PRODUCT OVERVIEW
Electric cast steel fixed ball valve is generally used for various pipelines with high pressure and large diameter. It adopts the design of upper and lower valve stems, fixed valve cores (shaft supported) and movable sealing seats. When closed, the ball will not displace under the action of medium pressure and work more stably. The upper and lower shafts usually connected with the ball are equipped with rolling bearings or sliding bearings to reduce the friction generated by the journal during opening and closing and reduce the operating torque. They are widely used in various industries. According to different materials, it can be applied to water, steam, oil, liquefied gas, natural gas, gas, nitric acid, acetic acid, oxidizing medium, urea and other media.
