WHAT IS GATE VALVE

 

WHAT IS VALVE ?

Valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids and slurries) by opening, closing or partially obstructing the passage ways.

 




PURPOSE OF VALVES IN INDUSTRIES 

Valves serve a variety of purposes in the industrial, engineering, manufacturing and scientific communities. Selecting the right valve can determine the success or failure of the system or process. The main purpose of a valve is to control media flow through a system.

 



CLASSIFICATION OF VALVES

Based on Functions

Based on Obturator Movement

Based on Operators

Based on End Connection

  

Purpose of using Gate Valve on stream

 

Gate Valve is used to open and close the flow only. Not commonly used in flow control with the following components.

Gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve.A gate valve is the most common type of valve used in any process plant. It is a linear motion valve used to start or stop fluid flow. In service, these valves are either in a fully open or fully closed position. When the gate valve is fully open, the disk of a gate valve is completely removed from the flow.

Magnetic Particle Testing (MPT)

Image
 Magnetic Particle Testing    Magnetic Particle Testing (MPT), also known as Magnetic Particle Inspection, i.e. a nondestructive examination (NDE) technique used to detect surface and  subsurface diecounitinuties  in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys. Because it does not necessitate the degree of surface preparation required by other nondestructive test methods, conducting magnetic particle test Is part of ASME SECTION V ARTICLE 7 requires the magnetic particle visible method (color contrast) be evaluated with a minimum light intensity of 100 footcandles on the part surface Advantages of the Magnetic Particle method of Non-Destructive Examination are: It is quick and relatively uncomplicated. It gives immediate indications of defects. It shows surface and near surface defects, and these are the most serious ones as they concentrate stresses. Magnetic Particle Testing (MT), also referred to as Magnetic Particl...
