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, chimico, metallurgical, industria leggera, fabbricazione della carta, power plants, refrigeration, and other industrial fields.
Q941F-16P US API Stainless Steel Electric Ball Valve Product Features
(1) Bassa resistenza ai fluidi: Le valvole a sfera hanno la resistenza ai fluidi più bassa tra tutti i tipi di valvole. Even reduced-bore ball valves have very low fluid resistance.
(2) Thrust bearings reduce stem friction torque, 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) Reliable stem sealing: Since the stem only rotates and does not move up or down, the stem packing seal is not easily damaged, and the sealing capacity increases with the increase of medium pressure.
(5) Due to the good self-lubricating properties of materials such as PTFE, the friction loss with the ball is small, resulting in a long service life for the ball valve.
(6) The bottom-mounted stem and the raised step on the stem head prevent the stem from being ejected. If a fire causes damage to the stem seal, the raised step can still form metal-to-metal contact with the valve body, ensuring the stem seal.
