Apollo Valves FAQ: 10075806, 94ALF Ball Valves, and 3/4 Check Valve Questions B2B Buyers Actually Ask

I've been buying valves and fittings for a mid-sized plumbing supply operation for the better part of seven years. Not the biggest account, not the smallest—roughly $180K a year in brass, PEX, and backflow gear across maybe 15 vendors. So when people ask me about Apollo Valves part numbers or whether a well pump needs a check valve, I answer from spreadsheets, not from a catalog.

Here's what I actually get asked, and what I tell people.

Q1: Who is Apollo Valves, and does the brand name actually matter for procurement?

Apollo Valves is the flagship line made by Conbraco Industries out of Matthews, North Carolina. They've been making ball valves, check valves, relief valves, backflow preventers, gate valves, and PEX fittings domestically for a long time.

Does the brand matter? Yes, but not for the reason most people think. It's not that an Apollo 3/4" ball valve is magic. It's that when you're spec'ing for a job and the inspector, the engineer, and the end user all recognize the name, you skip a whole category of arguments. Documentation is easier to pull. Warranty claims go through a known channel. That's worth something on a cost sheet even if it never shows up as a line item.

That said—if you're buying 500 of something for a closed-loop system where nobody downstream is checking specs, the brand premium is harder to justify. My experience is based on maybe 200 mid-range commercial orders. If you're working in ultra-budget residential or high-spec industrial, your math will look different.

Q2: What is Apollo Valves 10075806, and when do I stock it?

I'm going to be straight with you: I don't carry every Apollo SKU in my head, and 10075806 is a part number I'd want to double-check against the current Conbraco catalog before I ordered it. Part numbers on the Apollo side get revised, and the 8-digit numbers sometimes map to old stock vs. current production.

Here's what I actually do—and I'd recommend this for any Apollo number you're not 100% sure about:

• Pull the current catalog PDF from the Apollo site or your distributor's portal.
• Search the number and confirm the body material, end connection, and pressure rating.
• Cross-check against what the job spec actually calls for.

Three steps. In that order. Skipping step one is how you end up with a box of valves that meet the size but not the spec, and a return freight bill you eat.

On stocking: I keep high-rotation Apollo numbers on the shelf—common brass ball valves, standard check valves—and order the oddball sizes as-needed. Stocking a slow-moving Apollo SKU ties up cash for months.

Q3: Is the Apollo 94ALF ball valve a safe pick, or are there situations where it's the wrong call?

The 94ALF is a ball valve in the Apollo line—widely used in water and HVAC applications. For most standard plumbing jobs, it's a workhorse. Threaded ends, solid body, standard pressure class.

Where I'd pause before spec'ing it:

• Extreme temperature swings—not that the valve can't take some, but you want to match the seat material to the application.
• Media other than water or glycol. Corrosive chemical lines are a different conversation.
• Any job where the spec sheet calls for a specific certification or actuator setup the 94ALF doesn't ship with by default.

Honestly, the 94ALF works for the overwhelming majority of what we move. But the failure mode I've seen over the years isn't the valve failing—it's the buyer assuming "ball valve is ball valve" and ignoring the seat material or end connection. That's on the buyer, not Apollo.

Q4: When picking a 3/4 check valve, what actually drives cost?

Three things: body material, connection type, and pressure class. In that order. The brand is a distant fourth unless certifications are on the line.

Here's the misconception I keep running into—people think a premium check valve costs more because it's "better." The reality is often the reverse: valves that survive ten years in the field can charge more because they've been field-proven. The causation runs the other way from what buyers assume.

What I track in my cost spreadsheet for a 3/4" check valve:

• Unit price (obviously)
• Freight if it's not on a pallet with other orders
• Return rate over 12 months (this one hurts)
• Labor to swap a failed unit during warranty

That last line is the one nobody quotes. A cheap valve that fails 4% of the time costs more than a mid-range valve that fails 1%—once you price in the callback.

Q5: How does an air compressor parts manual relate to valve selection?

If you're maintaining compressors, the parts manual is your valve reference. Compressors use check valves on the discharge side, safety relief valves, and often a pilot valve or unloader. The manual tells you the exact part number, and the manual is the only source I'd trust for that.

Here's a mistake I made early on: I tried to cross-match a compressor check valve to a generic plumbing check valve based on size and thread. It fit. It threaded on. It also failed in six weeks because the cracking pressure was wrong for the compressor's duty cycle.

Looking back, I should have just pulled the manual and ordered the OEM spec. At the time, I was trying to save maybe $14 a unit. We lost more than that in labor and a return.

So—manual first, cross-reference second. Never the other way around.

Q6: Does a well pump have a check valve? (And why do buyers keep missing this?)

Yes. Almost always. A submersible well pump has a check valve built into or mounted right at the pump discharge. Many setups run a second check valve at the tank to protect against backflow if the first one fails.

Why this trips people up: they see the check valve at the tank, assume that's the only one, and then wonder why water pressure drops when the pump cycles. Nine times out of ten, the downhole check valve is leaking back.

The cost angle is the one people miss. A $30 check valve failing can take out a $900 pump because of the short-cycling it causes. I've seen it happen on three different customer accounts. The valve is the cheap part. The pump is not.

If you're speccing well pump accessories for a distributor or contractor account, add the downhole check valve to the quote even if they didn't ask. It saves everybody a callback.

Q7: Is a "close enough" substitute ever actually the cheaper option?

Rarely. And I say that as someone whose entire job is finding the cheaper option.

Substitutes work fine when the spec doesn't matter—cosmetic covers, non-pressurized fittings, decorative hardware. They stop working the moment pressure ratings, certifications, or end-connection tolerances are involved.

My rule: if the part is on the pressure boundary, requires inspection sign-off, or touches a warranty claim, buy the spec'd part. If it's downstream of all three, substitute freely and pocket the difference.

That's not a hard rule. It's just been true often enough that I stopped testing it.
