שסתום כדורי אוגן ידני Q41F תקן אמריקאי, עשוי מפלדת אל חלד ופלדת פחמן.
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. 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.

שסתום כדורי אוגן ידני Q41F תקן אמריקאי, עשוי מפלדת אל חלד ופלדת פחמן. 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. 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. יֶתֶר עַל כֵּן, 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, חַשׁמַלִי, hydraulic, פנאומטי-הידראולי, or electro-hydraulic actuators.
6. Ball valve passages are smooth and flat, preventing media accumulation and allowing for pipeline ball passage.
