Globe Valves

What are Globe Valves?     

Globe valves, a type of control valve, are used to stop, start and regulate the flow of media through a pipe. From the outside, they have a spherical body design. And inside, a plug-like disc sits on the end of a threaded rotating stem to raises and lowers to control media flow. Globe valves are part of the linear motion valve family, which means that the valve mechanism moves along a straight line.

How Does a Globe Valve Work?

Named for their spherical body shape, globe valves bodies are separated into two halves by an internal baffle. The seat on the globe valve disc can be screwed in to close the valve. Most automated glove valves use smoother stems not threaded ones. And use an actuator assembly to open and close.

Gate Valves

What are Gate Valves?     

Gate valves are linear motion valves that are used only to start or stop media flowing through a pipe. They are shutoff valves instead of control valves, since they are not ideal for throttling.

Generally, they are designed with a flat or wedge-shaped disc on the end of a threaded stem, which is turned via a wheel and raises and lowers to operate the valve. Gate valves provide a tight shutoff, and  are commonly used for isolating media. Because they do not force media to change course (as in a globe valve) , gate valves cause little pressure drop.

Gate and globe valves often work in tandem inside a piping system. Gate valves can be designed with rising or non-rising stems, which is helpful for space optimization.


How Does a Gate Valve Work?

When a gate valve is activated, the stem will turn clockwise or counter clockwise to raise or lower the disc inside the pipe. In its closed position, the disc lodges between the seats in the base of the valve, providing a full stop at a right angle to the media flow. The disc can be shaped like a wedge, knife or parallel panel.


Ball Valves

What are Ball Valves?     

Unlike gate or globe valves, ball valves are a type of quarter-turn valve that utilizes a bead shaped ball with a hole in the middle to control the flow of media. Called a bore or port, the hole in the middle of the ball allows media to pass through the valve body when opened, and is rotated 90 degrees to stop flow. The port is aligned perpendicular to the valve body in the closed position.


How Does a Ball Valve Work?

Ball valves are a type of quarter-turn valve which use a hollow, perforated and pivoting ball to control the flow. It opens when the hole of the ball is in line with the flow and closes once pivoted 90-degrees by the valves handle. The handle lies flat in alignment with the flow whilst open and perpendicular once closed. This allows for easy visual confirmation of the ball valves status.



Pros Cons
Globe Valves Can regulate media flow.

Can handle high-pressure, high-temperature, corrosive or viscous media

Create a high-pressure drop

Introduce resistance to media flow

Gate Valves Economical option for on/off control


Offer little resistance to media flow

Not ideal for regulating media flow

The sustained flow of media in a partially open position

Can cause water hammer

Prone to leaks: less durable than ball valves

Ball Valves Long lasting and durable

Versatile media compatibility


Provide fast cycle speeds

Good for high-pressure, high-volume applications

Offer little resistance to media flow

Not ideal for regulating flow

Fast cycle time can lead to water hammer
