Watts Water Heater Expansion Valve

Our potable water expansion tanks are designed to absorb the increased volume of water created by thermal expansion and maintain a balanced pressure throughout the potable water supply system.

Watts water heater expansion valve.

Asme ansi and csa aga approved relief valves protect the water heater from excess pressures and temperatures by discharging water. Lated from the public water supply by a one way valve such as a pressure reducing valve backflow preventer or check valve. This type of valve is used instead of a temperature pressure relief valve tpr and it shuts off the gas if the water heater over pressurizes or if the water heater gets too hot. Series lf210 5 lead free automatic gas shutoff valves are used in gas water heater applications to protect against overheating water in the domestic hot water supply heating system.

We offer a range of expansion tanks for potable and non potable applications. It is an immersion type valve that automatically shuts off the gas supply to the heater if the temperature reaches 210 deg f 99 deg c. Set the cold water start temperature to 90 f. Try our project specification tool.

Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering. The last line of defense for pressurized equipment temperature and pressure t p relief valves protect equipment from excess pressure and ultimately catastrophic failure. Water heater accessories expansion tanks expansion tanks. T p valves used on residential water heaters are typically designed and manufactured to relieve pressure at 150 psi and temperature at 210 degrees f.

They are used to prevent plumbing system and or water heater damage as well as unnecessary relief valve discharge caused by excessive pressure from thermal expansion. Water heater installation maintenance and repair is supported by our line of drain tubes expansion tanks and valves designed specifically for water heater applications. Lower start temperatures should only be used if the entire contents of the water heater are drained on each use. When water is heated it expands due to a phenomenon known as thermal expansion.

When water is heated it expands due to a phenomenon known as thermal expansion. Series lfbrvm1 combination ball valve and relief valve is an easy to install two in one device used to shut off the water supply to the water heater and to provide protection against excess water pressure caused by thermal expansion. Inital temperature start note.
