HFT33004Z-01 Thermostatic Mixing Valve
The Legom HFT33004Z-01 Thermostatic Mixing Valve is a G3/4 thermostatic mixing valve with a fully electroplated body, an electroplated handwheel assembly, and an integrated water inlet and outlet connector — combining full-body premium metallic finish with a multi-component electroplated handwheel assembly and integrated connections at both the supply and distribution ports. 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 assembly — a multi-component electroplated set rather than a single-piece handwheel — provides a more complex visual and mechanical specification than standard single-piece handwheels, suited to premium OEM water heater products where the handwheel is a visible design element requiring a higher-specification component assembly. Manufactured from 57-3 copper with full electroplating. Factory-preset temperature ranges available for OEM orders.
Key Benefits
- Electroplated handwheel assembly — multi-component premium handwheel – Unlike standard single-piece handwheels, the electroplated handwheel assembly is a multi-component set with electroplating throughout, providing a more complex and premium handwheel specification suited to water heater products where the temperature adjustment control is a prominent visible feature requiring premium component quality
- Full electroplating on the valve body – Premium metallic surface treatment on the 57-3 copper body provides consistent high-specification appearance across the entire visible valve assembly, coordinating with the electroplated handwheel assembly for a unified premium finish
- Integrated water inlet and outlet connector – Both the supply inlet and mixed outlet connections are integrated into the valve body assembly, reducing external fitting count at both connection points and creating a compact self-contained thermostatic mixing unit for OEM integration
- G3/4 — standard domestic water heater connection – Direct compatibility with standard domestic storage water heater outlets and G3/4 supply pipework at the most common domestic TMV connection size
- ±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 full electroplating – Premium construction for durable potable hot water service
- Wide pressure range 0.03–1 MPa – Covers gravity-fed through standard mains-pressure systems

Application & Use Cases
- Premium OEM water heater products with handwheel assembly specification – Where the water heater manufacturer’s product design specifies a multi-component electroplated handwheel assembly as the temperature adjustment control element, requiring a higher-complexity handwheel component than a single-piece alternative
- Domestic water heater installations requiring the highest finish specification – The combination of fully electroplated body, electroplated handwheel assembly, and integrated connectors at both inlet and outlet represents the highest available finish and integration specification in the G3/4 TMV range
- Visible installations where the handwheel is a prominent design element – Where the TMV is installed in a customer-visible location and the temperature adjustment handwheel is a prominent part of the product’s visual design, requiring a premium multi-component assembly rather than a standard single-piece handwheel
- All standard domestic water heater types at G3/4 – Compatible with electric, gas, solar thermal, and heat pump water heaters with G3/4 outlet connections
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 G3/4 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 assembly carefully — avoid contact with thread sealant on electroplated surfaces
- 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 a handwheel assembly versus a standard single-piece handwheel?
A standard TMV handwheel is a single molded ABS component — one piece that rotates to adjust the temperature set point. A handwheel assembly is a multi-component set where the handwheel consists of two or more parts — for example, a separate cap, skirt, indicator, or locking ring — assembled together to form the complete handwheel unit. The assembly configuration allows a more complex design with distinct visual elements and functional components, and electroplating the assembly provides premium metallic finish across all components of the set. This is a more complex specification than a single-piece handwheel and is used in premium OEM products where the handwheel design is a key product feature.
How does the HFT33004Z-01 differ from the HFT33007Z-01?
Both are G3/4 thermostatic mixing valves with fully electroplated bodies and electroplated handwheels. The differences are in the handwheel type and connector configuration. The HFT33004Z-01 has a multi-component electroplated handwheel assembly with integrated inlet and outlet connectors — connections are made through built-in integrated fittings at both ports. The HFT33007Z-01 has a single-piece electroplated handwheel with external connectors that extend the connection points outward from the valve body. Choose the HFT33004Z-01 when the handwheel assembly specification and integrated connectors match your OEM or installation requirements. Choose the HFT33007Z-01 when external connector reach is needed at both ports.
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. The handwheel assembly design and electroplating specification can also be customized for OEM branding requirements. Contact the Legom team with your specifications.
