HFT33001Z-01 Thermostatic Diverter Valve, G1/2
The Legom HFT33001Z-01 Thermostatic Diverter Valve is a compact G1/2 thermostatic mixing valve with a blue ABS handwheel, integrated water inlet and outlet joint, and a bottom inlet, side outlet configuration — the smallest connection size in the Legom HFT blue diverter valve series. Hot and cold supply connections enter from the bottom through the integrated joint while the mixed water outlet exits from the side, matching compact domestic water heater installations where vertical supply connections and horizontal distribution meet at the mixing point.
Manufactured from 57-3 copper, the HFT33001Z-01 delivers standard HFT thermostatic mixing performance — temperature adjustment range 20–60°C, control accuracy ±2°C, working pressure range 0.03–1 MPa — with the distinctive blue handwheel suited to OEM water heater products with blue color branding and color-coded multi-valve installations. Compatible with hot water inlet 30–99°C and cold water inlet 5–29°C.
Key Benefits
- Blue handwheel at the smallest diverter TMV size – Distinctive blue ABS handwheel for color-coding and OEM blue brand coordination at the most compact G1/2 bottom inlet, side outlet connection size — suited to small domestic water heaters and point-of-use diverter applications
- Bottom inlet, side outlet at G1/2 – Compact diverter geometry accommodating vertical supply and horizontal distribution at the smallest standard domestic TMV connection size, without requiring additional elbow fittings
- Integrated water inlet and outlet joint – Both connections integrated into the valve body, reducing external fitting count and creating a compact self-contained mixing assembly for OEM compact water heater integration
- G1/2 — smallest standard domestic size – Suited to compact domestic water heaters, instantaneous units, and point-of-use applications where G3/4 connections are not specified
- ±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 – Including low-pressure gravity-fed systems

Application & Use Cases
- Compact OEM water heater products with blue color branding at G1/2 – Small water heater units where the blue handwheel coordinates with the product’s color scheme and the bottom inlet, side outlet geometry matches the heater’s internal connection layout
- Compact domestic water heaters with vertical supply at G1/2 – Small electric, instantaneous, and compact solar thermal units where supply approaches from below and distribution exits horizontally at the G1/2 connection size
- Color-coded compact installations – Where blue handwheel color distinguishes this valve’s function or circuit from other valves in the same installation at the most compact diverter size
- Point-of-use diverter applications – Where the bottom inlet, side outlet geometry suits the specific space and pipework layout at a single-fixture connection point
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 G1/2 thread sealant
- Plan pipework to align with the bottom inlet and side outlet geometry before installation
- 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 fixture with a calibrated thermometer after installation
Frequently Asked Questions
When should I choose the HFT33001Z-01 over the HFT33002Z-01?
Choose the HFT33001Z-01 when the water heater outlet or supply pipework is G1/2 (DN15). Choose the HFT33002Z-01 when the connection is G3/4 (DN20). Both share the blue handwheel, bottom inlet side outlet geometry, integrated joint, 57-3 copper body, and identical thermostatic performance — connection size is the only difference.
Why is the handwheel blue?
Blue is a standard color in plumbing color-coding systems and is widely used as a brand color by water heater manufacturers. In multi-valve installations, the blue handwheel distinguishes this valve from black, white, green, or gray alternatives, enabling rapid visual identification of specific circuits or functions without requiring label reading. It is one of only two blue handwheel models in the standard Legom HFT range — both are diverter valves.
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 be customized to other colors for OEM branding. Contact the Legom team with your requirements.
