Product Description

This Kerick MA052 float valve is a tank-mount style with an adjustable arm, and is made of PVC with 18-8 stainless steel hardware. The valve has a 0.093" orifice and its estimated rate of flow is 1.3 gallons per minute (gpm) at 40 pounds per square inch (psi) and 1.5 gpm at 60 psi. The valve inlet has 1/2" NPT male extended threads with a sealing washer and jam nut for mounting through a tank wall, and the valve outlet is free flowing. The valve is made of National Sanitation Foundation (NSF) approved PVC (polyvinyl chloride), its replaceable seals are made of TPE (thermoplastic elastomer) for durability and chemical resistance, and its hardware is made of 18-8 stainless steel for corrosion resistance. The valve has a 1.5" in diameter and 4" long polyethylene float attached to the adjustable shutoff lever arm. This float valve is suitable for use in a variety of applications, such as fountains and livestock water tanks.

Float valves use a rod and float ball attached to a valve shutoff lever to control flow in or out of a tank. The float ball rises or falls with the level of liquid in the tank, changing the angle of the valve shutoff lever. When the angle of the valve lever changes sufficiently, the valve opens or closes. Float valves are rated according to the volume of liquid that can flow through them at a particular pressure to ensure the tank can be refilled as quickly as it is emptied. The material that a float valve is constructed from must be suitable for the liquid in which it operates, which may be corrosive or at an extreme temperature. Float valves are used to automatically regulate the level of liquid within tanks in a variety of applications, such as fountains, livestock water tanks, cooling towers, and chemical manufacturing plants.

Kerick Valve manufactures fluid level control valves for industrial applications. The company, founded in 1994, is headquartered in Jacksonville, FL.

If you need to install a float valve inside of a typical 5 gallon bucket, e.g. to create a pressure reducer, then this is the valve you need.
Comes with a nut and washer, which should suffice; I used a 1/2" bulkhead fitting from the hardware store.

This, installed in a 5 gallon bucket with the appropriate accessory plumbing, will serve as an "always full" supply for a gravity fed poultry "nipple" style watering system.

This thing is much smaller than I had pictured in my mind. The whole assembly is barely longer than my open hand, so it can fit into tight spaces for a fountain project, or in a sump to maintain water level in a swimming pool. The description here at Amazon.com is nonsense, giving its length as 1 inch: The actual overall length is about 7.5 inches, or 6.5 inches from the mounting flange to the tip of the float, worst case. (See the second vendor-supplied image with the valve photographed against an inch grid for a better understanding of its actual size.) With allowance for installation and adjustment, the valve could be squeezed into a space as small as 8 inches by 2 inches. If installed in a bulkhead, the mounting surface should be flat and no thicker than about 0.25 inch, to allow enough thread protrusion on the outside to attach a threaded pipe fitting. Bulkhead mounting is optional: The male pipe thread on the valve is slightly tapered and can be screwed into any female pipe thread fitting, using Teflon tape on the threads for a watertight seal

I gauged the valve orifice with a drill rod at 0.094 inch (3/32 inch) diameter, which accounts for the low flow rate specification. You may not want to fill a swimming pool with it from scratch, but for a typical backyard pool it will allow more than enough water to flow to compensate for evaporation loss. The float arm pivots on a stainless steel cotter pin, so it could easily be disassembled, should the need arise, although at the low cost of the assembly it may be more economical to replace it entirely. Depending on the placement of the valve, the float can be adjusted over a liquid level range of at least 4 inches, possibly as much as 6 inches, by loosening the stainless steel wing nut.

I used this to make an automatic water dish for the dogs. It is easy to set the level and has positive water shut off when the float gets to the pre-determined level you set. Now the dogs never run out of water and its always fresh. I purchased two so I would have a spare, haven't needed it yet. Get a low profile plastic container 4-5 inches tall, cut proper size hole on side near top, install float valve and hook up to hose, presto unlimited water supply for animals! Some auto-watering dishes are $25 or more.

I originally got a 1/2" MNPT float valve. I then bought 2 more 1/4" barbed valves and attached vinyl tubing to it. I am using these to connect my garden gutters for my plants. Problem with the vinyl, even though I covered the tubing with mulch, the tubing swells up from the water pressure and sun heat almost to the bursting point.
So I scraped the tubing and ran PEX tubing with crimp end fittings. Much better now! I did have to use a small piece of vinyl to slip over the barbed valves to match up with the inside diameter of the PEX, and then crimp the connections with stainless steel crimp connecters.
Bottom line - Buy the 1/2" MNPT valves and go to Home Depot or here and buy 1/2"FNPT x barb swivel quick connecters, either elbow or straight. The quick disconnect swivel x barb adapters make disconnecting and reconnecting able to be done only using your fingers. Nice when you need to winterize your garden! Several people make the swivel adapters - Watts and Shark Bite. Both are in the plumbing section of home depot or here on Amazon.

This has got to be the best purchase I have ever made for my pool. I used to worry all the time about the water level going below the skimmers and potentially damaging my pump. Additionally, it would take a few hours to fill the pool up to a good level so I would have to wait around and hope I didn't forget to turn off the water before going to sleep.

This float valve has eliminated all of that. With a quick trip to home depot to get some PVC fittings, I was able to hook it up to a garden hose to create an automatic pool filler that is set it and forget it. I was worried that my large pool (36,000 gallons) might be too much for the valve to keep up with in the middle of summer, but it works perfectly. This would be my first recommendation for anyone with a pool.
