the typical features of the sphere is a fan, it means using the ball part of the generation of a whole sphere. Fan sphere including fully closed sphere of logistics area and provide enough sealing surface of the sphere. Industrial Industrial Valves normal fan sphere is trunnion installation type ( Figure 4. 32) 。 For trunnion installations, the ball is made up of shaft and the other - as opposed to a shaft side A shaft or pillar support, it can be separated from a sphere or as a whole. Because of the support is not sealed bear, trunnion ball normal installation design is with a seal ( But two sealing structure is feasible) It produces smaller friction between the ball and seal. Using the trunnion installation structure on a demanding high around working condition of high pressure is the best.

ball valves can be equipped with qin seal or metal seal. For soft seal, industrial valves equipped with a metal or hard on elastomer seal elastomer spare ring so that the sealing surface pressure, under the condition of the elastomer failure, its action as - Spare parts and additional cleaning to the sealing surfaces. Of strong corrosion or explosion-proof condition, such as the working condition of oxygen, is prohibited to use in the elastic metal spare ring. If the need for strict temperature using metal seal. Industrial Industrial Valves manufacturer should pay attention to the song to adapt to each other metals to prevent wear and scratches on the surface of the metal. Metal sealing to heat treatment and/or sphere and capping.
