Válvula de esfera flangeada manual padrão americano Q41F, feito de aço inoxidável e aço carbono.
The Q41F manual flange ball valve is mainly used to cut off or connect the medium, and can also be used for fluid regulation and control. Compared with other valves, ball valves have the following advantages: 1. Baixa resistência a fluidos: Ball valves have the lowest fluid resistance of all valve types; even reduced-bore ball valves have very low fluid resistance. 2. Abertura e fechamento rápidos e convenientes: 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 esfera flangeada manual padrão americano Q41F, feito de aço inoxidável e aço carbono. Application Features
The Q41F manual flange ball valve is mainly used for cutting off or connecting media, and can also be used for fluid regulation and control. Compared with other valve types, ball valves have the following advantages:
1. Baixa resistência a fluidos: Ball valves have the lowest fluid resistance of all valve types; even reduced-bore ball valves have relatively low fluid resistance.
2. Abertura e fechamento rápidos e convenientes: 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. Além disso, 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, a haste da válvula apenas gira, 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. As válvulas de esfera podem ser equipadas com válvulas pneumáticas, elétrico, hidráulico, pneumatic-hydraulic, ou atuadores eletro-hidráulicos.
6. Ball valve passages are smooth and flat, preventing media accumulation and allowing for pipeline ball passage.
