A slam shut off valve is designed to automatically close quickly in response to a sudden pressure drop or surge, providing safety in systems such as gas pipelines. In contrast, a standard shut off valve is manually operated to stop or allow the flow of fluid in a pipeline but does not have the automatic closure feature. The slam shut off valve is typically used in high-risk applications where rapid response is critical, while the regular shut off valve is used for general flow control.
A plug valave uses a cilindrical kind of element to shut down the flow. The ball valve uses a spherical element to sut down the flow
the hot water valve shut off valve shuts off the hot water. The cold water valve shuts off the cold water. ;()
A check valve allows for flow in one direction and a gate valve is used for positive shut off and a globe valve is used for throttling
A Knife Gate Valve is used to slice through sludge /sewerage and a gate is used fro normal positive shut off If you want to find the photo of Knife Gate Valve,you can enter to the link:http://www.kolinkcn.com/
A globe is designed for throttling and NON quick closing thus no hydraulic waves are caused. A ball type uses a ball normally stainless rather then a washer for a positive shut off
This depends what shut off valve is in question here. Where the leak is and what type of material is the shut off valve made of.
A combination valve is a pneumatically actuated shut-off valve. It is integrated into a valve housing and is typically used for blocking and releasing a flow between an inlet and an outlet

Is the water shut off valve leaking in your home?
What to use to solder a shut off valve
Yes, the shut off valve is leaking through the stem.
To fix a leaking shut off valve, you can try tightening the packing nut or replacing the washer inside the valve. If these steps don't work, you may need to replace the entire shut off valve.
