Simple & functional

Attached to a 3-way splitter on the output from the water pump. The rotary function does not have too much slack, so sagging is not a problem.

Excellent quality workmanship

These are extremely high quality valves for water cooling loops and the blue metallic paint job is very well done.

It’s a valve

The valve works. It is a ball valve. I put a compression fitting on one end (tube end) and a cap on the other end. I used this to create a fill line in my loop. It made my life better. It would probably make your life better.

Before you install it

This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: leak test before power. Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.

Questions people ask about this part

Answers specific to B-DV-CEV2-BK. If yours isn't here, ask — we'd rather talk you out of the wrong part than sell you one.

What does this part fit?
Compatibility for this part is listed in the compatibility notes on this page. Parts like this are machined to a specific hardware layout, so send us your exact model and we will confirm it against part number B-DV-CEV2-BK before you order.
Is it in stock, and when will it ship?
Yes — in stock in Boise, Idaho. Orders placed before 2:00 PM MST on a business day ship the same day — we do not ship weekends or US holidays. Overnight delivery is available at checkout.
Can I return it if it turns out not to fit?
Yes. Returns are accepted within 30 days and are easy to start in the support center.

Will I pay import duties or customs charges on delivery?
Not on a US order. US import duties and tariffs are already included in the price, so nothing is collected at the door and there is no brokerage fee. Orders shipped outside the US may owe that country's customs fees and duties.
