Can butterfly Valves be used for hot water?
Posted by Bundor valve
Whether the butterfly Valve can be used in the hot water pipeline, the key lies in the material of the Valve seat sealing surface that directly contacts the hot water in the butterfly Valve body.
Can butterfly Valves be used for hot water? Bundor Valve has introduced to you in the previous article, butterfly Valve is suitable for fresh water, sewage, sea water, salt water, which requires complete sealing, zero gas test leakage, high life expectancy, and working temperature between -10 degrees and 150 degrees. Steam, natural gas, food, medicine, oil, various acid and alkali and other pipelines.
Whether the butterfly Valve can be used in the hot water pipeline, the key lies in the material of the Valve seat sealing surface that directly contacts the hot water in the butterfly Valve body. The hot water we usually say is generally water above 70°C. Under this temperature, there is no problem at all if a hard-sealed butterfly Valve is used.
But if it is a soft-sealed butterfly Valve and a rubber-sealed Valve seat, can it be used for hot water?
If you search for the answer on the Internet, you should see that many people do not recommend using soft-sealed butterfly Valves for hot water, because the rubber seat of the soft-sealed butterfly Valve will accelerate the aging and shorten the service life of the Valve if it is exposed to hot water for a long time. , Affect the sealing performance of the Valve.
This statement is not a problem. The theoretical temperature resistance range of rubber materials is -20~150℃, but because the quality of rubber produced by various manufacturers is not uniform, this temperature resistance range will shrink greatly in actual use. In the environment, of course it will accelerate the aging.
However, the soft-sealed butterfly Valve is not completely unusable for hot water pipes. It can be made of high-temperature resistant rubber material. The effect will be much better and the service life will be longer, but the cost is also higher.
You can use hard-sealed butterfly Valves, ball Valves, gate Valves, globe Valves and other Valves instead.
