A temperature & pressure relief valve is generally located at a place closer to the top of the water heaters present in our homes. These valves have a lever that can be lifted up or down along with a discharge pipe that is running from the valve straight down to the water heater’s bottom. The primary use of the temperature-pressure relief valve is for releasing water and ultimately lowering the tank’s internal pressure, in cases when the pressure or temperature gets very high inside the water heater. In the absence of a temperature-pressure relief valve, the water heater would be running the risk of exploding if the pressure or temperature gets higher than the tank was originally intended to handle.
In commercial and residential water heater along with hot water storage tank applications, Temperature & pressure relief valves are used for offering automatic pressure and temperature protection for hot water heaters and hot water supply tanks. We have a full line of products in different sizes, pressure ratings, and inlet/outlet types.
These Plumbing Brass valves can be used to protect the equipment from any type of catastrophic failure and excess pressure. They are known as the last line of defense. In residential water heaters, these valves are used and are designed traditionally for relieving pressure at 150 psi and temperature at around 210 degrees F. These relief valves are ANSI, ASME and CSA (AGA) approved for protecting the water heater from getting damaged due to excessive temperatures and pressure by the discharged water.
Expansion of water happens when it is heated. Water when heated to its thermostat setting in a 40-gallon water heater will end up expanding by around ½ gallon. The extra amount of volume that is created by this expansion needs a place to go or it will increase dramatically like the water is heated in a closed system. When the Temperature & Pressure Relief Valves release around one cup of water for every 10 gallons of heater capacity at each heating cycle, then it is a good example of thermal expansion. When it comes to suppliers for a wide range of engineering and industrial solutions in the Middle East and GCC region, then Dutco Tennant LLC is a well-recognized name. For the last four decades, we have been working with various private and public sector companies and have contributed to the infrastructural development of various cities.
The Temperature and Pressure Relief Valves are a special range of plumbing safety valves that are responsible for ensuring that the hot temperature-pressure relief water tank can stay within the designed pressure and temperature limit. They are placed over or near the side of the top of the water heaters. The valves are having a lever that can be lifted down or up along with a discharge pipe that runs from the valve straight via the bottom of the water heater. These heaters can start to shake up and the produced moisture is higher compared to the normal. The pressure inside the water heater gets increased by the steam which causes it to become more unstable. When the heaters get unbalanced or overloaded, they can start shaking like the other clothes washer. Exactly at this point, the Temperature and Pressure Relief Valves play their part. When anything wrong happens, the vale will automatically open for relaxing the excess amount of pressure via the discharge line. If the water heater does not have a TPR valve, the heater can actually blow up and the safety of your family can be compromised. These small-sized devices play an important role in the overall safety of the heater, of the household and the families and they are needed to be inspected, checked, replaced and maintained for replacing or preventing excess pressure and overheat.
