Global valves are similar to the gate valves and a use linear motion for the throttle flow.They are actually used to control the flow in a pipeline also they are used to regulate the position of a movable plug with relation to the ring seat which is stationary.
2. Introduction
• Globe Valves are one of the popular type of valves
that are used in varied applications.
• These valves are similar to the gate valves and a use
linear motion for the throttle flow.
• They are actually used to control the flow in a
pipeline also they are used to regulate the position
of a movable plug with relation to the ring seat
which is stationary.
3. Pros
• The Globe valves throttling & full-closing
characteristic is good.
• Shorter opening and closing time & a positive shut-
off method.
• Easier body ring seating surface process.
• Can be used as stop-check valves.
Con’s
• Loss of pressure is high.
• They require a large amount of force to close under
high pressure.
4. INDUSTRIAL APPLICATIONS - OIL & GAS
• Oil & Gas wells with their production facilities are heavy users of globe valves among
other type of valves.
• Even though oil gushers discharging into air hundreds of feet are not likely to occur any
more, still there are some of the potential pressure of underground oil & gas this is why
the well heads are placed around the top of a well’s long string side of the pipe.
• These are the type of assemblies, with their combination of globe valves with their
special fittings, which are designed to handle 10,000 psi or more pressures.
5. INDUSTRIAL APPLICATIONS - OIL & GAS
• Rarely is it found on the wells dug on the land these days, since the maximum higher
pressures are often found in the deep wells that are present offshore.
• The Process equipment to pre-treat the oil or gas needs a specific number of globe
valves that are basically rated for their tensile strength.
• Since a high corrosive fluid like hydrogen sulphide is present in the raw petroleum
stream causing the formation of an element which also known as sour gas, can be a
lethal one. Hence in order to fend of the sour gas, special materials processing
techniques and manufacturing techniques must be followed.
6. INDUSTRIAL APPLICATIONS - CHEMICAL
• The chemical industry is one of the biggest users of valves of all types & materials.
• From small plants to big petrochemical structures that are usually located on the Gulf
Coast, these valves are a huge part of piping systems of the chemical process.
• Most of the applications in chemical processes are of low pressure compared to many
power generation and refining processes.
7. INDUSTRIAL APPLICATIONS - CHEMICAL
• The strong seated globe valve, which is zero-leakage shutoff since it is a perfect fit for
many chemical plant applications.
• Hence in these scenarios it is better to use the valves which are designed with the
thinner walls and the lighter weights, that are basically the gate or globe valves of
choice.
• Controlling of some chemical elements are also better accomplished with the globe
valves. For some of the tougher and highly corrosive applications, more protective
globe valves is much needed.
