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, kemisk, metallurgisk, lätt industri, papperstillverkning, kraftverk, refrigeration, and other industrial fields.

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

(1) Lågt vätskemotstånd: Kulventiler har det lägsta vätskemotståndet av alla ventiltyper. Även kulventiler med reducerat hål har mycket lågt vätskemotstånd.

(2) Axiallager minskar spindelfriktionsmomentet, 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) Pålitlig stamtätning: Since the stem only rotates and does not move up or down, skaftpackningen skadas inte lätt, and the sealing capacity increases with the increase of medium pressure.

(5) På grund av de goda självsmörjande egenskaperna hos material som PTFE, the friction loss with the ball is small, resulting in a long service life for the ball valve.

(6) Den bottenmonterade skaftet och det upphöjda steget på skafthuvudet förhindrar att stammen skjuts ut. Om en brand orsakar skador på stamtätningen, det upphöjda steget kan fortfarande bilda metall-till-metall-kontakt med ventilkroppen, säkerställa stamtätningen.
