Anyone using the Hill regulator/valve/hammer combo?

Postby JohnL57 » Mon Nov 13, 2017 10:49 am

I have a .25 Gen 1 and would like more shots. I ran across the Hill website and got interested in their Regulator/valve/hammer combo.
Almost sounds too good to be true, I'm wondering if there are any users out there with real world feedback. It's not an inexpensive mod, but I'd go for it if it really works that well. The kit does come with an enlarged transfer port.
Thanks,
John

Yes, it is a pretty good setup Hill offers. I don't like the anodized aluminum hammer though for longevity sakes, but I have never owned one either. I have used the Hill valve and gauge port combo along with his 6lb valve spring and the high flow transfer port out of his kit. I used a Rocker1 32 gram MDS hammer instead along with a TSS from Air rifle Technologies and a Huma regulator to complete my mods.

Looking at some of my recorded strings with this Hill valve setup, I was able to get 43 shots using the JSB kings. The ES was 4.0% (35 fps spread) and the average FPE was 40.65 with the Huma set at 1850 psi.

I ran another string with the JSB kings and got a 1.98% ES (17 fps spread) for 35 shots averaging 41.03 FPE with the reg set at 1800 psi. Both of these strings were on a 3200 psi fill.

I have two strings I recorded using the Hill valve and the JSB MKIIs. On the first one I got 22 shots with an ES of 0.98% (8 fps spread) averaging 50.09 FPE on a 3100 psi fill with the reg set on 2000 psi. On the second one I got 25 shots with an ES of 1.11% (9 fps spread) averaging 49.23 FPE on a 3150 psi fill with the reg still set at 2000 psi.

So hopefully I have given enough data to help you see what the Hill valve can do. If it were me though, I would want to wait for the new SS valve that is about to be released from Air Rifle Technologies. I am one of the lucky ones that was able to buy one of the prototypes to test out and keep. It is a balanced valve which requires much less hammer energy than the typical spring valves do for stock like cocking ease even with higher power tunes.

To compare the two valves, my current tune using the MKIIs with the new SS valve is giving me 24 shots averaging 55.92 FPE with a 2.08% ES (18 fps spread). I did another tune with the MKIIs which gave me 34 shots averaging 49.83 FPE within a 1.47% ES (12 fps spread). Both were on a 3200 psi fill.

The biggest difference besides the much better efficiency with the new SS valve is the easier cocking and less hammer spring needed. I use to use two hammer springs together with the Hill valve and now I just use one lighter spring even with more FPE. My gun is much quieter when shooting with the SS valve.

It is up to you which way you want to go, both are better than a stock setup. The SS balanced valve should be coming out fairly soon so you just have to keep checking the A.R.T. web site store.

Hi, I just put the full kit in an Armada. It looks like good quality parts, however I' stil trying to get the tune right. The strings I have fired so far aren't living up to the reviews on his web page and like all the air gun gurus he don't ansewer his email. There don't appear to be much to tune. I'll post the few strings I have shot so far.

Yes, those strings can be much better. What are your port sizes? It looks like you are using too much hammer spring/hammer energy and I suspect you do not have enough airflow from the valve to the pellet skirt and are cranking in the hammer spring too much to reach your ~850 fps goal. You are using way too much air per shot so a lot of air is getting wasted per shot. How are you addressing hammer bounce? Make sure the TP seals are good and sealing and the breech O-ring is in place and good. What hammer spring are you using?

Well I can't speak for any of the ports other than the barrel transfer port it was drilled with the bit which was included with the complete kit 184". The transfer port tube looked to be about the same size maybe a little larger buy a few thousands. It was a white piece of tubing that slipped down the TP into the Hill valve, there are no seals, and then up into the receiver/barrel port it was tite and felt like a good seal. Don't know anything about the spring it came with the kit. The valve is Hill's valve the blue one. The Hammer spring is in 2.5 turns of rom startper the Hill instructions.mthe regulator, is set at 21/2200 psi gage reading. The Hammer is the Hill hammer and hill lubed. With the valve striker fully counter clockwise. Yes the breach O-ring is in place and looks new, this is a brand new Armada. It only had about 10, 8 shot strings shot through it for reference. Don't what else to tell you.
Merry Christmas
