body and electroplated handwheel and an external water inlet connector — providing premium metallic surface treatment throughout the valve assembly with supply-side connection flexibility while the mixed water outlet remains a standard fixed port. Temperature adjustment range 20–60°C, control accuracy ±2°C, working pressure range 0.03–1 MPa, compatible with hot water inlet 30–99°C and cold water inlet 5–29°C.
Manufactured from 57-3 copper with full electroplating, the HFT33006Z-01 is the premium-finish counterpart to the HFT33020Z-01, combining the same external inlet connector configuration with a fully electroplated body and handwheel suited to premium OEM water heater products and visible compact installations. Factory-preset temperature ranges available for OEM orders.
Key Benefits
- Full electroplating on body and handwheel – Premium metallic surface treatment throughout both the 57-3 copper body and the ABS handwheel — the highest finish specification available at the G1/2 external inlet connector configuration
- External inlet connector — supply-side flexibility with fixed outlet – External connector on the hot and cold water inlets provides positioning flexibility at the supply connections, while the standard fixed mixed outlet port connects directly to fixed downstream distribution pipework. This is the correct choice when only the supply side requires external connector reach
- G1/2 for compact and point-of-use applications – Smallest standard domestic TMV connection size, suited to single-fixture applications, compact water heaters, and OEM G1/2 product integration
- ±2°C temperature control accuracy – Consistent mixed water delivery within ±2°C of the set point
- 20–60°C adjustment range – Full-range flexibility with factory-preset narrower ranges available
- No electricity required – Self-acting thermostatic operation with no electrical connection needed
- 57-3 copper with full electroplating – Premium construction for durable potable hot water service
- Wide pressure range 0.03–1 MPa – Including low-pressure gravity-fed systems

Application & Use Cases
- Premium OEM compact water heater products at G1/2 – Where the manufacturer specifies full electroplated TMV components for consistent premium metallic appearance and requires external inlet connectors to bridge offset supply connections in the heater assembly
- Visible compact installations requiring premium finish – Under-sink, in-cabinet, and point-of-use locations where the fully electroplated body and handwheel coordinate with premium plumbing fixtures and the external inlet connector accommodates offset supply pipework
- Compact domestic water heaters with offset G1/2 supply connections – Small electric, instantaneous, and compact solar thermal units where the premium electroplated finish is required alongside inlet connector flexibility
- Premium retrofit installations – Replacing an existing G1/2 TMV where supply pipes do not align with the replacement valve’s fixed ports and the new installation specifies fully electroplated components
Installation Notes
- Connect hot and cold supply pipework to the external inlet connectors (H and C) using appropriate thread sealant
- Connect distribution pipework to the standard fixed mixed outlet port (M) using male G1/2 fittings with 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 body and handwheel carefully — avoid contact with thread sealant or pipe compounds on electroplated surfaces
- 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
What is the difference between the HFT33006Z-01 and the HFT33020Z-01?
Both are G1/2 thermostatic mixing valves with external water inlet connectors and identical thermostatic performance. The difference is entirely in finish specification. The HFT33020Z-01 has a surface-plated copper body with a plain black ABS handwheel — the standard finish option. The HFT33006Z-01 has a fully electroplated body and electroplated handwheel — the premium finish option. Choose the HFT33006Z-01 when both the body and handwheel must carry the premium metallic electroplated finish. Choose the HFT33020Z-01 for standard OEM integration where the surface-plated body and plain handwheel are acceptable.
Why does this model have an external inlet connector but a fixed outlet port?
The external inlet connector provides positional flexibility specifically at the supply side — where offset or misaligned hot and cold water supply pipes need to reach the valve’s inlet connections without additional fittings. The mixed water outlet, by contrast, typically connects to fixed downstream distribution pipework at a standard position that does not require external connector flexibility. This inlet-only connector configuration suits installations where supply-side flexibility is needed but the outlet distribution connection is already in a fixed accessible position.
Can the temperature range be factory-preset?
Yes. OEM orders can specify factory-preset temperature ranges of 35–55°C, 40–50°C, or 30–60°C. Electroplating color and finish options are available for OEM specification. Contact the Legom team with your requirements.
