I. Introduction of QF41Fs discharge ball valve


它具有相同的旋转90度的动作,不同的是旋塞体是球体,有圆形通孔或通道通过其轴线。 The discharge ball valve has the same action of rotating 90 degrees, the difference is that the cock body is a sphere and has a circular through hole or channel through its axis. The discharge ball valve is mainly used to cut, distribute and change the flow direction of the medium in the pipeline. It only needs to be rotated by 90 degrees and can be closed tightly with a small torque. V型球阀 The discharge ball valve is most suitable for use as an on / off valve. However, recent developments have designed the discharge ball valve so that it can be used for throttling and controlling flow, such as V-type ball valves .

Second, the main features of QF41Fs discharge ball valve

The main features of the discharge ball valve are its compact structure, reliable seal, simple structure, and easy maintenance. The sealing surface and the spherical surface are often closed. General working medium, but also suitable for harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., are widely used in various industries. The ball valve body can be integrated or combined.

Design and manufacturing: GB12237
Structure length: GB12221
Flange connection size: JB78

Use of QF41Fs discharge ball valve

This valve is used to control highly corrosive media. The surface of the valve body is covered with a variety of fluoroplastics, which are suitable for different working temperatures and fluid pipelines. It has the characteristics of high strength and good corrosion resistance.
Applicable temperature: ≤100 ℃, ≤120 ℃, ≤150 ℃, (according to the lining material)
Pressure level: 0.6, 1.0, 1.6
