What Is Globe Valve?

 

An introduction to the globe valve can be termed like it is a linear motion valve that is widely employed to stop, start and throttle flow. It is widely used where the throttling of the flow is required.

Industrial globe valves show slightly higher pressure drops in comparison to straight-through valves.

Globe valves are designed with a stem that moves up and down to regulate flow inside the valve, the disk of a Globe control valve can be totally removed from the flow path or it can completely close the flow path.

It can be used for isolation and throttling services, as it shows slightly higher pressure drop they may be used where the pressure drop through the valve is not a controlling factor.

The globe valve body is designed in such a way that it forces the flow of the material to change direction within the valve itself. This change in direction creates substantial pressure drop and turbulence.

 

Parts and Components Of Globe Control Valve

 

The important parts that constitute industrial globe valve are,

 

  • Stem
  • Bonnet
  • Disk
  • Seat
  • Hand-wheel
  • Cage
  • Gland Packing
  • Inlet
  • Outlet

 

 

Advantages Of Installing Globe Valve

 

Every factory setup, the piping network requires a different mechanism to control the flow or for the smooth running of the network. The installation of good quality globe valve provides you many advantages that are listed below,

 

  • Valve can be used as a stop-check valve if disc is not attached to the stem
  • Good shutoff capability
  • Moderate to good throttling capability
  • Shorter stroke
  • Available in tee, wye, and angle patterns, each offering unique capabilities
  • Easy to resurface the seats
  • The rate at which the substance flows through the valve can be adjusted to any desired level

 

 

Application and Usage Of Industrial Globe Valve

 

The globe valve could be installed wherever the piping system needs to regulate, shut off or on, and throttle the flow of the fluid or gaseous components. The typical application and usage of globe control valve are,

 

  • Boiler Vents And Drains
  • Lube Oil Reservoir, Feed Water or Chemical Containers
  • Power Plants
  • Process Plants
  • Wastewater Plants
  • Coolant Loops
  • Lubrication Systems
  • Steam Lines
  • In Buildings Where There Is A Need For The Upstream Fluid Flow
  • Fuel Oil System Where Flow Is Regulated And Leak-Tightness Is Of Importance
  • Condenser Air Extraction
  • Turbine Seals And Drains
  • Turbine Lube Oil System

 

 

Different Types OF Globe Valve

 

Different types of industrial globe valves can be categorized based on their construction, mechanism, material, and dimensions.

We offer different types of globe control valves manufactured using different types of materials with different dimensions to cater to different manufacturing setups, factory plants, buildings, and other setups where globe valves can be installed.

The different types of glove valves are,

 

  • Bronze Gun Metal Globe Valve

The industrial globe valves are available in different dimensions and sizes that include the size of 15 mm, 20mm, 25 mm, 32 mm, 40 mm, 50 mm, 65 mm, 80 mm, 100 mm, 125 mm, 150 mm, and 200 mm globe valve sizes.

 

The flow direction of Globe valves

 

Globe valves are normally installed for keeping the pressure under the disc for application with low temperatures. This helps for an easy operation and helps protect the packing.

Globe control valves are installed in applications with high-temperature steam service so that the pressure is above the disk. If the pressure is not above the disc, the stem will contract upon cooling and tend to lift the disk off the seat.
