Q941F-16P US API Stainless Steel Electric Ball Valve Product Applications:

Q941F-16P/25P/40P/64P stainless steel electric ball valves are typically used in applications requiring strict sealing. In addition to controlling gas, liquid, and steam media, they are also suitable for controlling sewage and media containing fibrous impurities. They are widely used in petroleum, 化学, 冶金的, 轻工业, 造纸, 发电厂, 冷藏, and other industrial fields.

Q941F-16P US API Stainless Steel Electric Ball Valve Product Features

(1) 低流体阻力: 球阀在所有阀门类型中具有最低的流体阻力. 即使是缩径球阀也具有非常低的流体阻力.

(2) 推力轴承减少阀杆摩擦扭矩, allowing for long-term balanced and flexible operation of the stem.

(3) Good seat sealing performance: The sealing rings made of materials such as PTFE are easy to seal, and the sealing capacity of the ball valve increases with the increase of medium pressure.

(4) 可靠的阀杆密封: Since the stem only rotates and does not move up or down, 阀杆填料密封不易损坏, and the sealing capacity increases with the increase of medium pressure.

(5) 由于PTFE等材料具有良好的自润滑性能, the friction loss with the ball is small, resulting in a long service life for the ball valve.

(6) 底部安装的阀杆和阀杆头上的凸起台阶可防止阀杆弹出. 如果火灾导致阀杆密封损坏, 凸起的台阶仍然可以与阀体形成金属对金属的接触, 确保阀杆密封.
