Siemens Building Technology LFLM490-1 Valve

Siemens Building Technology LFLM490-1 Valve

The Siemens Building Technology LFLM490-1 Valve is a professional-grade 1/2" thermostatic mixing valve engineered specifically for high-efficiency hydronic heating and cooling systems. Built with a heavy-duty lead-free brass body and a durable stainless steel stem, this 3-way mixing valve offers reliable fluid temperature control across a versatile range of 90°F to 160°F. Designed to balance warm and cold streams with precision, it effectively stabilizes mixed water output, minimizing the risk of thermal shock and extending the operational lifespan of downstream HVACR equipment.

For technicians in the field, the LFLM490-1 simplifies maintenance with its union connection design and integrated check valves. These integral check valves are critical for preventing cross-flow and protecting the system from contamination caused by pressure differentials. The valve utilizes an advanced paraffin-based thermal actuator to ensure rapid response to inlet temperature fluctuations, maintaining a steady setpoint even in low-flow conditions. With a solid flow capacity of up to 23 GPM at a 45 PSI differential, this tempering valve is a standard choice for contractors requiring ASSE 1017 certified performance in domestic hot water and radiant heating applications.

Key Benefit List:
  • Precise Temperature Regulation: Maintains a stable outlet temperature between 90°F and 160°F, ideal for radiant floor heating and domestic water tempering.
  • Lead-Free Brass Construction: Ensures compliance with modern plumbing codes and provides high resistance to corrosion in demanding hydronic environments.
  • Integrated Maintenance Features: Features union connections for rapid serviceability and integral checks with screens to filter out system debris.
  • Vandal-Resistant Control: Includes a lockable handle mechanism to prevent unauthorized adjustments and maintain system calibrated setpoints.
  • High Flow Efficiency: Supports mixed water flow rates up to 23 GPM, accommodating multiple fixtures or high-demand heating zones without significant pressure drop.
Common Questions:
  • Can the LFLM490-1 be used for point-of-use anti-scald protection? No, this is a master tempering valve designed for point-of-distribution installation near the water heater or boiler. For individual fixtures, use ASSE 1016, 1069, or 1070 listed devices.
  • Does this valve include check valves to prevent backflow? Yes, it features built-in check valves and thermal actuators to prevent cross-flow between the hot and cold supply lines.
  • Is this mixing valve compatible with PEX or Copper piping? The valve features 1/2" NPT union connections, making it compatible with copper, PEX, or CPVC piping when using the appropriate transition tailpieces.
