The difference between a globe valve and a ball valve

 In this article, we are going to examine the differences between globe valve and ball valve. We will first introduce each one separately. Then we examine their differences. If you want to know these differences, read this article to the end.

Globe Valve

A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. High-head-loss valves, such as globe valves, are commonly used for control purposes. Significant losses occur with these types of valves, however, even when they are fully open. If the evaluation shows that a control valve is needed, choose the type that minimizes pressure drop across the valve. Read more



Ball Valve

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status. The shut position 1/4 turn could be in either CW or CCW direction. 
all valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack their fine control in throttling applications.

Globe Valve vs Ball valve

the main difference of globe valve vs ball valve is the way they open and close the flow. A globe valve is used to control and throttle the flow while with a ball valve you can’t control the flow and the only thing you can do with the flow is to close it. With a globe valve you are able to regulate the flow whereas the ball valves are well-performed for the closing the flow without any pressure drops.
If you need to keep the flow closed for a long period of time, use a ball valve. A ball valve works more efficiently in high-pressure systems like fire hoses.

Introduction of electric motors and types

Image
  You've probably heard of electric motors by now. A critical piece in all electrical appliances. In this article, we will introduce electric motors in detail and examine its types, so stay tuned. An electric motor is a component that converts electrical energy into kinetic energy. Most electric motors are  electromagnetic -based. Most electric motors are rotary, but there are also linear motors. In a rotating motor, the moving part (usually inside the engine) is called the impeller or rotor, and the fixed position is called the station or stator. The motor consists of electric magnets wound on a frame. Although this frame is often referred to as armature, the term is often misused. Types of Electric Motor Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-...

Introduction and review of Suspension Insulators and Strain Insulators

Image
  In this article, we will have a detailed explanation and review of Suspension Insulators and Strain Insulators. Join us and read this article. First, we will introduce Suspension Insulators, and after reviewing it, we will submit Strain Insulators What is Suspension Insulators  ? The suspension type insulator consists of several insulation parts connected in series and forms a string. In suspension insulators, each porcelain discs is designed to work at 11 kV, and as the operating voltage increases, the number of discs in the string and in series increases as well. For example, the number of insulator discs required is 12 in 132 KV transmission lines.  Read More in Linquip What is Strain Insulators  ? According to  Wikipedia , A strain insulator is an electrical insulator designed to work in mechanical voltage (strain) to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring to support radio...

Everything you should know about HVAC

Image
What is HVAC? What do you know about it? What is its use? In this article, we will take a closer look at HVAC, so join us to get the answers to these questions and any other questions about HVAC. The importance of HVAC Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of  mechanical engineering , based on the principles of thermodynamics, fluid mechanics and heat transfer. As was mentioned earlier, an  HVAC system  is intended for thermal control of areas as well as comfort for occupants. Temperature is factor that affects the performance and health status of many systems. Take the case of a server room temperature as an example for which high temperature adversely affects the system’s reliability and operation of the servers is a great source of heat ge...
