  • Compatibility — Perfect Match for Taco Zone Valves: The 555-050RP zone valve power head replacement is precisely engineered to fit Taco 556 and 570 series zone valves. It serves as a reliable replacement for worn or faulty heads, restoring smooth control and heating performance without the need to replace the entire valve body. Ideal for both residential and commercial hydronic systems using Taco zone valves and boiler control setups for consistent heating performance.
  • Easy Installation — DIY Friendly Setup: Designed for straightforward installation, the 555-050RP power head can be easily mounted without specialized tools. Just shut off boiler power, record wiring order, remove the old valve head, install the new one, and reconnect the three wires securely. You can also watch the installation process on YouTube. Clear instructions and online tutorials make this process simple and fast, even for users with limited HVAC experience.
  • Heat-Actuated Wax Element & Precision Components: The 555-050RP zone valve power head replacement uses a heat-responsive wax element instead of a traditional motor. As the wax expands, it drives the internal piston smoothly to open and close the valve with no vibration or motor noise. This thermal-actuated design provides stable, silent control and reduces mechanical wear. Paired with a sealed piston and return spring assembly, it ensures precise zone control and long-term reliability in Taco valve applications.
  • Reliable Performance and Smooth Control: The 555-050RP replacement head uses a heat-actuated element to provide consistent and quiet valve operation. It keeps the hydronic heating zone balanced and responsive, preventing uneven heating or sticking valve issues. Tested through more than 50,000 heating cycles, it ensures dependable power and control for your Taco-based boiler system.
  • Cost-Effective, Energy-Efficient Replacement Choice: Instead of replacing the entire valve assembly, the 555-050RP power head offers a cost-effective solution that restores full zone control while saving time and labor. Its efficient thermal actuator minimizes energy use and supports stable heating across multiple zones. Perfect for homeowners, technicians, and HVAC professionals who value quality and long-lasting performance.
  • Durable Construction and Technical Parameters: Constructed with an aluminum alloy housing for corrosion resistance, this zone valve head operates on 24 VAC with an isolated end switch and a three-wire connection. The heat-actuated design ensures silent, leak-proof performance from 40°F to 240°F. Engineered for long service life and consistent control, it fits Taco sweat valve assemblies ranging from 1/2" to 1-1/4", offering long-term reliability for professional heating systems.
