1" Universal Hudson Valve - Gravity/Pressurized Flow

QC Supply Part #: 120016
Shipping: Standard
Availability: In stock

The Hudson Valve is a damage-proof automatic valve for fluid control.


The Hudson Valve is a Damage-Proof Automatic Valve Used for Fluid Control.

This 1" Universal Hudson Valve was redesigned with a new float, filter and insert to be more versatile nad longer lasting. The new materials allow the valve to work in water temperatures up to 175° F.

The Hudson Valve maintains fluid levels in various applications, replacing ball float valves. The Hudson Valve's internal parts are made of ABS plastic, EPDM rubber & stainless steel. Fluid levels force a float to rise and close the diaphragm chamber as the diaphragm expands to stop the incoming flow. When the fluid level drops, the diaphragm escape is opened and allows the fluid to fill the tank. The Hudson Valve is resistant to freezing.

We also carry the Benson Bracket (#120032) for easy mounting of the Hudson Valve to tanks and troughs (works only with the 1" valve), as well as the Hudson Valve Repair Kit (#120019).

Additional Benefits:

  • No lever arm
  • No exterior moving parts
  • Installs in seconds
  • Rust-proof
  • Fills FAST
  • Indestructible
  • No float ball or lever arm
  • Freezing won't damage it

    Great item

    Review by on Feb 14, 2017

    Item works just as discribed, very satisfied. Now I don't need to worry about overfilling my water tank. Items was 1/4 the price of other items.

    Valve works great. Mounting bracket is weak. I've "homemade" brackets that work much better.

    Best control valve ever

    Review by on Jul 26, 2016

    Wasn't sure when I first saw the valve how good it would work but was pleasantly suprised to find it the best I have ever used ! Mostly trouble free ! Plan to use more at other locations on my farm !

    Great water fill valve

    Review by on Jul 8, 2016

    After many years of frustration using a float valve to control the water level in my water feature, I decided to try the Hudson fill valve and Benson bracket. Very very happy! The valve controls the level within 1" and shuts off perfectly. I mounted the bracket to a thick piece of flagstone standing on it's side near the edge of the lower pond. Install took less than 15 minutes and most of that was adjusting my piece of flagstone to the right level. I would definitely recommend this product...

    Good Product / Minor Issues

    Review by on Dec 29, 2015

    The diaphragm action of this product is much more reliable than ordinary float controlled valves. It should last much longer and with fewer problems. And generally that has been my experience with some minor exceptions.
    1. It needs a much finer debris screen to prevent small particles from the water supply from entering the diaphragm area. If one gets through, it can prevent the diaphragm from closing. The amount of water that can flow through this 1" valve before you catch the problem can be a few thousand gallons.
    2. Hudson offers a 'high temp" valve control. It's a very small button that controls the opening and closing of the diaphragm. If you connect the valve to a garden hose, install these high temp buttons. In the summer the water in the hose will heat up between valve openings and this hot water will prematurely fail the standard button. The high temp button are only $.50 each. You can order them direct from Hudson on-line.

    This unit does the trick!!!

    Review by on Jun 25, 2015

    This unit does the trick. Easy to install, reliable, and it has solved a problem that I have had repeatedly in the past that was very expensive to fix - needing contract labor, etc. Now I just fix it myself and don't have to worry about it. So glad that I found this product.

    Good water float

    Review by on Apr 12, 2015

    The only complaint I have with this water float is I have not been able to get them to last more than a year. For some reason they don't winter well when not in use. Other than that we really like them.

    Good Product, Great Price and Delivery

    Review by on Jan 5, 2015

    I have used this product in an application where its high flow rate was a necessity. Most valves don't have a good flow rate. This one does. But that's a good news/bad news thing. If it hangs open (which my second one did two weeks after installation) you can waste a lot of water (probably 2500 gallons in my case). Hudson literature says this is caused by small particles of debris that keep the diaphragm from operating properly. They should put a screen on the inlet with fine enough mesh to prevent those particles from entering the valve.

    This is a very good float valve.

    Review by on Dec 27, 2014

    This is a very good float valve. You do need to make sure that you have a pressure reducer otherwise it won't last very long.

    Best in its Class

    Review by on Oct 23, 2014

    Used this for years for 100 - 600 gallon tanks for horse and cattle - larger tanks get two valves. Not perfect, but it is easy to repair, hard to get broken by live stock, and resistant to freezing. We typically use galvanized pipe to mount for the rigidity. Do make a point of mounting it securely to the tank. Use of through bolts with rubber washers will extend the reliability.

