Powers Commercial LFMM432-10 Valve

The Powers Commercial LFMM432-10 is a high-performance HydroGuard XP master tempering valve designed for large-scale hot water distribution systems. This lead-free thermostatic mixing valve utilizes advanced paraffin-based thermal actuation technology to provide precise temperature control with a dynamic response to fluctuations in supply pressure or temperature. Engineered for commercial and institutional environments, the LFMM432-10 features 3/4" FNPT inlets and a 1" FNPT outlet, delivering a flow capacity of up to 64 GPM at a 45 psi pressure drop while maintaining an industry-leading 5°F approach temperature. The ASSE 1017 listed valve includes a single-seat design for positive shutoff in the event of a cold water supply failure and is equipped with rotatable union triple-duty checkstops for simplified maintenance. With an adjustable temperature range of 90°F to 160°F and a vandal-resistant locking mechanism, this commercial mixing valve ensures stable outlet temperatures across varying flow demands, fulfilling CSA B125 compliance requirements for lead-free installations.

• Paraffin-Based Actuation: Provides superior sensitivity and rapid temperature correction compared to standard bimetallic coils.
• High Flow Efficiency: Rated for a 9.49 Cv with a minimum flow rate of 4.0 GPM, ideal for recirculating hot water systems.
• Lead-Free Brass Construction: Fully complies with safe drinking water standards for all commercial potable water applications.
• Integrated Safety Features: Virtual shutoff functionality prevents scalding if the cold water supply is interrupted.
• Contractor-Friendly Installation: Features rotatable union checkstops and screens to protect internal components from debris and liming.

What is the minimum flow required for this valve to operate correctly?
To maintain accurate temperature control according to ASSE 1017 standards, the LFMM432-10 requires a minimum flow rate of 4.0 GPM (15 Lpm). For systems with continuously operating recirculated tempered water, ensure the pump is sized to meet this minimum requirement.

Can the temperature setting be locked to prevent tampering?
Yes, the valve includes a vandal-resistant locking mechanism. Once the desired discharge temperature (between 90°F and 160°F) is reached, the locknut secures the adjustment screw to maintain a consistent output.

Is this valve suitable for "point-of-use" anti-scald protection?
While the LFMM432-10 is a master tempering valve listed to ASSE 1017 for distribution systems, it must be used in conjunction with ASSE 1016, 1069, or 1070 certified devices at the point of use for specific anti-scald requirements at fixtures.
