ZHENGFENG VALVES Cast steel ball valve is divided into: floating ball valve and trunnion mounted ball valve. Nylon are usually used as seat sealing ring materials in the production of our company. Therefore, in the selection of the structure and performance of the ball valve, the fire resistance and fire prevention of the ball valve should be considered, especially in the departments of petroleum.
The ball valve with metal seat can be selected for the pipeline system with working temperature above 200 ℃. Metal seat ball valve seal ring is alloy steel overlay welding, so hard seal ball valve will not produce too much wear when opening and closing, generally suitable for high temperature and high pressure conditions.
