Watts Water Heater Expansion Valve

We offer a range of expansion tanks for potable and non potable applications.

Watts water heater expansion valve.

Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering. Inital temperature start note. 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. Relief valve the set pressure of the t p valve or the secondary relief valve setting.

Asme ansi and csa aga approved relief valves protect the water heater from excess pressures and temperatures by discharging water. Complies with lead free installation requirements.

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. Water heater accessories expansion tanks expansion tanks. Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering. 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.

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. The last line of defense for pressurized equipment temperature and pressure t p relief valves protect equipment from excess pressure and ultimately catastrophic failure. When water is heated it expands due to a phenomenon known as thermal expansion.

Here is a water heater with a watts 210 valve. 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. 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. When water is heated it expands due to a phenomenon known as thermal expansion. We offer a range of expansion tanks for potable and non potable applications. 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.

Lower start temperatures should only be used if the entire contents of the water heater are drained on each use.
