What are the different types of shut off valves?
These Are the Types of Water Shutoff Valves
- Washer valves. Most of the water shutoff valves in your home will probably be of this type.

What is the best type of water shut off valve?
Ball valves are perhaps the most reliable type of valve and are commonly used for main water shutoffs and for branch line shutoffs. Like gate valves, a ball valve is designed as an all-or-nothing valve—they should be either fully open to allow full flow, or fully closed to stop all water flow.
How many types of water valves are there?
In addition to ball valves, they can include cartridges, ceramic disc valves and compression valves. Cartridge valves are designed with a movable stem that can be raised or lowered to regulate flow, inside a plastic cartridge. Two-handle faucets often have separate cartridge valves for the hot and cold water.
