• 【Replacement Part Numbers】555-050RP, 555050RP. These zone valve power head replacement parts are precision-designed to directly replace worn or faulty power heads, restoring full heating control functionality without replacing the entire valve body.
• 【Applicable Models】Compatible with 570 Series 570 571 572 573, Compatible with 550 Series 555 556 557. Suitable for 1/2 inch to 1-1/4 inch welded valves, ideal for residential and commercial hydraulic heating systems.
• 【Easy DIY Installation】Zone valve power heads can be easily installed without special tools. Simply turn off the boiler power, note the wiring sequence, remove the old valve head, install the new valve head, and then securely connect the three wires. Your heating system will then be back in operation.
• 【Precision Components】Utilizing thermosensitive wax element thermal drive technology, the wax's thermal expansion and contraction smoothly pushes the sealing piston, achieving vibration-free and zero-motor-noise operation. Combined with a precision return spring component, it is precisely synchronized with the circulation pump, preventing jamming and premature triggering, ensuring leak prevention and extremely low mechanical wear, providing precise zone control for Taco valves.
• 【Rugged and Durable】The housing is made of corrosion-resistant aluminum alloy, temperature-resistant and wear-resistant, suitable for a wide operating temperature range of 40°F-240°F. The thermosensitive design ensures silent and leak-free operation within the temperature range of 40°F to 240°F. If you have any questions, please contact us for the most professional advice.
