Valves are the heart of an irrigation system. To simplify valve installation and maintenance and ensure long-lasting system performance, it’s important to understand how these components work.

In this video, we’ll identify the different components of a valve, including the parts visible on the outside as well as those on the inside. We’ll also show you how water travels through a valve and explain the forces that cause a valve to open and close.

It's 3:30am and I couldn't quite fall asleep until I knew exactly how the valve worked. Excellent video!

I know very little about sprinkler systems. One of our valves was leaking and doing the flush in this video fixed my problem. Thank you!

[Sully_On_Maui]

Thanks guys! You helped me troubleshoot my system. $9 part and it works perfect!

[SquadUp]

Awesome now I know what's wrong with my valve. I got water at the bleeder but no water to the heads. All other zones work fine. Huge thanks

starting an apartment maintenance job in 8 hours. I told them I have extensive irrigation experience. Now I know everything lol.

[LordHog]

Great explanation of how these values work. Thanks

[Anchor]

Very clear explanation, thanks so much.

Fantastic video my next valve purchase will be a hunter!

[westvalley]

Wow, love the high tech video. Best one online...lot of terminology and explanation. Still don't quite get the pressure gradient and channels sequence...more arrows please...

[CarlosCastro-htxl]

Thank you for the help greatly appreciate it!

My IQ just increased by a couple of points. Thank you.

Would low water pressure situations affect the PGV? Would it remain closed?

[JanTijmes]

What's a good setting for the diaphragm, the screw in the middle of the bottom?

[e.a.p]

I used Rainbird’s DV100 for many years but switched to Hunter in 2021, so far Hunter has been very reliable.

If i turn open the cylinoid and open the bleeder at the same time, what will happen?

[yyymmmddd]

Does solenoid need to be energized all the time we want water to flow or is it enough to energize it for a few seconds until the chamber changes pressures?

[txtasosxt]

I took apart mine, cleaned every part (had nothing to clean though), played with the exhaust valve and tried to manually turn it, but mine won't work. If the main flow is on, it won't open. If I open it and then close the main flow, the valve will open. I can then open the main flow and water will flow. Turning it off also works.

During the winterization of the system, the blow-out port should be on inlet side or outlet side?

[nationalshiningvision]

Interesting fact and very informative, thank you sir!

[RayanMufti]

Would a larger metering port break the system?
