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. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug [2] can be screwed in to close or shut the valve. The plug is also called a disc or disk.

WHAT’S THE DIFFERENCE: VALVES – BALL, GATE, AND GLOBE VALVE?

This article is all about valves, and the various types of valves and fittings available. Valves are mechanical or electro-mechanical devices that are used to control the movement of liquids, gases, powders, etc. In most instances, valves rely on some form of mechanical barrier—a plate, a ball, a diaphragm, for example—that can be inserted and removed from the flow stream of the material passing by. Some valves are designed as on-off varieties, while others allow very fine control of the passage of media. Material selection plays an important role in specifying valves to ensure the compatibility of the wetted parts of the valve with the fluid or powder passing through it.

The gate valves are so called because the gate-shaped wedge inside is the most used, as well as the most abused, type of valve. Though designed to isolate or connect fluids, they are sometimes wrongly used for flow control. The gate valve should not be used for controlling the fluid flow or for throttling the flow as it can damage the valve due to the high velocity of fluid when the valve is only slightly open. They are normally used in applications where a minimum restriction to the flow of fluid is a design requirement and only an On-Off type of control is required. Normally the gate valves suffer from one common problem after long service and that is the valve becoming tight due to the deposition of silt on the guide ways.

Difference between Globe Valve and Gate Valve ?

A valve is used to control flow of liquids and gases. And ball, gate and globe valves are used to control flow of liquids. These valves in all forms are used to create waterways, and it is therefore essential to understand the differences and their uses. Ball valve made of solid elements offers high durability, and have the ability to function perfectly even after long idle time. It has a sphere made of brass, stainless steel, or chrome plated brass, embedded inside the conduit.


They offer more resistance to fluid flow, and have a high-pressure drop even when the.

Apr 12, Posted by Bundor. Both gate and butterfly valves are two very common valves. The two have great differences in their own structure and usage methods, and in adapting to working conditions. This article will help users to better understand the difference between gate valve and butterfly valve, so as to better help users to select the valve.

Both flow valves,Globe valve and gate valve have similar external housing but operational functions of both differ little. The main difference between globe and gate valve is in the form of the inner elements and the form of the flow inside the both valves.

Повисла долгая тишина. Сьюзан словно во сне подошла и села с ним. - Сьюзан, - начал он, - я не был с тобой вполне откровенен. ГЛАВА 73 У Дэвида Беккера было такое ощущение, будто его лицо обдали скипидаром и подожгли. Он катался по полу и сквозь мутную пелену в глазах видел девушку, бегущую к вращающейся двери. Она бежала короткими испуганными прыжками, волоча по кафельному полу туристскую сумку. Беккер хотел подняться на ноги, но у него не было на это сил.

По приезде группу сразу же разделили. Все они подверглись проверке на полиграф-машине, иными словами - на детекторе лжи: были тщательно проверены их родственники, изучены особенности почерка, и с каждым провели множество собеседований на всевозможные темы, включая сексуальную ориентацию и соответствующие предпочтения. Когда интервьюер спросил у Сьюзан, не занималась ли она сексом с животными, она с трудом удержалась, чтобы не выбежать из кабинета, но, так или иначе, верх взяли любопытство, перспектива работы на самом острие теории кодирования, возможность попасть во Дворец головоломок и стать членом наиболее секретного клуба в мире - Агентства национальной безопасности. Беккер внимательно слушал ее рассказ. - В самом деле спросили про секс с животными. Сьюзан пожала плечами. - Обычная проверка кандидата.
