Apollo Valves 35603bftt Backflow Preventer and Fast Fill Pressure Regulator 1/2 Inches Union Fnpt X Fnpt

Product Description

The Apollo Valves 35603bftt is a combination backflow preventer and fast fill pressure regulator designed for use on residential and commercial hot water heating boilers. This unit protects potable water supply lines from both back-siphonage and backpressure conditions. It serves as a critical safety and performance component in hydronic heating systems, where maintaining clean, uncontaminated water is essential for system health and regulatory compliance. Plumbers, HVAC technicians, and mechanical contractors rely on combination feedwater regulators like the 35603bftt to simplify boiler makeup water connections while meeting code requirements for backflow protection. The 1/2 inches union FNPT x FNPT configuration allows for straightforward installation and removal during service calls, saving time on the job. An intermediate atmospheric vent is built into the design to ensure positive protection against backflow under all conditions. The integrated pressure regulator delivers boiler makeup water at the desired set pressure, keeping the system properly charged without overpressurization. A purge and quick fill feature allows technicians to rapidly fill or purge the heating system during initial startup or after maintenance work, reducing commissioning time. This combination valve eliminates the need to install a separate backflow preventer and pressure reducing valve, cutting down on fittings, labor, and potential leak points. Manufactured by Aalberts integrated piping systems Americas, Inc. under the Apollo brand, this valve is built to handle the demands of boiler feed applications in both new construction and retrofit projects. It is a reliable choice for any hydronic heating system that requires a code-compliant, dual-function feedwater control solution. At 2.25 pounds, it is compact and manageable for tight mechanical room installations.

• Combination backflow preventer and pressure regulator in a single unit for boiler makeup water applications
• Intermediate atmospheric vent provides positive protection against back-siphonage and backpressure
• Purge and quick fill feature speeds up system commissioning and maintenance flushing