    Prompt service. Works fine

    Review by on Sep 17, 2014

    I needed a valve to keep my garden pool at the proper level. A cheaper one was very flimsy so I returned it and got the Hudson. I have another Hudson in another pool and I has worked perfectly for 8 years.

    Review by on Jun 13, 2014

    The valve was purchased on the strength of the recommendation by Michael Kreisle from a Utube video. It is exactly as depicted and will be suitable to our application for a tank to supply our pressure washer. The valve arrived 10 days after the order which is great seeing we are in Australia. Great service and price.

    keep your eye on them

    Review by on Apr 23, 2014

    I have used these valves for about 8 years, on my 3rd one. They work great but you have to keep your eye on them to catch them failing, after about a year or so. The result was a kill of all my koi in a 2500 gal pond due to the chlorinated water going in. I still use them but you have to keep your eye on them.

    Fixed a fish pond

    Review by on Mar 17, 2014

    I have installed this valve on a 700 gallon fish pond that has a history of leaks associated with the small waterfall. I was able to attach to a 1 inch irrigation line 10 feet from the edge of the pond. Now I can leave the waterfall and its incorporated biologic filter operating when I travel. Previously I had to pull a hose and periodically add large amounts of water at one time. This valve will allow unattended more frequent smaller additions.

    1 inch Hudson valve

    Review by on Jan 13, 2014

    Have used 10 0f these and until now, all have been very satisfactory. The one previous to new purchase leaked water (did not shut off.) Not sure why. Replacement seems to be working fine. History is valve needs replacing once a year which seems to be related to hard water building calcium.

    Best Valve for my purpose.

    Review by on Nov 20, 2013

    I had several different float valves for my ponds. They weren't as compact and didn't last. This valve fits perfectly with my plumbing design. I had to replace this valve after 4 years.I thought I needed to clean it, and after taking it apart to do so, I couldn't get it to shut off. I couldn't figure out why it wouldn't work anymore, so I bought a new one.

    Plastic pin problem solved by Hudson

    Review by on Jul 18, 2013

    This valve is used to shut off the supply to a 1000 gallon well water reservoir tank. The original worked for about 7 years. Inexpensive and easy to replace. The plastic pin problems mentioned in earlier reviews appears to have been solved by Hudson. It is now a sheet metal type screw so it is easy to remove and replace without damage.

    Review by on Jun 3, 2013

    Couldn't get the valve to shut off, even after allowing the control chamber to fill up with water. Had read previous posts about similar problem. Took it apart and re-tried twice before it would shut the water off. Never did decide just what the problem was. Now it seems to work fine. Using it to maintain water levels in two 1500 gallon holding tanks.

    Review by on Oct 8, 2012

    Good product for the automatic pool fill. Only problem is the small rubber washer at the top of the shut off which deteriorates and it is not available in the parts kit so you end up each time having to buy a whole new valve. QC's prices though are substantially below all the competition.

    Best answer to a koy pond with plants and fish

    Review by on Sep 19, 2012

    I ordered this valve to replace one I had been using for several years. The old one had limed up over years of uneventful use. While waiting for the new one, I simply took the old one apart and cleaned it with "lime-away". Wow, easy to take apart, clean and replace. Now I have a standby for next time.

    If you have a pond with plants, fish and other items, this is the answer. I tried other types with which did not meet my requirements.

    Pin problem fixed!

    Review by on Aug 22, 2012

    The old plastic pin was hard to remove, and I was happy to see the new valve has a regular metal screw in place of the plastic wedge.

    My only complaint with the valve is it can emit an annoying hum or buzz when it is at the full state. But this was caused by a mounting that was not rigid enough with about 7 inches of free lead in plastic pipe providing a nice spring for resonance. Fixed by adding a rubber damper.

    Ought to throw in an extra pin

    Review by on May 4, 2011

    My plastic pin (p/n P10) broke too. I improvised with a plastic zip tie but it isn't as good. And I don't see that P10 pin part for sale here. I disassembled the valve thinking it needed cleaning when it didn't (my problem was upstream of the valve).

    Aside from that one pin issue I have had two of these operating flawlessly for 5 years continuously. These are the closest things to a "solid state" no-maintenance float valve I have ever found. For less than $25 a pop get two for goodness sakes.

    Good Valve, poor pin design.

    Review by on Apr 3, 2011

    When I went to remove the plastic pin that holds the float valve in place it broke in two. The pin is clearly not well designed or strong enough.
