What Is an Angle Valve?

When learning about any type of valve, it is vital to know the types and uses them. There are questions to ask yourself for the best knowledge on anything you are installing. While operating an instruction manual, you need to know what to do with an angle valve.

In simplest terms, an angle valve is a valve that controls the intake or output of a liquid or gas. These valves are used in the plumbing industry. This valve commonly has an oval or twisting knob, like on a toilet. This knob is what activates the intake or outtake amount.

Learning about angle valves can become slightly confusing at first. Many questions may occur when learning how to use it, its purpose, or how to fix it. All can be very difficult if you are trying any new project or simply trying to fix your angle valve in a cost-friendly way.

What Is Angle Valve Function?

The purpose of the angle valve is to control the intake or output. It is commonly a shut-off valve for water, allowing the water to turn off without shutting off the entire water supply.

Where Are Angle Valves Used?

Angle valves are in many places in your home. They are in the plumbing lines. They are found being used as elbows to move water along to a different pipe. It permits more space for the water to move. They can be used for numerous different valves like a shut-off valve, needle valves, and stop check valves.

What Is an Angle Valve In Plumbing?

When plumbing, an angle valve controls the intake and outtake of water. These are used to turn off the water from going to various appliances. By turning the angle valve, it turns off the water from that appliance.

Let’s say you are fixing your dishwasher. By turning off the water, it allows you to swap out your dishwasher. There will be no water flying throughout your kitchen. By twisting the angle valve and turning off all the water, you prevent getting sprayed in the face with water and flooding your entire kitchen.

How Do You Fix an Angle Valve?

This repair tasks a fair bit of time, roughly about 1/2 of a day. If the repair feels like the project is too big for you to fix, call your local plumber. They can help. For this project, you will need:

  • Two wrenches
  • Supply line

Step One: Remove Your Old Angle Valve

Turn off the water and then disconnect the water line from the angle valve. Use one wrench to get a hold of the compression nut, the other to grip the angle valve. Only turn the wrench holding the compression nut.

Step Two: Replace the Supply Line

Use a new reinforced line and replace the angle valve.

Step 3: Reattach the Line to the Valve

Remove the compression nut from the valve, then place the compression nut over the nipple of the supply line. Tighten the compression sleeve to the valve using the wrenches. Remember to tighten just the compression nut.

How Do You Connect Angle Valves?

Connect the compression nut over your pipe, then slide the valve onto the pipe. Begin tightening with your fingers, then use two wrenches. One wrench will tighten the compression nut. The other wrench will hold the valve in place. While doing this, be sure not to over-tighten the compression nut to the valve because this will strip the nut. It may also cause the valve to leak.

What Are the Different Types Of Valves?

There are different types of valves, but they all serve the same purpose, to regulate flow. However, they are all used differently.

  • Ball Valve: is a 1/4 valve on a pivoting ball. The pivoting ball has a hole through the ball allowing air or liquid to pass through the ball when turned. The ball valve is commonly used in the oil industry.
  • Butterfly valve: a valve with a disk controlling flow. It is commonly used when space is limited.
  • Check valve: has two ports, one non-reflux, and one reflux valve. Check valves are usually installed in piping to prevent backflow.
  • Gate valve: is a valve that is twisted to restrict flow. This is typically used for your outdoor gardening hose. It is perfect for limited space.
  • Knife gate valve: is similar to a gate valve. It is commonly used with more toxic materials.
  • Globe valve: has a plug to seal the hole within the valve. This is commonly used in factory piping.
  • Needle valve: is perfect for a precise flow of very low flow materials.
  • Pinch valve: uses a pinching effect to restrict flow. Commonly used with toxic, or dangerous products.
  • Pressure relief valve: is a safety device to relieve pressure in the event of overpressure.

How Do You Replace an Angle Valve?

Turn off the water that connects to the angle valve. Loosen the compression nut using a wrench while holding the angle valve in place with another wrench. Once loose enough, finish loosening with your fingers. Remove angle valve and compression nut.

Take the new compression nut and slide it over the pipe. After that, slide it on the valve. Tighten the compression nut on the valve using your fingers. Then, tighten it using the wrench. Hold the valve in place with one wrench and tighten the compression nut using the other wrench. Do not over tighten as this may cause leakage.

Replacing and learning about an angle valve may seem complicated, but it is not. It is a simple process that can easily be done within a few minutes. If at any point you feel that the project is too overwhelming you can call a local plumber who may be able to solve your problem for you.
