HFT33002Z-01 Thermostatic Diverter Valve, G3/4
The Legom HFT33002Z-01 Thermostatic Diverter Valve is a G3/4 thermostatic mixing valve with a blue ABS handwheel, integrated water inlet and outlet joint, and a bottom inlet, side outlet configuration — combining the distinctive blue handwheel color with the diverter valve geometry suited to water heater installations where supply connections enter from the bottom and the mixed water outlet exits from the side. Manufactured from 57-3 copper, the HFT33002Z-01 delivers standard HFT thermostatic mixing performance — temperature adjustment range 20–60°C, control accuracy ±2°C, working pressure range 0.03–1 MPa.
The blue handwheel is unique in the Legom HFT diverter valve range, suited to OEM water heater products with blue color branding or installations where blue color coding identifies a specific temperature circuit or system function. Compatible with hot water inlet 30–99°C and cold water inlet 5–29°C. Factory-preset temperature ranges available for OEM orders.
Key Benefits
- Blue handwheel — distinctive color identification – The blue ABS handwheel provides immediate visual identification in multi-valve installations and suits OEM water heater products with blue brand color schemes. Blue is used in many plumbing color-coding systems to indicate cold water circuits, specific temperature zones, or distinct system functions — making it a meaningful visual specification beyond aesthetics alone at the standard domestic G3/4 diverter valve size
- Bottom inlet, side outlet diverter geometry – Hot and cold supply connections enter from the bottom through the integrated joint while the mixed water outlet exits from the side, matching water heater installations where vertical supply risers and horizontal distribution pipework meet at the mixing point without requiring additional elbow fittings
- Integrated water inlet and outlet joint – Both inlet and outlet connections are integrated into the valve body, reducing external fitting count at the connection point and creating a compact self-contained mixing assembly for OEM water heater integration
- G3/4 — standard domestic water heater connection – The most common domestic TMV connection size, compatible with standard domestic storage water heater outlets and G3/4 pipework
- ±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 body – Durable copper alloy for potable hot water service
- Wide pressure range 0.03–1 MPa – Covers gravity-fed through standard mains-pressure systems

Application & Use Cases
- OEM water heater products with blue color branding – Manufacturers whose product color scheme uses blue as a primary or accent color, enabling the TMV handwheel to coordinate with the heater’s overall product appearance at the standard domestic G3/4 diverter connection size
- Color-coded multi-valve installations – Where blue handwheel color distinguishes this valve’s circuit function from other valves (green, black, white) in the same installation, enabling rapid identification without reading labels
- Domestic water heaters with vertical supply and horizontal distribution – Where hot and cold supply risers approach from below and the mixed distribution pipe exits horizontally — the most common layout in wall-hung domestic water heater installations — matching the bottom inlet, side outlet geometry
- OEM compact water heater assemblies – Where the bottom inlet, side outlet integrated joint geometry and blue handwheel match the heater’s internal connection layout and product color scheme simultaneously
- All standard domestic water heater types – 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 bottom integrated inlet joint — connections enter from below the valve body
- Connect distribution pipework to the side integrated mixed outlet joint (M) using appropriate G3/4 thread sealant
- Plan pipework to align with the bottom inlet and side outlet geometry before installation — the integrated joint orientation is fixed once connected
- Install isolation valves upstream of both hot and cold supply lines
- 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 furthest fixture with a calibrated thermometer after installation
Frequently Asked Questions
How does the HFT33002Z-01 differ from the HFT40014Z-01?
Both are G3/4 thermostatic diverter valves with bottom inlet and side outlet geometry. The HFT40014Z-01 has a standard plain black handwheel, while the HFT33002Z-01 has a distinctive blue handwheel. Additionally, the joint types may differ in specific configuration details. Both serve the same installation geometry and thermostatic function — the blue handwheel is the primary differentiator for OEM color specification and color-coding applications.
Why is the handwheel blue?
Blue is a standard color in plumbing color-coding systems — commonly used to indicate cold water circuits, specific temperature thresholds, or distinct system functions in multi-valve installations. It is also used by water heater manufacturers as a brand accent color. The HFT33002Z-01 is currently the only model in the standard Legom HFT diverter valve range with a blue handwheel, making it a specific specification option for blue-branded OEM products and color-coded installations.
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. The blue handwheel color can also be customized to other colors for OEM branding. Contact the Legom team with your requirements.
