The valve body of the electric forged steel ball valve is a two-piece structure, which is threaded in the middle and sealed with PTFE gasketThe other is a three-piece structure with bolts in the middle. Depending on the material of the selected valve seat and gasket packing, it can be adapted to different operating temperatures and media. The products are mainly used in various high-pressure medium transportation pipelines in chemical, metallurgical, petroleum, pharmaceutical and other industries, and the applicable temperature: -196 450;Drive mode: manual, pneumatic, electric, hydraulic, turbine, etc.;Nominal diameter: 1 2"～12"；Nominal pressure: 150lb 1500lb;Applicable medium: water, gas, oil, natural gas and acid and alkali corrosive media.
The valve body is made of forged steel, which can ensure that it has sufficient strength and stiffness under the maximum rated working pressure, and there are no defects inherent in castings. Valve trims are carefully designed and selected to ensure reliability in a wide range of operating conditions. The sufficient wall thickness of the split valve body and the use of high-strength connecting bolts are conducive to the care and maintenance of the valve, and enough to withstand the stress of the pipeline.
The ball is a fixed ball, and the spherical surface is grinding, polished and hardened by the envelope grinding ball process, and separated from the valve stemThe stem is an elongated shaft with a hardened surfaceThe axial load of the ball is transmitted to the valve body by two large self-lubricating brake bearings, which are resistant to wear and operate flexibly with low torque.
Benefits include:
High strength: Due to the forging process, it has excellent mechanical properties and impact resistance to ensure the reliable performance of the valve under harsh working conditions such as high pressure and high temperature.
Good sealing performance: The ball and the valve seat use a special sealing structure, which can be completely sealed when the valve is closed to ensure that the fluid does not leak.
Fast opening and closing speed: The electric actuator can realize fast opening and closing action, improve work efficiency and control accuracy.
Corrosion resistance: The valve body and other key components are usually made of corrosion-resistant materials, which can adapt to the working environment of various corrosive media.
Adjustable performance: Through the control of the electric actuator, the adjustment function of the valve can be realized to meet the flow requirements under different working conditions.
