Amtrol 109-1 Fill Trol Tank W/ Valve 1/2" NPTF 109-1 510-632-088

The Amtrol 109-1 Expansion Tank with Valve is an essential component of the HVAC system that is used to control pressure fluctuations in closed-loop hydronic heating systems. With a 1/2” NPTF connection this pre-pressurized tank has an automatic Fill-Trol valve that keeps system pressure so that over-pressurization is avoided and pressure on system parts is minimized. It is perfect for use in combination with boilers, radiators and other hot water HVAC heating appliances. By accommodating thermal expansion, it increases the efficiency and life of the system. This maintains performance guards against water hammer and provides safe operation for residential and light commercial HVAC system applications.
