SELECTION METHOD OF GLOBE VALVES

Image
  Introduction: The globe valve, as the name suggests is a linear motion valve with a round globular shaped body which is commonly known as a form of mechanism that is used mainly to impede or regulate the flow of gas or liquid within a pipe. It has a seat that is well structured right in the middle and in turn parallel towards the pipe which has the opening enclosed by using a disc. The globe valve has a plug that is connected to a stem that functions by means of a screw action in the manual valves. Control Method: The globe valve has a disk that opens completely or closes completely the flow path. This action is done in a perpendicular movement to that of the disk away from the seat. The circular space present between the disk and seat ring gradually changes in order to facilitate the fluid flow through the valve. When the fluid travels through the valve it changes the direction many times while increasing the pressure as well. Generally, these valves are fitted with a stem verti...

TYPES OF GATE VALVES & INDUSTRIAL USES

Image
  Gate valve is primarily used for the fluid pipeline, it functions by uplifting the gate out of the path, it is a linear motion valve,   used to start or stop the flow of fluid, and these valves are either in a fully open or fully closed position. Gate valve is also known as sluice valve.   Valve manufacturers   design most of valves as on-off types. We can classify the gate valves in three ways, 1.Types of Disc 2.Types of Body Bonnet joint 3.Types of Stem movement TYPES OF GATE VALVES PARALLEL GATE VALVES: Parallel Gate valves are designed for isolation and transmission of flow in a piping system it can be used to control the flow of gas can be furnished in high differential pressures, it is mainly used in the oil and gas industries. These valves have slide disc with parallel gates faced like a blockage member, the block age member has either a single disc or two discs with a mechanism to spread in between. In the case of a single disc, the force that is given to t...

Global Valve Vs Gate Valves

Image
Globe valves and Gate valves both belong to the most common valves that are used in industrial plants since  both are designed by the  Valve Manufacturers  in such a way that they keep the systems running as efficiently and safely as possible. They have their unique designs which primarily help facilitate their own applications. Globe Valves : The Globe valves are a member of the linear motion valve family which are designed for many industrial applications, including the oil and gas industry. These valves are similar to the gate valves and a use linear motion for the throttle flow. Its functions include start and stop of media as well as regulate the flow it within the pipe. Owing to their design i.e. made with a spherical body and a disc they provide a tighter seal with maximum leakage stopping. The  Global Valve Supplier  often prefer these valves as they are perfectly suitable for applications where the main concerns are safety and leaks. A superior ad...
