Brand:Valterra

3.5/5

Questa valvola a saracinesca ha applicazioni a bassa pressione e vuoto in magazzini climaticamente controllati, capannoni per maiali/pollame, stagni di liquami, stagni di acquacoltura/koi e chiusura di linee fognarie e controllo delle acque reflue, nonché molte applicazioni generali. Si prega di notare che ogni dimensione della valvola ha un rating di pressione aperta e chiusa. Poiché la paletta in acciaio inossidabile può flettersi con l'acqua corrente, non è adatta per strozzare l'acqua o tentare di chiudere la valvola con acqua in rapido movimento, quindi il flusso medio basso interrompe la pressione dell'acqua di 7 libbre per pollice quadrato (psi). Queste valvole a saracinesca sono talvolta denominate valvole a saracinesca "a coltello o a ghigliottina" e rappresentano un'ottima alternativa alle valvole a sfera nelle applicazioni a bassa pressione poiché sono a flusso pieno, ad apertura rapida e generalmente hanno un costo molto inferiore. Funzionano bene con detriti morbidi come i rifiuti, ma piccoli detriti duri possono depositarsi sul fondo della sede/fessura della valvola e impedirne la chiusura completa. Possono essere facilmente riparati svitando e sostituendo le guarnizioni della saracinesca o il corpo valvola. La maniglia in metallo si svita semplicemente per una facile sostituzione - se lo fai, assicurati di non danneggiare l'albero della valvola. La valvola a saracinesca Valterra 6401 ha 4 raccordi femmina Slip/hub Schedule 40 che ricevono 4 tubi. Il corpo in cloruro di polivinile (PVC) bianco e i raccordi del mozzo sono resistenti alla corrosione e agli agenti chimici delicati, così come le guarnizioni in vulcanizzato termoplastico (TPV). L'albero e la paletta sono realizzati in acciaio inossidabile 304 e il manico è in alluminio. L'hardware è in acciaio zincato. Ha una pressione nominale massima in posizione aperta di 15 psi e 15 psi in posizione chiusa, una pressione nominale massima di interruzione a metà flusso di 7 psi e una temperatura nominale massima di 167 gradi F (75 gradi C). Vedere la tabella di misurazione della valvola a saracinesca per le dimensioni e la tabella della pressione di testa per determinare la pressione in base all'altezza dell'acqua trattenuta.

RIPARAZIONI: Il gruppo imbullonato consente la sostituzione del corpo valvola e delle guarnizioni della saracinesca - La maniglia si svita semplicemente. SPECIFICHE: Pressione massima - 15 psi aperto/15 psi chiuso, Schedule 40 PVC con raccordi femmina Slip/Hub. CARATTERISTICHE PRINCIPALI: Albero e paletta in acciaio inossidabile 304 - Maniglia in alluminio - Flusso illimitato - Apertura completa della porta - Semplice operazione push/pull. APPLICAZIONI: Ideale per applicazioni a bassa pressione e vuoto come chiusura rapida - Può essere utilizzato con aria o acque pulite/grigie/di scarico.

They're ok, but...
These worked great initially but after using for a while, we're having issues. We're using 6 of these on ponds for about 9 months now. 5 work as they should, the other started leaking after use. The screws are stainless, which I appreciate since these are used for water application and some are in a very damp vault box. Will eventually replace with ball valves as they fail. Had I known how frequently we'd be having to use these and how easily they get crud under the gasket or kink the gasket, I would have gone with ball valves. If for infrequent use, they'd be great.

Installed it this afternoon after two day shipping. Very impressed with the quality of the valve, much cheaper than a four inch ball valve. Could not find one locally. This valve is rated only for low pressure, which was my application. Stem, gate and bolts are stainless steel, I hope to get years of service out of it.

Great price. Fast shipping. Easy to install. Used on main sewer line for emergency shut off in event check valve fails during sewer back ups.would give 5 stars but I haven't needed to test it yet. Thank God! :-)

My 15 yr old Mainline backwater valve failed last summer so I had it replaced with a new one and installed the 4" gate valve as a backup for emergencies. Trust I'll never have to deal with sewage backup again!

Well made Valve---BUT WAIT....
I bought 2 of these for a DIY pond setup---for the bottom drains. It seemed a little pricey until it arrived----WOW---nice looking product. The SS slide functions really nice--and it's heavy duty. I was initially very pleased, and installed it in the bottom of a custom pump house 4 feet below grade. The first year everything was fine, but now they both leak terribly and it is a challenge to work on the pump or any plumbing because you CAN'T shut off the water from the pond. The housing does not leak, but the valves are incompetant, and when fully closed, they still let a large amount of water through. Granted, it is much less flow than full bore, but you must wear boots and get prepared to get wet. When I installed the valves, unfortunately I did not leave extra length on the pipes, so I can't replace these valves. I would have to drain the pond to attempt that anyway. I remember that the SS slide had a plastic edge around the slide, so I'm guessing this edge came off, corroded or was eaten by snails, who knows.... So this year, I have replumbed part of this pump house, and I have room to install another valve downstream before my pump --- but I'm going to use another brand. If I need to work on my pump, I want the water OFF.... Sorry guys, your valves failed----- :>(

So very happy with the product as well as the price
It was exactly what we were looking for. We called local stores. It was hard to find and when we did they quoted us $400.00 plus, which is ridiculous. Very happy with the product as well as the price.

Completely dissatisfied!!
Opened box to find item broken and not functional! The item was packaged well, and the broken pieces were not in the box! So this item was shipped broken before it was packaged and shipped!! Very dissatisfied!!!!!

Does the job, a little more bulky when extended than expected.
Still awaiting the flood water to recede for installation to take place - no sure I can use it easily, but I will make it work. It is for isolating the house from drains.

Great valve for French drains
I used this valve to prevent backup during the season of flood water in the river coming back to my French drains. It really seems to be able to do the job.
