Types of Shut-Off Valves
In plumbing systems, shut-off valves are essential components that allow the user to control the flow of water to a specific outlet or appliance. There are several types of shut-off valves available on the market, each with its own unique features and functionality. Understanding the different types of shut-off valves can help you choose the right one for your specific needs. Let’s take a closer look at four common types of shut-off valves: threaded valves, quarter-turn ball valves, compression fitting valves, and SharkBite push-on fitting valves.
Threaded Valves
Threaded valves are a popular choice for shut-off valves due to their ease of installation and compatibility with a wide range of pipe sizes and materials. These valves feature male and female threads that allow them to be screwed onto the corresponding threads on the pipe or fitting.
Quarter-Turn Ball Valves
Quarter-turn ball valves, as the name suggests, have a ball inside the valve body that is turned 90 degrees to control the flow of water. These valves are known for their quick and easy operation, requiring only a quarter turn of the handle to open or close the valve.
Compression Fitting Valves
Compression fitting valves use a compression nut and ferrule to create a watertight seal around the pipe. The compression nut is tightened onto the valve body, compressing the ferrule against the pipe and creating a secure connection.
SharkBite Push-On Fitting Valves
SharkBite push-on fitting valves are a popular choice for DIY enthusiasts due to their simplicity and ease of installation. These valves feature a push-on connection system that eliminates the need for soldering or special tools. The valve is simply pushed onto the pipe, creating a secure and leak-free connection.
How Threaded Valves Work
Functionality
Threaded valves work by using male and female threads to create a tight seal between the valve and the pipe. The valve consists of a valve body with internal threads, a sealing element such as a rubber washer, and a handle for turning the valve on or off. When the handle is turned, the threads on the valve body and the pipe engage, creating a watertight seal and allowing or blocking the flow of water.
Installation Steps
- Ensure that the pipe and valve threads are clean and free of debris.
- Apply a thread sealant or plumber’s tape to the male threads on the pipe.
- Screw the threaded valve onto the pipe by hand, ensuring that it is turned in the correct direction for opening and closing.
- Use a pipe wrench or adjustable wrench to tighten the valve further, ensuring a secure connection.
- Test the valve by turning the handle to the open position and checking for any leaks.
How Quarter-Turn Ball Valves Work
Functionality
Quarter-turn ball valves use a lever or handle to control the flow of water. Inside the valve body, there is a hollow ball with a hole in the middle, known as a bore. When the handle is turned, the ball is positioned so that the bore is either aligned with or perpendicular to the pipe, allowing or blocking the flow of water.
Installation Steps
- Ensure that the valve is the correct size and type for your application.
- Determine the correct orientation (open or closed) of the valve based on the direction of the handle.
- Use a pipe wrench or adjustable wrench to tighten the valve onto the pipe, ensuring a secure connection.
- Test the valve by turning the handle to the open position and checking for any leaks.
How Compression Fitting Valves Work
Functionality
Compression fitting valves create a watertight seal by using a compression nut and ferrule to compress the pipe against the valve body. When the nut is tightened onto the valve body, it compresses the ferrule, creating a secure connection and preventing water from leaking.
Installation Steps
- Prepare the pipe by cutting it to the desired length and ensuring that the ends are clean and free of burrs.
- Slide the compression nut and ferrule onto the pipe, with the ferrule positioned closest to the end.
- Insert the pipe into the valve, ensuring that it is fully inserted.
- Tighten the compression nut onto the valve body by hand until it is snug.
- Use a wrench to tighten the nut a quarter turn further, ensuring a secure connection.
- Test the valve by turning the handle to the open position and checking for any leaks.
How SharkBite Push-On Fitting Valves Work
Functionality
SharkBite push-on fitting valves utilize a unique push-on connection system that allows for easy and secure installation without the need for soldering or special tools. The valve features a collet with stainless steel teeth that grip onto the pipe when it is pushed into the fitting, creating a watertight seal.
Installation Steps
- Prepare the pipe by cutting it to the desired length and ensuring that the end is clean and free of burrs.
- Slide the SharkBite depth tool onto the pipe to mark the correct insertion depth.
- Push the valve onto the pipe until it reaches the marked depth, ensuring that it is fully inserted.
- To remove the valve, use a SharkBite removal tool to push in the collet and pull the valve off the pipe.
- Test the valve by turning the handle to the open position and checking for any leaks.
Steps to Repair a Shut-Off Valve
Over time, shut-off valves may develop issues such as leaks or a failure to fully shut off the water flow. Repairing a shut-off valve can help restore its functionality and prevent further damage. Here are the general steps to follow when repairing a shut-off valve:
