Wax Thermostatic Element LG0829

• Five-stage stroke profile with deceleration zone – Sequential and overlapping stroke specifications across 15°C~38°C, 38°C~45°C, 35°C~45°C, 45°C~60°C, and 15°C~90°C provide detailed actuation data including a deliberate reduced-stroke zone above 45°C
• Early ambient activation from 15°C – Begins responding near ambient temperature, making it suitable for applications requiring thermostatic actuation before the fluid reaches mid-range temperatures
• Deceleration zone at 45°C~60°C – Reduced stroke of 0.86mm in this band creates a deliberate slowdown in piston travel above 45°C, enabling staged valve behavior at temperatures associated with hot water delivery and anti-scald thresholds
• Standard 140N load platform – Compatible with the full range of valve assemblies designed for standard Legom wax elements, without the mechanical constraints of the light-duty 90N models
• Patented wax formula – Proprietary Legom formulation delivers superior sensitivity and temperature-response accuracy versus standard wax elements
• ACS and WRAS certified – Passed European experimental institution product certification, confirming suitability for potable water and HVAC applications in international markets
• Rated for 100,000 cycles – Exceptional service life verified through rigorous lifecycle testing, ensuring reliable long-term performance in high-use installations
• Copper construction – Corrosion-resistant material ensures long-term durability in wet and thermally cycled environments
• OEM and ODM customization available – Temperature range, working stroke, and maximum load can be customized to suit specific product requirements

Temperature vs. Stroke

Stroke values measured during heating-up cycle. Cooling-down cycle may exhibit slight hysteresis typical of wax thermostatic elements. Refer to the Temperature VS. Stroke curve in the Datasheet for the full graphical representation.

• Thermostatic mixing valves (TMV) – The wide initial actuation band from 15°C and the deceleration zone above 45°C make the LG0829 suited for TMV designs requiring graduated valve opening from near-ambient through anti-scald temperatures
• Anti-scald and hot water safety devices – The natural slowdown in piston travel between 45°C and 60°C aligns with standard safe hot water delivery thresholds, enabling safer blended water output as temperatures approach scalding range
• HVAC zone control assemblies – Used in thermostatic control valves where a staged actuation profile is preferred over a simple linear opening characteristic across the full comfort and elevated temperature range
• Automotive engine cooling systems – Applied in engine thermostats requiring graduated actuation beginning from near-ambient cold-start temperatures through normal operating range
• Sanitary and medical equipment – Integrated into thermostatic valve assemblies in hospital and clinical settings where staged temperature control from ambient through hot water delivery temperatures is required
• Plumbing, shipping, military, and other industries – Suitable for any application requiring self-acting, multi-stage thermostatic control across a broad temperature span without electrical dependency

• The LG0829 must be installed in direct contact with the fluid whose temperature it is intended to sense, ensuring accurate thermostatic response across all five stages of the stroke profile
• Ensure the element is fully immersed in the flow path within the host valve or assembly to prevent slow or inaccurate actuation, particularly important given the closely spaced stage boundaries around 35°C~45°C
• Do not expose the element to temperatures exceeding 90°C, as sustained exposure above the maximum rated temperature may permanently degrade the wax charge and reduce stroke accuracy
• Avoid applying forces exceeding the maximum load of 140N to the piston during assembly or operation
• The host valve or actuator assembly must provide adequate spring-back force to reset the piston on cooling, as the wax element generates push force only during heating
• Keep the element away from external heat sources not part of the intended sensing medium to avoid premature actuation across any of the five stroke stages
• For OEM integration, confirm three key parameters in writing before finalizing the order: temperature range, working stroke, and maximum load
