555-050RP Zone Valve Power Head Compatible with Taco 550 Series & 570 Series (570, 571, 572, 573), 24V Heat-Actuated Actuator, Hydronic Boiler Control, 3-Year Free Replacement
【PERFECT COMPATIBILITY】 Specifically designed for Taco 570 Series (570, 571, 572, 573) and 550 Series (555, 556, 557). This 555-050RP replacement head restores full heating control to your hydronic system without the need to replace the entire valve body.
【5-MINUTE DIY INSTALLATION】 No specialized tools or plumbing skills required. Featuring a simple twist-off/on design and standard 3-wire terminals, you can complete the swap in minutes. Simply record your wiring, twist off the old head, and snap the new one into place.
【SILENT HEAT-ACTUATED TECHNOLOGY】 Upgrade to a quieter home. Our power head uses a heat-responsive wax element instead of a traditional noisy motor. It drives the internal piston smoothly and silently, eliminating vibrations and preventing "water hammer" noise during heating cycles.
【HEAVY-DUTY RELIABILITY】 Built with a corrosion-resistant aluminum housing and tested for 50,000+ heating cycles. It ensures precise zone control and prevents valve sticking in temperatures ranging from 40°F to 240°F.
【3-YEAR WARRANTY】 Buy with confidence. We provide a 36-month free replacement guarantee and 24/7 professional technical support. Engineered for long-term performance in both residential and commercial boiler systems.
