Q641FAir Actuated Ball ValveProduct Overview:

Q641FFramed pneumatic ball valveIt's a corner turning90°Rotary valves with excellent sealing performance, high flow coefficient, low pressure drop coefficient, simple structure, long service life, and easy maintenance. Widely used in system control for industries such as chemicals, petrochemicals, light industry and textiles, power, food, refrigeration, and papermaking.


Q641F气动Ball Valve with FlangeProduct Description:


Primarily used for cutting off or connecting mediums in pipelines, also suitable for fluid adjustment and control. Compared to other valve types, it offers several advantages:


1Low fluid resistanceQ41Floating ball valves are one of the valve types with the least fluid resistance, even those with reduced diameters have relatively low fluid resistance.

2Thrust bearings reduce the friction torque of the valve rod, enabling long-term balanced and flexible operation of the valve rod.

3The valve seat has excellent sealing performance, utilizing seals made of materials like PTFE, which are easy to seal. Moreover, the ball valve's sealing capability increases with the increase in medium pressure.

4The valve stem seal is reliable. Since the valve stem only rotates and does not move up and down, the stuffing box seal of the valve stem is less prone to damage, and its sealing capability increases with the increase of the medium's pressure.

5Due to the excellent self-lubricating properties of materials like PTFE, the friction loss with spheres is minimal, resulting in a longer service life.

6Bottom-mounted valve stems and stem head steps prevent stem ejection. In the event of a fire causing damage to the stem seal, metal contact can still form between the step and the valve body, ensuring stem sealing.
