Why Buy From Us
Every quote personally reviewed. Direct sourcing from top manufacturers.
The Watts LFN170-M1 is a high-capacity, institutional-grade thermostatic master mixing valve engineered to regulate water temperatures in centralized domestic hot water distribution infrastructure. Outfitted with an advanced chemical-resistant wax hydraulic motor, this master valve automatically blends scalding water-heater tank supply with cold domestic lines, ensuring safe, consistent, delivery-controlled temperatures out to point-of-use fixtures.
Safety Engineering & Anti-Scald Technology:
- Thermal Actuator Precision: Houses an incredibly fast-acting thermal element that continually adjusts the hot/cold intake ratio. If the cold water supply fails unexpectedly, the valve automatically cuts off the hot water flow entirely to completely eliminate scalding risks.
- Lead-Free Brass Framework: Forged from a premium lead-free brass alloy core, fully satisfying all municipal potable plumbing infrastructure mandates and drinking water safety standards.
- Tamper-Proof Temperature Lockout: Features a protective hex-wrench locking mechanism located under the cap, allowing facility managers or mechanical contractors to dial in and seal a maximum hot temperature limit.
System Scalding Prevention Notice: Perfect for schools, hospitals, multi-family apartment complexes, and hotels. It allows boiler storage tanks to be safely held at bacteria-killing temperatures above 140°F (60°C) while ensuring safe water delivery at the faucet.
