Globe Valve: The Ultimate FAQ Guide
Learning standard information about globe valves can help you choose the most suitable one for your specific applications.
This scholarly article surely helps you learn about the functions, benefits, advantages, and many other points to consider before purchasing.
Take your time reading!
What is Globe Valve?
The globe valve starts and regulates the flow or pressure of the fluid. It also functions as absolute flow shut-offs.
Globe valves have rising stems and a large screw and yoke design outside.
In a low-temperature operation, it regulates the flow pressure under the disc. On the contrary, in high-temperature applications, it controls the pressure in the above disc directions.
What are the Advantages and Disadvantages of Globe Valves?
- Easy to resurface the seats
- Average throttling capability
- Shorter stroke than gate valve
- Excellent shut-off capability
- It can be used as a stop-check valve
- Available in different patterns with extraordinary capabilities
- Throttling flow under the seat
- Greater force is needed to seat the valve
- Requires larger actuator to place the valve
- Higher pressure drop than gate valve
- Heavier weight than other valves
What are the Typical Applications of Globe Valves?
- Turbine seal and grains
- Feedwater and extraction drain systems
- Condenser air extraction and chemical feed systems
- Regulated flow and leak tightness in fuel oil systems
- Boiler vent and drains
- Heater drains
- Central steam vents and drain
- High-point vents and low-point drains
- Turbine lube oil systems
- Regulated cooling water systems
What are the Body Designs of Globe Valves?
Angle Pattern Globe Valve
The angle pattern is designed with 90 degrees angle. It happens that the fluid flows 90 degrees turn.
This pattern has a bit lower flow coefficient compared to a wye pattern globe valve.
Angle pattern globe valve can operate stagnating flow effects.
Tee Pattern Globe Valve
The tee pattern is the most standard type of globe body valve.
Its horizontal setting seats make the disk and stem move right angle to the horizontal line.
A type of body pattern that has the lowest flow coefficient and more significant pressure drop.
The globe valve tee pattern is practical in severe throttling operations.
Wye Pattern Globe Valve
This type of body has about 45 degrees angle.
This pattern provides an aligned flow path with lesser flow resistance.
The wye pattern is broadly applied for periodic throttling or start-up performance.
What are the Functional Parts of Globe Valve?
There are various disc designs for globe valves, such as composition disk, ball disk, and plug disk.
*Composition disk is formed for non-metallic and rugged applications. This disk assures tighter closure.
*Ball disk is applicable for low temperature and pressure systems. This disk functions as a flow controller and starter.
*Plug disk operates better throttling than the other disk designs.
The seat of globe valves can either be separated or screwed into the body.
This part helps prevent the system pressure from forming as opposed to opened valve packing.
A stem is a globe valve part that connects the disk and the stem.
It has the T-slot that slides over the stem and the disk nuts designed to screw into the stem.
Aside from disk, seat, and stem, the outer parts of globe valves include bonnet, body, and a handwheel.
How Does a Globe Valve Work?
Turning the handle allows the disk to raise or lower.
When you shut off the fluid flows, fully lower the disk while raising it makes the fluid flow at its extreme rate.
Raising the disk lesser the maximum level makes the fluid flows to the vertical disk travel equally.
Is Globe Valve Unidirectional?
Yes, the globe valve is unidirectional because it functions as the medium flows in one direction.
Are Globe Valves Expensive?
The globe valve with a similar size to the gate valve is more expensive.
But has lasting service and value, especially in throttling situations.
How Do You Install the Globe Valve?
It is essential to follow the exact way installation of globe valve to avoid damages and premature wear. Below are the main points of the globe valve installation.
- Take out debris or packing in the valve.
- Make sure the internal part of the valve is free from moisture or water.
- Assist the valve in preventing long-run damages
- Ensure the operating room of the valve
- Completely dry the valve by closed to open cycle
- Gradually tighten the flanged bolts diagonally
- Check the installed flanged and bolts by moderately raising the internal pressure.
- Check also if the valve is appropriately sealed.
- Heighten the internal pressure to function level and recheck.
Where are Globe Valves Installed?
The globe valve is placed on the pressure side or inlet under the seat. The valve is installed parallel to the media flow direction.
What Happens if a Globe Valve is Installed Backwards?
If the globe valve is installed backward, the upstream fluid flow pressure will be on the top of the plug-which is on the wrong side.
Popping or opening the valve while overcoming the pressure is caused by the improper installation of globe valves.
Are Globe Valves Good for Isolation?
The globe valve is ideal for throttling and isolation.
Functions to control the fluid flow in pipelines.
How Do You Know Which Way the Globe Valve Is?
You can observe the globe valve body to know or determine the flow direction.
There are valve arrows that indicate fluid flow direction.
Is Globe Valve the Same as Ball Valve?
The globe valve and ball valve have the main difference, which includes its closing ways.
The globe valve operates with a plug or stem and closes as opposed to the flow. It is applicable to flow regulations.
The ball valve uses a gate or ball that locks across the flow. A ball valve is suitable for on and off operation without pressure drop.
How to Maintain the Best Operating Globe Valve?
- Inspect regularly the valve. Check out the gland to ensure no noticeable wear. You can also inspect if the valve is leaking.
- For bedding seat issues, cycling the valve is recommended.
- Lubricate the crossbar, including the spindle, if necessary.
- Gradually tighten the gland bolts. Overtightening can damage the glands.
- Replace the packing gland if leakage occurs.
Why Does the Globe Valve Fail?
The globe valve typically fails because of plug and seat misalignment.
It happens when the flow forces the plug out the alignment of the seat.
If the misalignment occurs, the plug’s bottom edge connects to the seat ring and stops the plug from moving to the proper position.
Because improper plug-to-seat contact, it causes substantial bending.
How Do You Repair a Globe Valve That Leaks?
Step 1. Turn Off Water Supply
Turn off the water using the shut-off valve. Release pressure by opening the valve.
Step 2. Remove the Globe Valve
Undo the bolts that support the globe valve body into a bonnet using a pipe wrench. Uproot the valve from the bonnet using a screwdriver.
Step 3. Check Out and Replace the Packing Material
Examine the packing washer to see if there is rust or a loose fit. Replace the damaged washer with a new one.
Inspect also the seat and the gasket of the valve if there is leakage.
Step 4. Rebuild the Globe Valve
Place the new packing washer to the globe valve and attach it again to the bonnet.
Make sure that all bolts are gradually tight.
Step 5. Put Back Water Supply
Restore the water and free air from the pipes.
Check the valve for leakage by testing the operation.
How Do You Know If the Ball Valve is Open or Closed?
- Open – the handle is perpendicular to the valve
- Close – valve’s handle is parallel to the valve
Is the Globe Valve a Control Valve?
A control valve has various common types, including the globe valve
Does a Globe Valve Reduce Pressure?
Yes, if the globe valve is in a total open position, the pressure reduces.
When it’s fully open, the fluid flows in another direction through the valve.
What are the Factors to Consider for Globe Valve Sizing?
- Flowing Conditions
The globe valve has a typical size of about 60-80% of valve open. If the fluid flow exceeds its capacity can cause a higher pressure drop.
- Temperature and Pressure Ratings
It is recommended that sizing the valve pressure, you also have to consider the operating temperature.
- Process Media
Consider the type of end connections for piping sealing performance. Knowing the process media for sizing the globe valve is important.
Globe valve is an excellent choice for plant piping solutions.
When you plan to buy a globe valve, always think or consider important factors.
Always make sure the globe valve installation is correct and do regular maintenance for a long time of usage.
