    What are the types of Valves

    Written By: Kashif Zaman Usafzaie‎‏ Valves Uses: Valves are used for: 1. Full flow of full throttle: Which is the wide range of valves use, because valves are designed in a way that reduce pressure losses for fluids passing through these valves, diaphragm valve is used with dangerous and toxic liquids. 2. Flow regulating: Sometimes, we need to regulate flow by changing the valve position between fully open and fully closed and throttling the valve reducing the flow, this is accomplished by using control valves. 3. One-way flow: Sometimes, we need to prevent liquids in the reverse way, this type of valves is installed at pump or compressor discharge lines to…

    Valve Types

          GENERAL In industrial piping, the control of flow is very important. Mechanical devices used for flow control are called valves. The principal functions of valves are: · Starting and Stopping Flow · Regulating or Throttling Flow · Preventing Back Flow · Regulating Pressure · Relieving Pressure Steel valves are classified by nominal pipe size (NPS) and by pressure-temperature service ratings. There are two service ratings; a Primary Rating and a Cold Working Pressure Rating: · The Primary Rating is a pressure rating established by standards and accepted practice at an elevated temperature. · The Cold Working Pressure Rating is the rating at ambient temperature (minus 20°F to 100°F). This rating is…

    Control Valves

     صمامات السيطرة Control Valves المهندس أكرم صادق عبد المهدي – ماجستير تكنلوجيا التعليم الهندسي / الهندسة الكهربائية   مقدمة : ان الحقول الصناعيه والمعامل تتضمن على عشرات او مئات من حلقات السيطرة (Control Loops) وان هذه الحلقات مصممه لتحافظ على جعل متغيرات السيطرة (Process Variables) ضمن مديات العمل المحددة او المرغوبه وبما يضمن الوصول الى تحقيق السيطرة المثلى على نوع المنتوج (Product Quality) وكميته (Product Quantity) . كل من هذه الحلقات تتحسس وتولد بذاتها اضطرابات (Disturbance) اضافه انها تتفاعل فيما بينها لتولد اضطرابات تؤثر في متغير السيطرة  . ان هذه الاضرابات يتم تحسسها عن طريق المتحسسات (Sensors) ثم تكبر وترسل عن طريق المرسلات (Transmitters) الى اجهزة المسيطرات التي بدورها تقوم…
