Powers Commercial 390-809 Actuator

The Powers Commercial 390-809 Actuator is a vital precision component for maintaining accurate discharge temperatures in high-demand mixing valve applications. Engineered specifically as a Standard Range Wax Actuator, this thermal element is the internal driving force for thermostatic mixing valves, ensuring consistent water temperature regulation between 90°F and 160°F. Designed for compatibility with the Powers HydroGuard XP series, this actuator is a direct replacement for models LFMM433, LFMM434, LFSH1434, and their standard non-lead-free counterparts (MM433, MM434, SH1434). Its bronze construction provides robust resistance to scaling and corrosion in potable water systems, meeting ASSE 1017 and CSA B125 standards for safety and performance. For contractors performing preventative maintenance or troubleshooting temperature fluctuations in commercial domestic hot water loops, utilizing a genuine Powers 390-809 thermal element is essential to restore proper thermostatic modulation and protect against scalding or thermal shock.

Key Benefits:

• Compatible with Powers HydroGuard XP LFMM433, LFMM434, and LFSH1434 mixing valve bodies.
• Operating temperature range of 90°F to 160°F for standard domestic hot water applications.
• High-quality bronze material construction ensures long-term reliability in varying water conditions.
• Meets critical industry standards ASSE 1017 and CSA B125 for temperature control valves.
• Direct-fit replacement part simplifies field service and reduces labor time for HVACR technicians.

Common Questions:

What valves are compatible with the Powers 390-809?
This actuator kit is designed for the Powers HydroGuard XP series, specifically mixing valve models LFMM433, LFMM434, LFSH1434, MM433, MM434, and SH1434. It is also a cross-reference for Grainger part numbers 15W076, 15W077, and 26X133.

What is the temperature range for this specific wax actuator?
The Powers 390-809 is a Standard Temp Actuator kit, maintaining a set-point range typically found between 90°F and 160°F, with a maximum operating temperature of 200°F.

How do I know if the actuator needs replacement?
If a mixing valve begins to deliver inconsistent output temperatures or fails to shut down on cold water failure, the internal wax element may be fatigued or compromised by mineral buildup, necessitating a swap with a new 390-809 actuator.
