HFT40013Z-01 Thermostatic Diverter Valve, G1/2
The Legom HFT40013Z-01 Thermostatic Diverter Valve is a compact G1/2 thermostatic mixing valve with an integrated water inlet and outlet connector in a bottom inlet, side outlet configuration — the smallest connection size in the Legom HFT thermostatic diverter valve series. Hot and cold water supplies enter through the integrated bottom inlet connector while the mixed water outlet exits from the side of the body, accommodating compact domestic installations where vertical supply connections and horizontal distribution are required in the tightest available space.
Manufactured from 57-3 copper with surface plating, the HFT40013Z-01 delivers the same thermostatic mixing performance as the wider HFT series: 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. Factory-preset temperature ranges are available for OEM orders.
Key Benefits
- Smallest diverter TMV in the HFT range — G1/2 – Brings the bottom inlet, side outlet integrated connector geometry to the most compact domestic connection size, suited to small water heaters and point-of-use installations where space is the primary constraint
- Integrated bottom inlet connector – Hot and cold supply connections enter from the bottom through an integrated fitting built into the valve body, reducing total fitting count and creating a compact self-contained mixing assembly at the heater connection point
- Side mixed water outlet – Mixed water exits horizontally from the side of the body, matching layouts where the distribution pipe runs perpendicular to the vertical supply connections
- ±2°C temperature control accuracy – Consistent mixed water delivery within ±2°C of the set point across varying supply conditions
- 20–60°C adjustment range – ABS black handwheel with factory-preset narrower ranges available for safety applications
- No electricity required – Self-acting thermostatic operation with no electrical connection needed
- 57-3 copper with surface plating – Durable copper alloy body for potable hot water service
- Wide pressure range 0.03–1 MPa – Including low-pressure gravity-fed systems from 0.03 MPa

Application & Use Cases
- Compact domestic water heaters with G1/2 bottom connections – Small electric storage units, instantaneous heaters, and compact solar thermal systems where G1/2 is the outlet connection size and supply pipes enter vertically from below
- OEM water heater product integration at G1/2 – Water heater manufacturers needing a compact integrated thermostatic mixing assembly at G1/2 for smaller product lines or point-of-use heater units
- Single-fixture point-of-use applications – Where the supply approaches from below and distribution exits horizontally — a common configuration in under-counter instantaneous heater installations
- Space-constrained domestic installations – Where the compact body size of the G1/2 diverter valve and its integrated connector minimise the assembly footprint in tight under-sink or in-cabinet locations
Installation Notes
- Connect hot and cold water supplies to the bottom integrated inlet connector — connections are made directly to the integrated fitting in the valve body base
- Connect distribution pipework to the side mixed outlet (M) using male G1/2 fittings with appropriate thread sealant
- Plan pipework to align with the bottom inlet and side outlet orientations before installation — the fixed integrated connector geometry cannot be rotated once installed
- 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 HFT40013Z-01 over the HFT40014Z-01?
Choose the HFT40013Z-01 when the water heater outlet or supply pipework is G1/2 (DN15). Choose the HFT40014Z-01 when the connection is G3/4 (DN20). Both have identical bottom inlet, side outlet, integrated connector geometry and thermostatic performance — connection size is the only difference. G1/2 suits compact domestic heaters and point-of-use applications; G3/4 is the standard for most domestic storage water heaters.
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. Dimensional drawings and integration specifications are available for OEM projects — contact the Legom team with your complete requirements.
