HFT33003Z-01 Thermostatic Mixing Valve
The Legom HFT33003Z-01 Thermostatic Mixing Valve is a G1/2 thermostatic mixing valve with an electroplated handwheel, a surface-plated 57-3 copper body, and an integrated water inlet and outlet connector — combining a premium metallic handwheel finish with integrated connections at both supply and distribution ports, at a standard body plating specification. 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.
The electroplated handwheel provides a premium metallic finish at the point of user contact, while the surface-plated body maintains standard corrosion protection at the valve body — a cost-effective specification option compared to the fully electroplated HFT33008Z-01 when the body finish is not a primary specification requirement. Manufactured from 57-3 copper with surface plating. Factory-preset temperature ranges available for OEM orders.
Key Benefits
- Electroplated handwheel with surface-plated body – Premium metallic electroplating on the handwheel provides a high-specification finish at the user-contact point while the standard surface-plated body provides adequate corrosion protection — a balanced specification for OEM products where handwheel appearance is a primary requirement but full body electroplating is not specified
- Integrated water inlet and outlet connector – Both the supply inlet and mixed outlet connections are integrated into the valve body, reducing external fitting count at both connection points and creating a compact self-contained assembly for OEM integration and confined-space installations
- G1/2 for compact and point-of-use applications – Smallest standard domestic connection size, suited to individual fixture, compact water heater, 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 surface plating – Durable copper alloy with standard protective plating for potable hot water service
- Wide pressure range 0.03–1 MPa – Including low-pressure gravity-fed systems

Application & Use Cases
- OEM compact water heater products requiring electroplated handwheel at standard body finish – Where the OEM specification calls for an electroplated handwheel — for a premium user-contact surface — but does not require full body electroplating, the HFT33003Z-01 provides the correct combination at G1/2
- Compact domestic water heater installations at G1/2 – Small electric, instantaneous, and compact solar thermal units where integrated connectors simplify the valve-to-heater connection and the electroplated handwheel provides a premium appearance at the temperature adjustment point
- Single-fixture point-of-use applications – Individual basin, shower, or bath TMV at G1/2 where integrated connectors reduce the connection fitting count in tight under-sink or in-cabinet locations
- Cost-optimized premium handwheel OEM specification – When the OEM product specifies electroplated handwheel appearance but standard surface-plated body finish — achieving premium user-contact aesthetics at a lower specification cost than full body electroplating
Installation Notes
- Connect hot and cold supply to the integrated inlet connectors (H and C) and distribution to the integrated mixed outlet connector (M) using appropriate G1/2 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 on the electroplated surface
- 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 HFT33003Z-01 and the HFT33008Z-01?
Both are G1/2 thermostatic mixing valves with electroplated handwheels and integrated inlet and outlet connectors — identical thermostatic performance and connection configuration. The difference is the body finish. The HFT33003Z-01 has standard surface plating on the 57-3 copper body — the handwheel is electroplated but the body is not. The HFT33008Z-01 has full electroplating on both the body and the handwheel, providing a consistent premium metallic appearance throughout the entire assembly. Choose the HFT33003Z-01 when the body finish is not a primary specification requirement and only the handwheel needs the electroplated finish. Choose the HFT33008Z-01 when full body and handwheel electroplating is required for a unified premium appearance.
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.
What maintenance does the HFT33003Z-01 require?
The thermostatic cartridge should be inspected annually. Clean the cold inlet strainer periodically depending on local water quality. In hard water areas, cartridge descaling may be required annually. Contact the Legom team for cartridge replacement specifications for the G1/2 model.
