HFT36001Z-01 Thermostatic Valve, G1/2
The Legom HFT36001Z-01 Thermostatic Valve is a compact G1/2 thermostatic mixing valve with a green ABS handwheel, natural color pickled movable inlet and outlet joints, and a 57-3 copper body — the smallest connection size in the Legom HFT green movable joint series. Movable joints at all connection points allow the valve to accommodate offset or misaligned supply pipework in compact domestic and point-of-use installations, while the natural color pickling provides a clean, oxide-free natural brass surface on the joint connection areas without an applied plating layer.
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 available for OEM orders.
Key Benefits
- Green handwheel at the smallest domestic TMV size – Brings the color-coding and OEM branding capability of the green handwheel to G1/2 compact and single-fixture installations — the smallest connection size in the HFT green series
- Natural color pickled movable joints at G1/2 – Movable joints with acid-cleaned natural brass surfaces on the connection areas provide installation alignment flexibility and a clean natural finish without plating, suited to compact water heater and point-of-use OEM integration
- Movable inlet and outlet joints – All connection points can be repositioned to meet offset supply pipes without additional fittings, particularly valuable in the tight spaces typical of G1/2 under-sink and point-of-use installations
- G1/2 for compact and single-fixture applications – The smallest HFT green series connection size, suited to individual fixture TMVs and compact domestic water heaters with G1/2 outlets
- ±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 construction 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 outlets – Small electric, instantaneous, and compact solar thermal units where G1/2 is the connection size, the green handwheel suits the product color scheme, and movable joints accommodate variable heater outlet positions
- Single-fixture point-of-use installations – Individual basin, shower, or bath applications at G1/2 where offset supply pipes make movable joints necessary and green color coding or OEM branding is required
- OEM water heater products at G1/2 with green specification – The smallest green handwheel TMV in the Legom range for compact water heater product lines requiring green color-coded components
- Confined under-sink and in-cabinet installations – Where tight spaces make pipe alignment to a fixed-port valve impractical, and the movable joints at the small G1/2 size provide the needed connection flexibility
Installation Notes
- Adjust the movable joints on all connections (H, C, M) to align with the actual pipe positions before tightening
- The pickled joint surfaces are clean and oxide-free — apply thread sealant directly to the natural brass surface
- Tighten all connections fully and evenly after alignment — partial tightening can cause leakage under pressure
- Install isolation valves upstream of both hot and cold inlets
- Install a strainer on the cold inlet to protect the thermostatic cartridge
- The valve performs optimally at 0.1–0.5 MPa
- Check all movable joint connections under operating pressure for leaks before commissioning
- Verify outlet temperature at the fixture with a calibrated thermometer after installation
Frequently Asked Questions
When should I choose the HFT36001Z-01 over the HFT36002Z-01?
Choose the HFT36001Z-01 when the water heater outlet or supply pipework is G1/2 (DN15). Choose the HFT36002Z-01 when the connection is G3/4 (DN20). Both share the green handwheel, natural color pickled movable joints, 57-3 copper body, and identical thermostatic performance — connection size is the only difference.
Why use movable joints at the compact G1/2 size?
G1/2 TMVs are most commonly installed at point-of-use locations — under sinks, in compact bathroom cabinets, and at individual fixture connections — where space is extremely limited and precise pipe alignment to a fixed-port valve body is often impractical. Movable joints allow the connection angles to be adjusted to meet the actual pipe positions in the available space, eliminating the need for additional elbow fittings that would further increase the installation’s space requirement in an already confined location.
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 green handwheel color can be customized to other colors for OEM branding. Contact the Legom team with your requirements.
