Válvula de bola con brida manual American Standard Q41F, fabricado en acero inoxidable y acero al carbono.
The Q41F manual flange ball valve is mainly used to cut off or connect the medium, y también se puede utilizar para la regulación y control de fluidos.. Compared with other valves, ball valves have the following advantages: 1. Low fluid resistance: Ball valves have the lowest fluid resistance of all valve types; even reduced-bore ball valves have very low fluid resistance. 2. Quick and convenient opening and closing: A 90° rotation of the valve stem completes the fully open or fully closed action, easily achieving rapid opening and closing. 3. Good sealing performance: The ball valve seat seal ring is generally made of elastic materials such as PTFE, which easily ensures a seal, and the sealing force of the ball valve increases with the increase of the medium pressure.

Válvula de bola con brida manual American Standard Q41F, fabricado en acero inoxidable y acero al carbono. Application Features
The Q41F manual flange ball valve is mainly used for cutting off or connecting media, y también se puede utilizar para la regulación y control de fluidos.. Comparado con otros tipos de válvulas, ball valves have the following advantages:
1. Low fluid resistance: Ball valves have the lowest fluid resistance of all valve types; even reduced-bore ball valves have relatively low fluid resistance.
2. Quick and convenient opening and closing: A 90° rotation of the valve stem completes the fully open or fully closed action, easily achieving rapid opening and closing.
3. Good sealing performance: The ball valve seat seal ring is generally made of elastic materials such as PTFE, which easily ensures a seal. Furthermore, the sealing force of the ball valve increases with the increase of media pressure.
4. Reliable stem seal: During the opening and closing of the ball valve, the valve stem only rotates, therefore the stem packing seal is not easily damaged, and the sealing force of the stem back seal increases with the increase of media pressure.
5. Ball valves only require a 90° rotation to open and close, making them easy to automate and control remotely. Ball valves can be equipped with pneumatic, eléctrico, hydraulic, pneumatic-hydraulic, or electro-hydraulic actuators.
6. Ball valve passages are smooth and flat, preventing media accumulation and allowing for pipeline ball passage.
