This year’s Dervos annual conference was noticeably more grand and well-organized than in previous years.   In the morning session, each department delivered its annual work summary, reviewing key projects and achievements over the past year. Teams also openly shared the challenges encountered during implementation and the practical experience gained along the way.   Through this cross-department exchange, everyone developed a clearer understanding of one another’s responsibilities and workflows, laying a stronger foundation for future collaboration and communication.     In the afternoon session, the Outstanding Employee awards were presented. Each nominee shared their work achievements and practical experience, demonstrating a strong sense of responsibility and execution across different roles. It is precisely this proactive mindset, collaborative spirit, and down-to-earth working approach of Dervos employees that drives the team steadily toward its shared goals.     Showing up on time every single day throughout the year — that’s quite an achievement. Ian has now received the Perfect Attendance Award for two consecutive years.     During the annual conference, Dervos also presented medals and exclusive commemorative gifts to employees who have completed five years of service.     Dervos values the long-term dedication and consistent commitment of its team members, and sincerely appreciates the trust and contributions they have made over the years. For many at Dervos, the company is not only a platform for professional growth, but also a stage where shared goals and collective efforts come to life. In the evening, the annual conference transitioned into the banquet segment. Performances and interactive games were seamlessly interspersed, creating a relaxed yet organized atmosphere.     Laughter and cheers echoed throughout the venue, and in the moment the camera shutter clicked, the excitement and joy were captured in a single frame.     Eric said: "Let’s dream together, DERVOS's dream. A dream where we all play a part, piece by piece, it becomes a reality." For Dervos, the annual meeting is not just about "summarizing the year," but about bringing our hearts together, strengthening our resolve in doing the same thing, and then continuing to move forward, step by step, with steady progress.            

Ball valves and plug valves differ significantly in several aspects, including structure, operating principle, mode of operation, flow control capability, sealing performance, and application scenarios. These differences enable the two types of valves to perform distinct roles in their respective fields.   Structural Differences   The ball valve, a design evolved from the plug valve, utilizes a spherical element as its core component. By rotating the ball 90° around the stem axis, the valve can be opened or closed. Its structure is straightforward, consisting primarily of a spherical closure element with a through-bore housed within the valve body.   In contrast, the structure of a plug valve is more complex. It comprises multiple components such as the valve body, bonnet, plug, seat, and stem. The closure element is a cylindrical or tapered plug that controls flow by rotating 90°, aligning or misaligning the port in the plug with the flow passage in the valve body to achieve opening or shutoff.   Operating Principle   The operating principle of a ball valve relies on the rotation of the ball to control the on-off flow of fluid. When the ball is in tight contact with the valve seat, the clearance between them is completely sealed, thereby preventing fluid leakage. When the ball rotates to a position disengaged from the seat, the fluid is allowed to flow freely through the passage inside the valve body.   The operating principle of a plug valve differs in that it primarily controls the flow passage by rotating the plug element to open or close the valve. In a plug valve, the plug is connected to the stem and rotates together with it to achieve flow control. The closure element is a tapered plug with a port, and the flow passage is designed to be perpendicular to the axis of the plug. This configuration enables the plug valve to operate more efficiently and reliably during opening and closing.   The operation of a ball valve is notably simple, requiring only a 90-degree rotation to achieve opening or closing. This design allows the flow passage to be opened or shut off quickly and smoothly when the ball is rotated by 90 degrees, providing both convenience and efficiency. In addition, ball valves offer relatively low flow resistance in the fully open or fully closed position, making them particularly suitable for applications that require rapid on-off operation.   By contrast, the operation of a plug valve is comparatively more complex, as several turns are typically required to complete the opening or closing action. The valve plug is designed in a cylindrical or tapered form and regulates fluid flow through rotation. Nevertheless, plug valves demonstrate excellent performance in flow regulation, enabling precise adjustment of the flow passage diameter and accurate control of flow rate. However, due to the relatively complicated operating process, plug valves are not well suited for frequent operation...

في أنظمة الصمامات الصناعية، الجودة العالية صمام ذو لوحة مغلقة يضمن التشغيل الآمن والفعال للمعدات. وهو مناسب لخطوط أنابيب الغاز في صناعات المعادن والمعالجة الكيميائية والبترول والشبكات البلدية، حيث يعمل كجهاز فعال لعزل الغاز بشكل إيجابي. مبدأ العمل والميزات يتكون صمام اللوحة العمياء من أجسام صمام يسارية ووسطى ويمينية، ولوحة صمام، وأعمدة، ومعوض، ووحدتي قيادة (للتثبيت والحركة على التوالي). تستخدم آلية التثبيت مجموعة محرك لتشغيل نظام وصلات، مما يسمح لثلاثة براغي لولبية بالعمل بشكل متزامن والضغط على أجسام الصمامات مقابل صفيحة الصمام لتحقيق الإحكام. يوفر هذا التصميم تزامنًا جيدًا وتوزيعًا متساويًا لقوة الإحكام. يتم تركيب بكرات تحديد المواقع على طول الحافة السفلية الخارجية للوحة الصمام لتعزيز موثوقية الإحكام وضمان الاستقرار العام ودقة الإحكام أثناء التشغيل، مما يطيل عمر الخدمة. صمام . تسلسل تشغيل الصمام تقوم وحدة محرك التثبيت بتشغيل آلية المرفق والوصلات، مما يؤدي إلى دوران براغي التوجيه بشكل متزامن وسحب الجسم المركزي بعيدًا عن أسطح منع التسرب (حالة التحرير). تتحرك عجلات التوجيه المثبتة على الجسم المركزي جانبيًا وتدفع في الوقت نفسه صفيحة الصمام. عند فتح جسمي الصمام بالكامل، توضع صفيحة الصمام بين أسطح منع التسرب للجسمين الأيمن والأيسر، وتنفصل أسطح منع التسرب تمامًا. ثم يتم تفعيل وحدة تشغيل الصفيحة. ومن خلال آلية ذراع الرافعة، تدور صفيحة الصمام، مما يؤدي إلى وضع الصفيحة العمياء في موضع خط الأنابيب. ويتم تشغيل وحدة تشغيل التثبيت مرة أخرى لتثبيت صفيحة الصمام بالكامل، وإتمام إغلاق الصمام. فتح الصمام تقوم وحدة التثبيت أولاً بتحرير جسم الصمام بالكامل. ثم تقوم وحدة الدوران بتدوير صفيحة الصمام بحيث تتماشى فتحة المرور مع خط الأنابيب. وأخيراً، يقوم المشغل الكهربائي للتثبيت بالضغط على صفيحة الصمام لإتمام عملية الفتح.
