HFT33005Z-01 Thermostatic Mixing Valve
The Legom HFT33005Z-01 Thermostatic Mixing Valve is a G1/2 thermostatic mixing valve with an electroplated tip handwheel, an electroplated integrated water inlet joint, and a bundled filter accessory bag — the only model in the Legom HFT range that includes a filter accessory with the valve. The electroplated tip handwheel features metallic plating on the tip section of the handwheel rather than across the full surface, providing a distinctive two-tone appearance that combines the premium metallic accent with a standard ABS body finish.
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. Factory-preset temperature ranges available for OEM orders.
Key Benefits
- Bundled filter accessory bag — ready-to-install package – The filter accessory bag is included with the valve, providing the filtration component needed to protect the thermostatic cartridge from grit and debris at the cold water inlet without requiring a separate filter purchase. This makes the HFT33005Z-01 a more complete installation package than other HFT models that require a separately sourced strainer
- Electroplated tip handwheel — distinctive two-tone finish – Metallic electroplating applied only to the tip section of the handwheel creates a distinctive accent finish that differs from both fully electroplated and standard plain handwheels. The tip electroplating provides a premium visual accent while maintaining the standard handwheel ABS body, suited to OEM products with specific design language requirements
- Electroplated integrated water inlet joint – Premium metallic finish on the integrated inlet connection, reducing external fitting count at the supply connection points while maintaining a consistent electroplated appearance at the inlet
- G1/2 — compact and single-fixture size – Smallest standard domestic connection size, suited to individual fixture, compact water heater, and OEM G1/2 product integration applications
- ±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 body – Durable copper alloy for potable hot water service
- Wide pressure range 0.03–1 MPa – Including low-pressure gravity-fed systems

Application & Use Cases
- OEM water heater products with bundled filter specification – Manufacturers who include a filter accessory with their TMV component as part of a complete installation kit can specify the HFT33005Z-01 to receive valve and filter in a single OEM supply, simplifying assembly and reducing component sourcing complexity
- Compact domestic water heater installations – G1/2 applications where having the filter accessory included with the valve eliminates a separate procurement step and ensures the correct filter specification is always paired with the valve
- OEM products requiring electroplated tip handwheel design language – Manufacturers whose product design specifies a two-tone handwheel with metallic tip accent rather than a fully electroplated or plain handwheel, as a distinct design element in their product line
- Single-fixture point-of-use installations – Individual basin, shower, or bath TMV applications at G1/2 where the bundled filter simplifies the complete installation package
Installation Notes
- Install the bundled filter accessory on the cold water inlet connection before connecting the supply pipe — the filter protects the thermostatic cartridge from grit and debris that would otherwise require periodic strainer cleaning from a separately installed inline strainer
- Connect hot water supply to the hot inlet via the electroplated integrated inlet joint (H), cold water to the filtered cold inlet (C), and distribution to the mixed outlet (M) using appropriate thread sealant
- Install isolation valves upstream of both hot and cold inlets to enable filter cleaning and valve servicing without system shutdown
- The bundled filter accessory bag requires periodic cleaning — inspect and clean according to local water quality conditions, typically every 6–12 months in standard mains water supply
- 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 an electroplated tip handwheel?
An electroplated tip handwheel has metallic electroplating applied only to the tip — the outer edge or top surface — of the ABS handwheel, rather than across the full handwheel surface as on fully electroplated models. This creates a two-tone appearance with a metallic accent at the tip and a standard ABS finish on the body of the handwheel. The tip electroplating provides a premium visual accent and a tactile metallic feel at the point of contact when adjusting the valve, while using less electroplating than a fully electroplated handwheel. This is a distinct design specification from both plain ABS handwheels and fully electroplated handwheels.
What does the filter accessory bag protect against?
The filter accessory bag is installed at the cold water inlet and captures grit, sand, pipe scale, and other particulate debris carried in the water supply before it reaches the thermostatic cartridge. The thermostatic cartridge contains precision components — the wax element, valve seat, and plug rubber — that can be damaged or jammed by grit particles, causing the valve to malfunction or lose temperature accuracy. Regular cleaning of the filter bag maintains correct flow through the cold inlet and protects the cartridge from premature wear. This is the same protective function as a separately installed inline strainer, bundled into the valve package.
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 filter accessory bag specification and electroplated tip handwheel design can also be customized for OEM requirements. Contact the Legom team with your specifications.
