Definition of a Globe Valve:
A globe valve gets its name from the shape of its body. An internal baffle divides the body of a globe valve's two parts. It consists of a stem that swings up and down to control fluid flow and a disc (ball or composition or plug) attached to it. The flow line is either parallel to or inclined in the direction of the seats. By sliding the disc against the flow stream, it ceases the flow of fluid.
Since a globe valve is bi-directional, fluid can flow through it in either direction. It can be utilized automatically or manually.
The most frequent application of a globe valve is to open, close, or throttle flow in systems.

Applications of a Globe Valve:
SVR Global is a trust-worthy Globe Valve Manufacturer in USA that has applications such as-
• Applications for steam.
• Extraction drains and condensing air extraction systems.
• Feedwater, condenser air, chemical feed.
• Fuel oil system.
• Piping in small sizes.
• Plumbing sector.
• Provide flow control.
• Provide leak tightness.
• Pumps and compressors.
• Used as an emergency shutdown valve.
• Used in low-point drains and high-point vents.
• Used in systems that require frequent stroking, vacuum or a wide variety of temperature extremes.
• Used in systems where pressure drop is not an issue.
• Water-cooling systems.
Advantages of a Globe Valve:
• Bubble tight shut-off.
• Can be utilized as a stop-check valve by altering the design.
• Controlled precision.
• Easy to maintain.
• Excellent sealing ability.
• Fast-acting.
• Fast operation due to shorter stroke length.
• No fear of wear of seat and disc; hence good for frequent operation.
• Great and precise throttling ability.
• Has excellent closure ability.
• Repair work is easy to repair as the seat and disc can be accessed from the valve top.
• Seats are easy to machine and resurface
• Suitable for high-pressure systems.
• Used for corrosive or highly viscous fluids.

Disadvantages of a Globe Valve:
• Can be installed only in one direction.
• Complex design.
• Create noise during operation.
• Expensive.
• Heavier.
• High head loss from two or more right-angle turns of flowing fluid. through the valve body.
• High pressure drops due to numerous directional shifts.
• High torque.
• Huge power is required to open.
• Internal trim parts can be damaged by pulsations and shocks.
• Large disc assembly opening.
• Longer operating time.
• Low-flow coefficients.
• Not recommended to use in pipes with big diameter.
• Not suitable for sterile or clean applications.
• Susceptible to Cavitation and flow-induced vibrations.
• The disc is mounted on the stem in a cantilevered position.
• More power is required to seat the valve.
• Throttling flow under the seat and shutoff flow over the seat.
Industries where Globe Valves are operated:
• Marine
• Oil and Gas
• Power generation
• Pulp and Paper
• Refinery

Types of a Globe Valve:
API Globe Valve
The two sides of a globe valve are unscrewed to open and close the valve. It is most commonly used in systems to open, close, or throttle flow. A globe valve has a stem that swings up and down to control flow, as well as a disc (ball, composition, or plug) and a seat that are both linked to the valve body. The flow line is either parallel to or inclined towards the seats. A globe valve is bi-directional, meaning the fluid can flow in either direction within the valve. It allows you to control the flow and pressure as well as full cut off the flow. It can be used both manually as well as automatically.

Bellow Seal Globe Valve
A Bellow Seal Globe Valve is a control valve with a compact structure that uses bellow to seal the valve stem components. The bellow valve has a bellow within, and the stainless-steel bellows' lower end is welded to the stem to keep the system fluid from eroding it. To produce a permanent seal, the other end is positioned between the body of the valve and the cover of the valve. This double seal construction prevents leakage, as the stem packaging will prevent additional leakage even if the bellows collapse. The bellows are welded to the valve stem to guarantee consistent working efficiency and to avoid valve stem vibration caused by valve insert movement.

Forged Steel Globe Valve
Forged steel is a material created by fusing iron and carbon under extreme pressure. Forged steel has lower surface porosity, a finer grain structure, stronger tensile and fatigue strength, and more ductility than other treated steels. Steel becomes ductile and malleable when heated to forging temperature, allowing it to be shaped into the required shape with force and pressure.
Forged valves are created using a process known as forging, which involves shaping metals & alloys while they are still solid. Forged valves are known for their strength, making them excellent for high-pressure and high-temperature applications.
