Watts water heater expansion valve.

Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering. When water is heated it expands due to a phenomenon known as thermal expansion. Set the cold water start temperature to 90 f. Here is a water heater with a watts 210 valve.

Lated from the public water supply by a one way valve such as a pressure reducing valve backflow preventer or check valve. The watts 210 valve is no longer approved for use in the city of los angeles. 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. Complies with lead free installation requirements.

Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering. 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. The last line of defense for pressurized equipment temperature and pressure t p relief valves protect equipment from excess pressure and ultimately catastrophic failure. Relief valve the set pressure of the t p valve or the secondary relief valve setting.

Water heater accessories expansion tanks expansion tanks. 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. Water heater installation maintenance and repair is supported by our line of drain tubes expansion tanks and valves designed specifically for water heater applications. 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.

Water heater accessories expansion tanks expansion tanks. We offer a range of expansion tanks for potable and non potable applications. Asme ansi and csa aga approved relief valves protect the water heater from excess pressures and temperatures by discharging water. 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.

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. Lower start temperatures should only be used if the entire contents of the water heater are drained on each use. Watts potable water expansion tanks are de signed to absorb the increased volume of water created by ther mal expansion and to main tain a balanced pressure throughout the potable water supply system. When water is heated it expands due to a phenomenon known as thermal expansion.
