Taco Update: New Low Lead Mixing Valve

Latest News > E-mail Newsletters

Featured Product:
New 5120 Series Low Lead Mixing Valve

The new, Low Lead model of Taco's 5120 Series Mixing Valve is manufactured to meet code requirements for exclusively using low lead products in potable water applications. Such regulations were recently passed in California and Vermont and are being considered in a number of other states.

Like the original 5000 Series Mixing Valve, the new Low Lead version is designed for use at the water heater to distribute controlled water temperatures to the domestic hot water system. It allows for domestic hot water storage at temperatures high enough to kill harmful bacteria and that still can be delivered at a safe 120° F. or less.

The high flow, low head loss characteristics of the NSF 61-certified 5120 Series Mixing Valve make it ideal for use in the distribution of water through a domestic hot water system. The valve's unique design and advanced thermostatic element ensures a stable mixed water temperature throughout the valves adjustable range. Features of the Low Lead 5120 Series Valve include:
  • NSF 61-Certified
  • Available sizes: 1/2", 3/4", 1"
  • High Flow
  • Snap-on Protective Cover
  • No Routine Maintenance Required

HVAC Pros Ask...
Question: What is the correct air charge pressure for my captive Air Expansion Tank?

Answer: The air charge pressure should be equal to either the system fill pressure or the Pressure Reducing Valve setting if the tank is at the same elevation as the Pressure Reducing Valve. If the tank is located at any other elevation in the system, the charge pressure in the tank should be the cold pressure of the system at that elevation.
