How much pressure can the butterfly valve bear?

As we all know，how much pressure the butterfly valve can withstand is mainly related to the butterfly valve sealing material.

At the earliest, the butterfly valve was an ordinary flap valve. Its function is very simple. It can only be used to control the size of the water flow and the pressure it can withstand is small. With the advancement of science and technology, the production process of butterfly valves has become more mature, and the types of butterfly valves are also increasing. This also allows the butterfly valve to be used in different types of operating conditions. So how much pressure can the butterfly valve bear?

According to different sealing materials, butterfly valves can be divided into soft sealing butterfly valves and hard sealing butterfly valves. How much pressure the butterfly valve can withstand is mainly related to the butterfly valve sealing material.

The sealing material of the soft sealing butterfly valve is mainly ethylene propylene diene rubber, nitrile rubber, polytetrafluoroethylene and the like. Because of the limitations of sealing materials, soft seal butterfly valves can withstand pressures of up to 16 kg. If the pressure is too high, the medium in the pipe will break through the seal pair, causing the valve to leak and be damaged.

The sealing material of the hard sealing butterfly valve is cemented carbide, so the hard sealing butterfly valve is usually used on the pipeline of medium and high pressure medium. The hard-sealed butterfly valve of the Bundor valve has a pressure range of 63 kg.

In addition, the soft sealing butterfly valve can only be used under low temperature or normal temperature conditions. Generally, the temperature should not exceed 100 ° C when using EPDM rubber. The temperature should not exceed 80 ° C when using nitrile. The temperature should not exceed 150 ° C when using Teflon. The highest temperature resistance of the hard-sealed butterfly valve of the Bundor Valve is 425 °C.
