Globe Valves: Maintenance, Applications and Uses


What is a Globe Valve?

Globe valves (GV) are mostly in-demand in various Industries. A common use of Globe Valve is to control the flow of fluid in a pipeline and adjust the Gaps between the Globe Shaped Plug and the Ring Seat. It consists of a movable disk-type element and a ring seat in a spherical body. When Compared to other Valves, Globe Valve doesn’t Leak Much because of the Right Contact between the Disc and the Ring. The Disc available on a globe valve can be removed from a flow path.


Globe Valves opening and closing is done by an actuator because the plug of a globe valve is connected to a stem that is operated by a screw. Basically, Globe valves are designed with a stem that can move up and down to regulate the flow inside the valve. Seats of this valve are designed in a plane parallel or inclined to the line of the flow. These types of valves are most commonly used to throttle, open or close flow in a piping system.

A Brief Information on Ball Valves Body Parts and its Types

Advantages of Globe valves:

·         The opening-closing time of a globe valve is shorter.

·         Globe Valve (GV) contain positive shut-off

·         Provides Good throttling Capability.

·         Doesn’t Leak much as compared to other valves

·         Has a Shorter Stroke

·         Easy to machine or resurface the seats.

·         Available in Different Types with each offering unique Capabilities.

·         The body ring seating surface process is easier.

·         With disc not attached to a stem, the valve can be used as a stop-check valve

Disadvantages of Globe Valves:

·         Non-Benefits a Globe Valve has it that it requires a great force or a large actuator to seat the Valve

·         Higher Flow Pressure and to close globe valves under high pressure, it requires a larger amount of force or an actuator with a large torque

·         Other Disadvantages of a Globe Valves is that it has a High-Pressure Drop

Maintenance of Globe Valves

The packing of the Globe valve is subjected to depreciation i.e., wear and tear and thus needs to be changed after some time as the sealing quality will reduce. However, continuous opening and closing of the valve leads to damage to the metal of the valve seat. Lapping paste is applied to the seat to make the surface smooth and remove any clearances and also helps in damaging the product.

Applications & Uses of Globe Valve:

Globe valve can be used as a non-return valve as it is used in applications where variable pressure is required in the pipeline such as emergency line etc. The type of valve where the disc is not attached to the spindle is called screw-down non-return valve. This type of valves is used for preventing back flooding. The type of valve wherein the disc is attached to the spindle is known as the screw lift type valve.


Applications of GV are as Follows:

·         Applied in cooling water systems where the flow needs to be regulated

·         Used in Fuel oil system where the flow is regulated and leak tightness is of importance

·         Chemical Industries to provide a smooth flow of fluid, materials, slurries

·         Petrochemical Industries

·         Turbine seals and drains

·         Paper Manufacturing Industries

·         Shipping Industries

·         Steel Factories

·         Turbine lube oil system and others

Orbit Valves & Their Application

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by open, closing, or partially obstructing varied passageways. Valves is technically fittings, however, it is typically mentioned as a separate class. In an associate open valve, fluid flows during a direction from higher pressure to lower pressure. The word springs from the Latin valve, moving a part of a door, successively from the valve, to turn, roll. Orbit valves manufacturer in Kanpur . The simplest, and the extremely ancient, valve is solely a freely hinged flap that drops to hinder fluid (gas or liquid) flow in one direction, however, is pushed open by flow within the wrong way. this can be referred to as a check valve because it prevents or "checks" the flow in one direction. trendy management valves might regulate pressure or flow downstream and operate subtle automation systems. Valves have several uses, together with dominant wat
