SHUANGLIN
The SHUANGLIN VALVE Automatic Filling Valve is designed to automatically maintain the proper water pressure in closed-loop heating and HVAC systems. When the system pressure drops below the preset level, the valve opens automatically to replenish water and closes once the required pressure is restored. This helps reduce manual operation, improve system efficiency, and protect boilers, pumps, and other heating equipment from pressure fluctuations.
Manufactured from high-quality brass with precision machining, the valve offers excellent corrosion resistance, stable pressure regulation, and a long service life. It is suitable for residential heating systems, underfloor heating, wall-hung boilers, heat pumps, and commercial HVAC installations.
