The Taco Comfort Solutions 5000 Series ASSE 1017 Certification Thermostatic Mixing Valve delivers point-of-source temperature control for domestic hot water distribution systems and hydronic heating loops. Engineered to blend hot water from the boiler or water heater with cold utility water, this premium valve provides a stable, tempered output that prevents thermal shocking and scalding while allowing high-temperature storage to eliminate Legionella bacteria growth.

Advanced Thermal & Safety Engineering:

  • ASSE 1017 Point-of-Source Safety: Extensively tested and certified to ASSE 1017 standards for domestic water distribution systems, ensuring rapid fail-safe shut-off of the hot water supply if the cold water line drops pressure or fails completely.
  • High-Flow, Low Head-Loss Design: Features an optimized internal port geometry that yields an exceptional Cv rating, minimizing system pressure drop and maintaining maximum volumetric flow rates across complex, multi-fixture residential and commercial plumbing grids.
  • Lockable Tamper-Resistant Dial: Equipped with an adjustable, multi-turn top selector knob that features an integrated mechanical locking pin. This allows installers to precisely calibrate the output temperature gradient and lock it in place to prevent unauthorized adjustment.

Material and Fluid Compliance: Fabricated from low-lead forged brass conforming to strict NSF 61 and NSF 372 drinking water safety standards. Features dual internal check valves on the hot and cold inlets to eliminate cross-contamination or thermal migration back into cold supply lines.
