What are Gate Valves?

Gate valves work exceptionally in many environments. There are many advantages of gate valves due to their efficient structure. People often mistake gate valves vs. Globe valves. The gate valve working is unique and differs from other valves. This ultimate gate valve guide covers everything you need to know about gate valves. The working types and applications of gate valves are described below. Let’s check out what is a gate valve.

What is a Gate Valve?

A gate valve is a plumbing product that controls the fluid flow through pipes. Consider having a pipe that brings water, and you want to control when water flows and stops. In conditions like these, gate valves are the most suitable option.

One of the best gate valve features is their excellent seal-on closure. This property ensures no liquid or gas leaks when the valve gets closed. There are many types of gate valves for water supply and other applications.

Gate valves apply to house water pipes, big pipelines for transport, and power plants. The ideal usage of a gate valve is in regulating gases or liquid flow.

Working of Gate Valves:

Gate valve working is like opening and closing a door to control the flow of water or air in a pipe. Consider having you have a giant door inside the pipeline. You can lift it to allow flow or lower to stop it. The gate valve works similarly to this mechanism.

Open Position: The flow can pass through” when” the gate valve opens. The “door” inside the valve, called the gate, lifts, creating an open pathway for water or gas to move through the pipe.

Closed Position: When we want to stop the flow, we close the gate valve. The gate lowers, blocking the pathway inside the valve. Nothing can pass through when the gate is down, and the entire flow stops.

We use a handle to control the gate and move it up or down. Turning the handle lifts or lowers the gate, like a door opening or closing a door. It’s like a switch that we can use to control the flow in pipes. In our homes, in big pipelines for oil and gas, or in different industries, they manage the movement of fluids.

Types of Gate Valves:

Here are the gate valve types.

Rising Stem Gate Valve:

The stem grows and lowers on turning the handle in rising stem gate valves. When we open the valve, the stem stretches and straightens. At the same time, the branch lies downwards when the valve is closed. This mechanism enables us to understand the valve status by looking at the valve design.

Non-Rising Stem Gate Valve:

The stem type in this gate valve does not move from its place. Instead, it remains still while the gate inside the valve changes its position from up to down. The best perk of having non-rising stems is their less space consumption. A non-rising stem gate valve is ideal for small places where we cannot install giant valves due to lack of space.

Wedge-Shaped Gate Valve:

The gate has a wedge shape in this type. It means the gate wedges between the valve seats when it lowers. They provide a very secure shut-off. They are excellent where a tight seal and resistance to high pressures are necessary.

Bypass Gate Valve:

Bypass gate valves have a unique structure containing an extra passage. This additional duct works like a substitute when we close the gate valve. The fluid can flow and continue its way through a closed valve via this bypass.

The primary purpose of a gate valve with a bypass is to maintain continuous flow. It flows even during maintenance or repair activities on the gate valve itself. Opening the bypass allows fluid to move through the system. At the same time, the gate valve works without interrupting the flow.

Gate Valve Applications:

Here are a few of the most helpful gate valve applications.

Applications of gate valves

Water Supply Systems: 

Gate valves regulate water flow through pipes in water supply systems. There are separate types of gate valves for water supply systems. They have immense switch-like structures that can be on or off at different places, like our homes and schools. When you turn the tap on to wash your hands, a gate valve helps control water flow through the pipes. It is one of the best gate valve applications.

Gas Pipelines: 

Gate valves are crucial in gas pipelines that carry natural gas to homes for cooking and heating. They help regulate gas flow, ensuring the correct amount reaches each place.

Power Plants: 

In power plants, gate valves serve the duty of regulating steam and water flow. Steam generates electricity, and gate valves take steam to the desired locations with excellent carrying ability. Similarly, you can turn off the flow from the gate valve when unnecessary.

Irrigation Systems: 

Gate valves play a role in irrigation systems present in farming. It is among the best gate valve applications. They control the flow of water from within fields during agriculture. They equalize the water supply for the growth of healthy crops.

Oil and Gas Industries: 

Gate valves help in controlling the flow of oil and gas. They enhance safety and bring them to their destination with great care.

Chemical Processing: 

Gate valves in chemical plants control the chemical flow during the manufacturing process.

Water Treatment Plants:

Water treatment plants use gate valves to regulate water flow during purification. They ensure clean and safe water reaches our homes for drinking and other activities.

Sewage Systems: 

Gate valves in sewage systems control wastewater flow and prevent any backflow.

Gate Valve Installation:

Follow these step-by-step instructions for the installation of gate valves.

Materials Needed:

  • Gate valve.
  • Pipe wrench or adjustable wrench (to tighten the valve).
  • Pipe joint compound or Teflon tape (for sealing).

Steps to Install:

Gate valve installation needs careful handling of the product and tools. To start the installation, choose a specific location and cut off the water or gas supply at that point. This step is essential for safety.

Check the gate valve to ensure it fits the size of your pipe. To get the best performance, ensure the valve is free of dirt or debris.

Now, put a small amount of pipe joint compound or wrap Teflon tape around the threads on both ends.

The valve should face where you want it to turn to open or close the valve. Screw one end of the valve onto the pipe, turning it clockwise until it’s snug. Check if it’s straightforward with the help of a level.

Gently turn the gate valve handle for testing to check if it opens and closes smoothly. If the valve works well, you have successfully installed it correctly.

Gate Valve Maintenance Guide:

Here is the gate valve maintenance guide:

  • Inspections: Gate valve inspection refers to checking for the signs of damage or leaks. Look for rust, corrosion, or any loose parts over a certain period.
  • Lubrication: Lubrication is essential for gate valves to smooth operating parts’ movement. Use a suitable lubricant for the stem and other moving components. Consider the manufacturer’s advice while selecting a lubricant for your product.
  • Cleaning: Cleaning is one of the most accessible and primary means to maintain your gate valve. Regular cleaning of surroundings and inner structure ensures optimal performance. It helps remove debris or other particles from disturbing the working of the gate valve.
