It sure can. Schedule 40 and 80 have the same nominal size fittings and will fit together.
We typically will use slip and glue it in place and add 2 unions before and after the valve to make changes, movement and working with the valve easier. If you thread in the valve it still can't be removed easily as it will be threaded in opposite directions from either end and make removing it a bit of a process where as Unions will simplify the process. Feel free to let us know if you have any further questions!
All plumbing and fittings on our website are sized based on the nominal pvc pipe rating (meaning the internal diameter of the pipe). This means that a 1.5" bulkhead or coupling or union will accept 1.5" ID/nominal pvc pipe.
Hope this helps!
The golden rule of plumbing is that every job takes three trips to the store. While this can be frustrating locally it can be much worse when shopping online. Being short a fitting or two can delay a plumbing project for days. Here are some quick tips to avoid this.
- Plan your plumbing on paper
- Don't skimp on unions. Unions allow for easy breakdown and maintenance as well as remove the need for precise elbow placement. Use them as often as possible.
- When in doubt order extra. We happily accept returns for a full refund (less shipping) on all unused fittings within one month of purchase. A few extra bucks in return shipping is less frustrating than a project delay.
Very nice valve By Willie on 5/31/2017Willie would recommend this product to a friendReceved the 1" slip x slip and installed it on my Herbie drain pipe, I havent tested it yet but im sure the operation of this valve will be very smooth while trying to adjust the full siphon drain! More reviews to come after it gets wet!
Great on the Bean Animal By James on 5/29/2017James would recommend this product to a friendI have this under a Synergy Reef Shadow Overflow and it works great. set and forget!
Great Valve By David on 4/27/2017David would recommend this product to a friendI bought this to replace a ball valve, the crap you buy at Home Depot. Amazing product! I can't begin to describe how perfect this works. I would normally spend hours trying to get the water level perfect in my overflow with a traditional ball valve. Took me just minutes with this gate valve. Extremely easy to turn and well made!
save yourself the hassle of sticky ball valves! By Nick on 3/29/2017Nick would recommend this product to a friendat first i was in total sticker shock when i seen the price of these, needed 3 for my build and almost passed em up... SO GLAD i didnt. so much so, i convinced my buddy to get the same ones for his build. don't skimp on this piece or unions.
Excellent for fine control By Chris on 5/17/2016Chris would recommend this product to a friendI use two of these. one to tune my Herbie overflow and the other to tune flow through my fuge. Very well built
Excellent fine-tuning but needs constant adjustment By Jazmyne on 5/31/2015Jazmyne would recommend this product to a friendI used the spears 1" gate valve to replace the ball valve I originally installed on the siphon to my sump. I've had it on my tank for nearly six weeks. While it's much easier to dial in than the ball valve, I find I have to adjust it every other day or so to keep the water in the overflow at the right level.
For the price, I would expect it to hold its setting better.
High Quality Parts By Kyle on 5/1/2015Kyle would recommend this product to a friendI opted for the Slip X Slip version of this valve and was not disappointed. Welds very well (made sure to weld while valve was open - didn't want gunk on the gate itself) and you can just tell that it's built to last. Turning action of the valve is very smooth and you can fine tune with these extremely well. My ONLY wish is that they made a True Union version of these rather than me having to put unions on both sides.
High quality product By Michael on 1/7/2015Michael would recommend this product to a friendHaving gone to a few different hardware stores while deciding what to get for my plumbing, I went for this based one great reviews. The reviews were right, well worth spending the extra money to get a high quality product that will last longer and be easier to use long-term. Don't waste your time or money on ball valves!
You Need To Buy This By Evelio on 12/9/2014Evelio would recommend this product to a friendThis valve helped me maintain a precise flow through my sump. I will definitely be purchasing more of these valves in the future.

minute adjustments have literally made my overflows silent.
Great Valve; Worth Every Penny By Brandon on 1/30/2014Brandon would recommend this product to a friendThis is an extremely well made product and I would recommend this to everyone; even if you used sch 40 for everything else, get this.
