Irrigation Valves: Types of Valves and Installation

Will you be adding a suitable irrigation system to your yard or garden? The kind of valve you select should rely on your unique requirements. We'll go over irrigation valves in greater detail, emphasizing the two primary types: DC and electric valves. So, Put on your gardening gloves, then!

Why do we need irrigation valves in our gardens?

While some plants may do well with natural rainfall, others require more water. Irrigation valves are like watering superheroes; they ensure that every plant receives the proper amount of water. Thus, every plant goes with water! A watering irrigation solenoid valve can regulate the flow of water.  

Irrigation valves enable you to address the unique needs of each area by offering a variety of watering zones inside the irrigation system. There are various kinds of irrigation valves. Some of them are placed above the ground, some of them in the ground. 

Electric and DC valve types are frequently used irrigation valves. The main difference is that the electric one operates on alternating current, while DC valves run on direct current. Electric valves are also known for their versatility in handling a wide range of water pressures, whereas DC valves are more energy-efficient and suitable for smaller systems.

A well-designed irrigation system is especially useful when your garden has various watering requirements. Now, let's learn more about each type!

Electric Valve:

AC, or Electric valves are widely used in irrigation systems. For them to work, a reliable AC power source is necessary. Making sure the power source is dependable is crucial to avoiding disruptions in the irrigation schedule. The device is more versatile to use because it runs on alternating current and can withstand different water pressures.

Electric valves are robust and frequently resistant to corrosion because they are usually constructed of materials like brass, stainless steel, or PVC. The gadget is made with outside use and all the obstacles it may encounter in mind!

How Do AC Valves Work?

The power we rely on when using electric valves is the electromagnetic force. A valve seat, a diaphragm, and a solenoid are crucial components. Water can pass through the valve when an electric current is applied to the solenoid because it produces a magnetic field. A spring or diaphragm mechanism returns the valve to the closed position when the current is cut off, halting the flow of water.

Watering schedules can be precisely controlled thanks to electric valves. The valve provides automated and effective irrigation when it is connected to an irrigation controller because it opens and closes in accordance with the parameters. Electric valves are widely used in parks, golf courses, and agricultural fields to efficiently control water distribution due to their strength and adaptability.

It is advised to perform routine maintenance to keep the valves operating at their best. This could entail inspecting for leaks or malfunctions and cleaning or replacing the diaphragm. However, the quality of electric valves is also important.

This kind of irrigation valve is ideal if you require a broad range of water pressure for different irrigation applications! The versatility of electric valves is one of their main advantages. Therefore, your green friends are in good hands whether you intend to use the device for residential or commercial purposes.!

Pros of Using Electric Valves

  • They are more capable of handling a variety of applications and offer greater pressure;
  • For scheduled watering, this type of valve is easily integrated with irrigation controllers;
  • Control over the timing of watering;
  • Given the variety of options available, you can select the AC valve that best suits your requirements;

Cons of Using Electric Valves

  • For properly operating, AC valves need a steady supply of AC power;
  • They require more energy than other kinds of valves;

How to Install Electric Valves?

First things first, make sure you have all the tools you'll need and that the electric valve is the right size and type for your needs. Select a location for the valve that satisfies all safety and code requirements and is easily accessible after carefully reading the installation instructions that have been provided. Make sure the valve is installed in a weatherproof valve box enclosure if it is intended for outdoor use.

If the valve needs to be mounted, do so with a drill and screws. make sure that the valve is supported and aligned correctly. Attach the electric valve's wires to the irrigation controller. Electric valves normally have two wires: a positive wire and a negative wire. If the manufacturer has provided color coding, adhere to it.

Remember that in order to secure the connections, you should use the proper wire connectors. This contributes to a steady and trustworthy electrical connection. Make sure the electric valve operates correctly by testing it before completing the installation.

After testing and connecting everything, cover and secure the wiring to keep it from being harmed or exposed to the weather.

DC Valve

These devices, known as DC valves, will water your plants efficiently and provide an alternative to an AC valve. The working process of DC valves differs from AC valves since direct currents are used by them to control water flow. Because of their reputation for energy efficiency, these valves are frequently chosen in locations with poor power supplies.

DC valves work well with battery-powered controllers and are appropriate for smaller systems, whereas AC valves can supply water to a larger variety of zones. Solenoid valves, motorized valves, and proportional valves are the three most popular types of DC valves; each has special qualities and uses.

The automation process is like Electric valves. Irrigation timers are the key! The timers send signals to the valves, instructing them when to open and close. This automation ensures precise watering schedules, promoting water conservation and healthier plants.

So, if you're working in an area with unreliable power or need a more energy-efficient option for a smaller system, a DC valve is for you.

Pros of Using DC Valves:

  • They can operate without any power issues and are energy-efficient!
  • DC Valves are the best option for locations with unstable power supplies.
  • They are also more environmentally friendly because of their energy efficiency.

Cons of Using DC Valves:

  • Their use in larger systems is possible but they are ideal for smaller systems.
  • Must be used with a battery powered irrigation controller.

How to Install DC Valves?

To get started, just collect the required supplies, such as pliers or a wrench, Teflon tape, and the DC valves! Safety comes first and foremost! If old valve connections are in place, make sure they are correctly detached using the appropriate tools.

Make sure the DC valves are tightened by threading them onto the connections. Use thread sealant tape to secure a leak free connection between the valve and the adapters. Avoid over-tightening since this may harm the threads or the valve.

After the DC valves are firmly in place, make sure there are no leaks by checking the connections twice.

Final Words

In the world of irrigation, choosing the right valve is crucial for a thriving garden. DC valves are more energy-efficient than electric valves in terms of versatility. When making your choice, consider the size of your system, the availability of power, and the effect on the environment. Whichever option you select, making sure it's installed correctly and integrated with an irrigation timer will guarantee your garden gets the attention it needs.
