Questa valvola a galleggiante Kerick MA052 è di tipo montato su serbatoio con un braccio regolabile ed è realizzata in PVC con hardware in acciaio inossidabile 18-8. La valvola ha un orifizio di 0,093 e la sua velocità di flusso stimata è di 1,3 galloni al minuto (gpm) a 40 libbre per pollice quadrato (psi) e 1,5 gpm a 60 psi. L'ingresso della valvola ha filettature estese maschio da 1/2 NPT con una rondella di tenuta e un controdado per il montaggio attraverso una parete del serbatoio e l'uscita della valvola è a flusso libero. La valvola è realizzata in PVC (cloruro di polivinile) approvato dalla National Sanitation Foundation (NSF), le sue guarnizioni sostituibili sono realizzate in TPE (elastomero termoplastico) per una maggiore durata e resistenza chimica e il suo hardware è realizzato in acciaio inossidabile 18-8 per la resistenza alla corrosione. La valvola ha un galleggiante in polietilene di 1,5 di diametro e 4 di lunghezza fissato al braccio della leva di intercettazione regolabile. Questa valvola a galleggiante è adatta per l'uso in una varietà di applicazioni, come fontane e serbatoi d'acqua per bestiame. Le valvole a galleggiante utilizzano un'asta e una sfera galleggiante attaccate a una leva di intercettazione della valvola per controllare il flusso in entrata o in uscita da un serbatoio. La sfera galleggiante sale o scende con il livello del liquido nel serbatoio, modificando l'angolo della leva di intercettazione della valvola. Quando l'angolo della leva della valvola cambia sufficientemente, la valvola si apre o si chiude. Le valvole a galleggiante sono classificate in base al volume di liquido che può fluire attraverso di esse a una particolare pressione per garantire che il serbatoio possa essere riempito con la stessa rapidità con cui viene svuotato. Il materiale con cui è costruita una valvola a galleggiante deve essere adatto al liquido in cui opera, che può essere corrosivo oa temperature estreme. Le valvole a galleggiante vengono utilizzate per regolare automaticamente il livello del liquido all'interno dei serbatoi in una varietà di applicazioni, come fontane, serbatoi di acqua per bestiame, torri di raffreddamento e impianti di produzione chimica. Kerick Valve produce valvole di controllo del livello del fluido per applicazioni industriali. L'azienda, fondata nel 1994, ha sede a Jacksonville, Florida. COSA C'È NELLA CONFEZIONE? * Valvola MA052 * Sfera galleggiante PF154

Ingresso filettato maschio 1/2 NPT e uscita a flusso libero. Nota: MA052 ha una filettatura del tubo da 1/2 NPT. Questo è estremamente comune nel mondo idraulico. La filettatura misura circa 3/4 di pollice di diametro, questo è un errore comune a coloro che non hanno familiarità con le filettature dei tubi e l'impianto idraulico. Montaggio su serbatoio con filettature estese sul lato di ingresso della valvola per il montaggio attraverso la parete del serbatoio. PVC per resistenza alla corrosione. Portata stimata fino a 1,5 gpm a 60 psi.

Works - but for how long
This is the second one I bought. They last for about 6 months. Then they get stuck in the closed position. Going a different route next time.

Size misleading
Too small

Excellent value
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. One of these valves was successfully used to maintain the water level in a neighbor's swimming pool last summer during a month-long absence. See the customer photo that I posted, showing the minimalist installation with a few pieces of PVC plastic plumbing, an ordinary brick and a garden hose. The only problem I encountered was the hose of the automatic pool sweep once getting hung up on the valve, keeping it open continuously. Because of the restricted flow, no flooding occurred by the time I discovered the problem the next day. If I use it next summer again, I'll mount the valve with some sort of bumper or "fence" around it to keep the pool sweep hose clear, and I'll replace the leaky plastic hose fitting with a sturdier brass fitting.

Works as Intended
This was easy to install and I use it in a backyard water feature. It has a 1/2" intake and seals well when full.

Good valve when working, but 4 of them have failed after about 6 months.
The valves last welll for months, but then the seal, a 1/4" white plastic, nail-shaped part, is prone to internal bubbles full of water, which make the valves suddenly begin to leak badly, wasting water. The seals are difficult to replace down in our swimming pool filler sump, so I replace the whole valve. ...but proper molding by the manufacturer would have been much better. They the seals appear to have been molded with air bubbles, which eventually fill with water under pressure, so the seal grows a flexible lump. ...which you can break with a pin, and water comes out. I would replace with different brand, but all these small valves seem to have the same form. ...appear to be made, maybe, by the same maker.

Worked Perfectly in Fountain Setup. Excellent Sizing Guidance on Product Page
Bought as a replacement valve. As a non-plumber, I greatly appreciated the product description and picture showing the actual size for the item (the thread is about 3/4", but matches the 1/2" NPT standard). Once installed, this new valve immediately stopped the leak that I had with the original valve.

Reliable and cheap.
My supply pipe coming out of the pool, flush on the wall tiles is 1/2". So I buy a 1/2" barb fitting male NPT, 70 cents lowe's. Soften the barb fitting on a trial scrap 1/2" pipe to reduce the barb diameter, or you can sand the barb with drill chuck to the id of barb fitting, around .010 bigger over the 1/2" pipe ID. (Do Not Drill the pool pipe ID to make it bigger, you need a smooth weld when you apply a primer and glue on pipe for water pressure application integrity, wait about 2 hrs. Connect a 1/2" elbow then the kerick valve, so the whole unit is parallel to the wall of the pool for less obstruction. I have it installed for about a 2 weeks now, set about halfway or middle of the mouth of the skimmer, with stable height the whole two weeks. Usually my pool go down 1/2" every 2 days, then I fill it up, about 30-45 minutes with timer, until the middle of mouth of skimmer. The water ball valve on the faucet is set on the low opening to avoid overfill just in case this kerrick valve malfunction. The thread on this is not a standard 1/2" NPT, but that 2 turn is enough, with the help of a provided nut, no leak, so no problem for me.

Does what I wanted it to do.
I wanted a water holding tank and used a 20 gallon Husky Garbage can, mounted this on it and it works just fine. I use the water with a very weak solution of fertilizer to water my 80 plus orchids and other plants. I had to use a couple of sturdy plastic plates to solidify the installation because the weight of the hose would buckle the area where it's mounted. But once that was done, it works just fine. October 28th, 2015 addendum: I think that something like this would also work great for adding water to an aquarium or fish tank. If the water coming out of your tap is chlorinated, letting it sit for a while will help dissipate the chlorine. This could also work as an emergency self filling water tank. Here in Hawaii, we are constantly warned about the possibility of a hurricane. A 33 gallon CLEAN garbage can filled with water would certainly help in an emergency. Just leave the cover on to keep dust and debris from getting into it. Actually, if you think hard enough, there are a lot of possibilities with this.
