What’s the main use of a ball valve?

Quick shutoff and flow control.

Is a ball valve full port or reduced port?

It can be either, depending on the design.

Can ball valves be used for gas?

Yes, if the material and rating are appropriate.

Do ball valves leak easily?

No, they offer tight sealing when properly maintained.

Are ball valves easy to automate?

Yes, they support pneumatic and electric actuators.

صمام الكرة هو نوع من صمامات ربع دورة يتحكم في التدفق باستخدام كرة مجوفة مثقبة ومحورية داخل جسم الصمام. عندما يكون ثقب الكرة محاذيًا لخط الأنابيب، يتدفق السائل بحرية؛ وعند تدويره 90 درجة، يُمنع التدفق تمامًا. هذه الآلية البسيطة تجعل صمامات الكرة موثوقة للغاية لتطبيقات الإغلاق والتحكم. تشتهر صمامات الكرة بأدائها المحكم في الغلق، ومتانتها، وسهولة تشغيلها. يمكنها التعامل مع ظروف الضغط ودرجة الحرارة العالية، وهي مناسبة للغازات والسوائل، وحتى الوسائط المسببة للتآكل، حسب المواد المستخدمة. بفضل انخفاض الضغط البسيط والتحكم السريع في التشغيل والإيقاف، تُستخدم صمامات الكرة على نطاق واسع في صناعات مثل النفط والغاز، ومعالجة المياه، والمعالجة الكيميائية، والسباكة العامة. تتوفر بأنواع مختلفة مثل ثنائية الاتجاه، وثلاثية الاتجاه، وعائمة، ومثبتة على محور، ويمكن تشغيلها يدويًا أو هوائيًا أو كهربائيًا.
