Types of Water Shutoff Valves

Several types of water shutoff valves are available on the market today, including gate valves, ball valves, and globe valves. Each type has advantages and disadvantages, so choosing the right one for your home’s faucet and pipe is important.

Compression fittings and copper tubing may also be used when installing these valves.

Gate Valves

Gate valves are one of the oldest types of shutoff valves still in use today for controlling water flow. They’re typically made from brass or bronze and have a round handle that turns a gate inside the valve body.

These valves are commonly used in pipe systems, copper tubing, and supply tubes. In addition, they can be controlled using a curb stop.

One advantage of gate valves is their low cost compared to other shutoff valves used in water line systems.

However, they are prone to leakage over time due to wear and tear on their internal components, especially in high-pressure pipe systems. This can make them unreliable during emergencies when quick valve compression is necessary to prevent water damage.

Globe Valves

Globe valves are similar in design to gate valves but have a more complex internal structure that allows for greater control over the flow rate of water lines.

They’re commonly used in commercial pipe applications but can also be found in residential plumbing systems, including toilets and tubing.

One advantage of globe valves is that they provide better control over the flow rate in a pipe or water line than gate valves.

However, they can be more expensive in terms of cost and may require compression fittings for installation.

Ball Valves

Ball valves are the most popular type of water shutoff valve for home use. They’re made from brass or stainless steel and have a lever handle that rotates a ball inside the valve body to control the water flow.

These valves can be used with various types of pipe, tubing, and compression fittings. In addition, they are often used in conjunction with curb stop valves for main water shutoff in emergencies.

One advantage of ball valves is that they’re very reliable and durable for pipe systems. They’re less likely to leak over time than other types of shutoff valves, making them ideal for emergency situations when you need to turn off your water supply quickly.

Ball valves are also compatible with compression fittings and tubing and can be used as curb stop valves for municipal water lines.

Which Water Shutoff Valve is Best for Your Home?

There are several factors to consider.

These include:

• The age and condition of your plumbing system
• The location and accessibility of your main water shutoff valve is crucial in emergencies involving your pipe system. It is important to know the exact location of the curb stop valve that controls the water flow into your home’s tubing system. In some cases, compression fittings may connect the tubing to the valve.
• Your budget for purchasing and installing a new shutoff valve on the water line pipe near the curb stop is the main cost to consider.

If you have an older plumbing system, replacing your existing gate or globe valve with a newer ball valve may be more cost-effective. This will provide better reliability and durability in case of an emergency for your water line and tubing.

A new ball valve will also ensure a more efficient water shut-off process for your pipes.

If you’re building a new home or doing major renovations on your existing plumbing system, it’s worth investing in a high-quality ball valve from the start.

This will ensure that you have reliable and long-lasting protection against leaks and other plumbing emergencies. Also, consider using compression fittings for your tubing and pipes to ensure a tight seal and easy installation.

And don’t forget to install a water shut-off valve for easy access in an emergency.

Difference Between Rebuilding and Replacing a Shutoff Valve
