Overview

The AVG NRI-PRV-15C 15mm 1/2" Non-Return Isolation & Pressure Reducing Combo Valve combines 2 valves in one as a compact unit to save cost/installation time and eliminates a potential leaking point. This AVG NRI-PRV-15C combo valve is commonly supplied as part of AVG Quickie kits and many solar hot water installation kits, making the NRI-PRV-15C a popular direct swap item during the pressure valve train servicing without changing the plumbing layouts. 

The AVG NRI-PRV-15C combo valve is directional marked by the arrow on the valve body. The blue handle is part of the non-return isolation duo valve assembly and can turn the water supply on/off. The brass barrel houses the adjustable spring, which can be turned with a screw driver and allows pressure adjustments between 250-650kPa with a factory preset at 500kPa. Therefore, it is best to have this brass barrel facing up (the blue handle facing down) during installation to allow easy access to adjustment screw, despite all AVG marketing materials/photos show the valve upside down. 

The AVG NRI-PRV-15C combo valve is Watermark approved and features 15mm 1/2" copper olive compression fitting ends for direct copper pipe connection or used as a male thread with the cone nuts removed. A pair of insulation jacket is included to minimize the heat loss.

Please note, this the newer and updated version of AVG NRI-PRV-15C combo and it no longer has a 6mm pressure test point to insert a pressure gauge. This new unit superseded the old version in 2022. A photo of the old version AVG Combo valve is shown at the end of the photo gallery for the reference.

Unless you're buying it for a child, I'd pass on this one.
Color: Black (Bifold)
Gotta say I'm pretty disappointed with this item. It's literally just 2 pieces of leather sewn together. Very flimsy, and all edges are raw/unfinished. The reason it's still getting a couple star rating is because it is a good size for a standard wallet, and it would be comfortable as it is so floppy, but you could probably expect to end up with bent or broken credit cards because of that. Overall I'd say your just paying for the name on this one and I'd pass unless you can get it for super cheap, for there's no way this thing is going to last the test of time.

not impressed
Color: Brown (Bifold), Color: Brown (Bifold)
I own several articles of Carhartt clothing, most of which i got from a thrift store; it has been said that Carhartt meant quality--and quality meant high prices. When a Carhartt item became available through the Vine program, I was surprised, and decided that I would use this opportunity to pick up what I thought was going to be a good quality wallet. Nope. For what they ask for their stuff, you would assume that it was made with high quality materials and in the united states. this wallet misses the mark on both of those points. it is clearly stated on both the packaging and inside the wallet itself that it is made in india. the leather is thin and and may be so to effect the rapid aging and forming of the wallet around its contents, but it only has 3 card slots and a mesh-windowed ID card slot, so that seems like a stretch of an excuse. More likely, Carhartt cheaped out on materials. the stitching looks like it is made with plasticky thread , which may not hold up very long. but it IS embossed with the Carhartt logo, which is all some people need.

Rustic sturdy & simple leather wallet
Color: Brown (Bifold), Color: Brown (Bifold)
This Mens Full Grain Patina Leather Wallet has a rough, durable and rustic style with basic functionality and capacity as well as slim profile as in my pictures. I put about 10 dollar bills and a couple of my cards in this bifold wallet in my pictures. (You can put 3 cards in the card pockets on the right and 1 in the mesh pocket on the left.) It has a hard relatively smooth outer surface and a coarse surface on the other side. Over time of use, I would expect the leather to become tenderer. If you are looking for an affordable slim leather wallet with minimum functionality and capacity, this will be a good candidate. Thank you for letting me review this product.

Simple, Rugged Wallet with Classic Carhartt Style
Color: Black (Bifold), Color: Black (Bifold)
I ordered this Carhartt Patina Leather Bifold wallet and it is exactly what you would expect from the brand. It is simple, sturdy, and practical. The wallet comes packaged in a nice Carhartt box, which makes it feel like a quality item right out of the package and would make it easy to give as a gift. The leather has a smooth finish on the outside with clean stitching around the edges. It feels durable and like it will hold up well with everyday use. The interior has a more rugged, suede-like leather texture which gives it that classic workwear look Carhartt is known for. Inside there are three card pockets, a billfold pocket, and a clear ID window which makes it easy to access identification quickly. The layout is simple but functional and it keeps the wallet fairly slim so it should fit comfortably in a front or back pocket. Overall, this is a well made everyday wallet with a classic look. If you like Carhartt products and want something durable without a lot of extra bulk, this wallet is a solid option.

Compared to g-shock?
Color: Black/Yellow
Firstly random public reviews can be comical…”it’s has a battery, terrible, One star” or “I don’t like yellow, one star” omg peoples do better. I’ll review this while comparing to an older style of g-shock from the same era. I’ll start by saying this timex rocks, for me in my mid 50’s it’s so retro and nastalgic, brings back memories, I may have even owned this model back in the day. What’s great about it- the display, larger digits than the typical g-shock and they are super crisp, clear and easy to read. The indiglo is awesome. This is the most accurate quartz watch I have aside from the atomic g-shocks that adjust themselves daily. I prefer a chunky watch and the g-shocks do a better job in that department. i feel this watch is rugged, but I’d still give the nod to g-shock in this department. 200M water resistance is the gold standard and this watch has it which I love for peace of mind for any water based activities. This is a 5 star watch at a great price. I still love some aspects of a g-shock better but its just preference.
