I manage purchasing for a 40-person mechanical contractor. Six years ago I took over our pipe and valve budget—about $180,000 a year when you count fittings, pressure gauges, and freight. I've negotiated with dozens of distributors and tracked nearly every order in our cost tracking system. I'm not an engineer, so I don't pretend to select valves by Cv curves or stress ratings. What I do is compare total cost, and that's where most buying mistakes happen.
The comparison I keep coming back to is Apollo Valves press brass ball valve inline model 77VLF versus a threaded Apollo brass ball valve of the same size. Both are Apollo. Both do the same basic job. The difference is in how they get installed—and how much the project actually costs once labor, tooling, and callbacks show up.
What I compare before I compare price
For the work we do, 1/2-inch through 1-inch brass ball valves in potable water and hydronic systems, the 77VLF is a press-type valve. The press ends connect to copper or compatible press tube with a calibrated tool. The threaded version uses NPT threads, thread sealant, and careful installation. The LF in 77VLF means lead-free, which is not optional for potable water.
Before I ask for a quote, I set up three buckets:
- Material cost. The valve price plus adapters and any tooling that has to be bought or rented.
- Installation cost. Prep time, assembly time, testing time, and the cost if a joint fails.
- Lifecycle cost. How easy it is to repair or replace this valve in the future.
If you only compare the first bucket, you are not comparing valves. You are comparing stickers.
Material cost: where hidden fees usually hide
On the surface, a threaded ball valve almost always costs less per unit than the press 77VLF. That is normal. Press fittings use more mating surface and require exact manufacturing, so the upfront number is higher.
But the upfront number isn't trustworthy if the quote leaves out the connection costs. A press valve needs a compatible press tool and jaw set. Contractors who own the tool spread that cost across jobs. If you don't own it, that rental or purchase needs to be counted.
I got burned on this a few years ago. A supplier gave me a quote that looked about 18 percent lower than our local distributor. It didn't include freight or a handling fee, and the tool rental was on a separate line. When I added the final invoice totals, the quote was about 7 percent more than the distributor. I don't blame the supplier for charging those fees. I blame myself for not asking the question I now ask first: What is NOT included?
That is also why I bring up Apollo Valves Conway SC. Traceability matters. A distributor who lists the full model number and can tell me where the product comes from is already showing more transparency than one who just says brass ball valve, 1/2 inch.
Installation cost: the comparison flips
A press connection is fast when everything goes as planned. You deburr, mark the depth, press, and test. After the crew has done a few, a 1/2-inch 77VLF installs in less time than a threaded valve. There's no flame, no hot work permit, and no risk of overtightening.
But that's not the whole story, and it's the part that surprised me. On a small retrofit where the existing line already has threads, a threaded valve can drop in with almost no prep. A press valve may need the old pipe cut back and cleaned before it can be pressed. In that situation, the faster connection is actually slower. A Q2 2024 side-by-side comparison made that clear: press saved time on new multi-valve runs, but lost on single replacements.
So the conclusion is not that press is better or threaded is better. It's scale-dependent.
If you're doing one replacement valve under a sink and don't have a press tool, threaded is often the lower total cost. If you're putting in ten or twenty isolation valves on a new line, press tends to win even with a higher valve price.
Lifecycle cost: the forgotten dimension
Here's the difference that gets overlooked: a threaded valve can usually be unscrewed and replaced without cutting the pipe, assuming there is clearance. A press valve cannot be reused after it's been pressed. If it has to come out, you cut it out and install a new one.
That doesn't mean the press valve is worse. It means the cheapest option over a single install might change when you think about 10-year maintenance. For most projects, the labor savings at installation outweigh the higher removal cost. But for critical valves that may need service, or for locations where cutting the line is a nightmare, a threaded or union-connected valve could be the better play.
Where Conway SC and the 77VLF fit in
Apollo Valves has a U.S. manufacturing footprint that includes its Conway, SC facility. I mention Conway for a practical reason: traceability. When I see the full model number and the supplier can confirm the source, I know I'm not dealing with a substitute or a vague listing.
The same discipline applies outside valves. I once helped someone look over a 40V lawn mower parts list he ordered online. The seller listed parts by generic names instead of real model numbers. Three parts didn't fit, and the repair ended up costing more than the mower was worth. The same thing happens with cabinet hardware. If the invoice doesn't include a finish code, model, and return terms, a small misorder turns into an extra trip. Where to buy cabinet hardware matters less than buying from someone who gives you enough information to order correctly.
Even simple tool questions follow the pattern. People ask what size nut driver for hose clamp. The most common sizes I see are 5/16-inch and 8-millimeter, but not every clamp uses the same hex. If you aren't sure, carry both. That extra tool costs less than an extra trip.
Which one would I choose?
For new commercial installs with more than a handful of valves: Apollo Valves 77VLF press ball valve.
For an accessible one-for-one replacement in an existing threaded line: threaded Apollo ball valve.
For any potable water system where lead-free compliance is required: check the specification and make sure the model includes the LF designation. Don't let a discount substitute make that decision for you.
And when a quote looks lower than expected, ask the supplier to break down every fee before you commit. In my experience, the vendor that lists charges up front—even when the total is higher—is usually the one that costs less at the end.
