Dispositifs de contrôle - CR25-100 - Soupape de surpression en laiton série CR25 CR, plage de pression réglable de 0 à 100 psi, 1/4 mâle NPT

Brand:Control Devices

3.6/5

38.64

Cette soupape de surpression Control Devices CR25-100 a un corps en laiton, une pression de surpression réglable, un raccord d'entrée fileté 1/4 mâle NPT et un joint torique en fluorocarbone. Le corps en laiton de la vanne, le siège de vanne en laiton et le clapet en acier inoxydable résistent à la corrosion et peuvent être utilisés à des températures de fonctionnement allant jusqu'à 250 degrés F. La vanne peut être réglée pour s'ouvrir entre 0 et 100 psi à l'aide du bouton en nylon de style micromètre. Cette soupape de sécurité a un débit standard de 6 pieds cubes par minute (SCFM) et convient aux applications de décompression à faible débit telles que les compresseurs d'air sans réservoir. Les soupapes de décharge éliminent l'excès de pression ou le vide d'un système. Les ouvertures de la vanne permettent aux fluides ou aux gaz de s'échapper pour diminuer la pression, puis se ferment une fois que la vanne atteint la limite de pression de repositionnement. Ils soulagent également l'excès de vide en s'ouvrant pour libérer un gaz dans le système, puis en se fermant après avoir atteint sa limite de basse pression. Certaines soupapes de décharge ont un mécanisme de réglage pour régler la pression à l'endroit où la soupape s'ouvre, ce qui la rend adaptée à diverses applications. Les soupapes de décharge sont évaluées en fonction du volume de liquide ou de gaz qui peut les traverser et le matériau à partir duquel la soupape est construite doit être adapté au fluide ou au gaz, qui peut être corrosif ou à une température extrême, dans lequel elle fonctionne. Les soupapes de décharge sont utilisées dans une variété d'applications, telles que les compresseurs d'air, la fabrication pétrochimique et chimique, le traitement du gaz naturel et la production d'électricité. Control Devices fabrique des soupapes et d'autres dispositifs de contrôle de débit. La société, fondée en 1963, a son siège social à Fenton, MO.

Bouton en nylon de style micromètre pour le réglage de la décompression. Le joint torique en silicone fournit une étanchéité étanche jusqu'à 10 % de la pression de réglage. Construction en laiton et ressort en acier inoxydable pour une résistance à la corrosion. Raccord d'entrée fileté 1/4 mâle NPT. Pression de décharge réglable de 0 à 100 psi.

1 year of use and still good
I bought this to install on my steam sterilizer. The sterilizer reaches 121°C (250°F) and 15-18psi. I obviously have an additional safety release valve and a pressure gauge. The markings on the adjustable valve seem to be within the stated tolerance. It does occasionally get stuck closed. I learned it is best if I open it completely to vent before building pressure and then adjust it when the desired pressure is reached to allow very minimal venting. It never gets stuck if this is done. It always closes and does hold a vacuum upon cooling. All in all it does exactly what I want. I may replace it soon with the same valve simply because it is cheap and for peace of mind. 4/5 for overall quality 5/5 for quality at low price

Good as a PRV
I’m using this PRV as part of a pressure fermentation and spunding rig. For my use it works really well with one exception. It needs to be used with a pressure gauge since the gauge on the pressure adjustment is 10-15 psi off. 10 psi on the PRV is actually 15 psi on a gauge.

it works pretty cool so far for what I use it for
It relieves a fair amount of pressure. I believe more expensive valves relieve more pressure if that is what you need. Overall, it works pretty cool so far for what I use it for. Ignore the numbers used for measuring on this item. It's only there to make the item more attractive to buy. I had to buy a nut for mine in order to install it, which wasn't very hard. I use mine along with a pressure gauge on a homemade low pressure 55 gal steel sterilizing/pasteurizing drum. I never allow the tank to exceed 2 psi. I use this item basically to begin relieving pressure when the pressure reaches 1-1.5 psi. I adjust it according to my pressure gauge. It is most useful to me really in that it is an alarm for me to turn the propane down or open more wide the main relief valve. And I'm sure it helps prevent the psi from exceeding the point that it is set at. I do believe that if I turned the propane all the way up that this pressure relief valve would not be able to prevent my tank from exceeding the 2 psi that I am able to set it at. This is not a proven fact because I have not tested it. I'm just judging by the amount of pressure that this valve actually relieves. It relieves enough pressure that I don't try to find a better relief valve. But if I wanted to be perfectly safe i would wish for a valve that relieves more pressure so that to be sure that it would be impossible to exceed the 2 psi mark that I can set it at using this valve.

Seems to work great! I had it set at 75, and it didn't leak at 50PSI.
Seems to work great! I had it set at 75, and it didn't leak at 50PSI. The spring loaded design looks like this design should be fairly robust and fool proof. I heard that it leaked for some people, but my application didn't. I used thread tape and never opened it all the way up, so it seems to work for me.

Leaking Valve FIXED
Like others, my PRV developed a leak out of nowhere (it would never fully close). I removed it from the fitting and found that a small piece of thread tape had become trapped in the valve seat, causing the leak. After removing this and reassembling, the leak is gone and the valve operates properly. I would be cautious using this in a setup where any debris could enter the valve. The markings are wildly wrong, but with a gauge in the system this is easily set to low pressure (10 PSI). I do not know if it would work toward the higher end of the rated range.

Tested positive for lead content
This device seems well made and durable, but if you are intending to attach it to a beverage line or passing liquid near it that is intended for consumption, think twice. Having read about various factories mixing lead in their brass, I decided to buy a reliable lead testing kit and tested all my recent brass connector purchases. Four out of 16 items tested positive for lead content. This item was one with lead in it. Photo provided with a sample of many items I tested.

Excellent piece of hardware
Bought for a safety valve on a science project. Nice fine adjustment. Doesn't leak until set point is hit. Closes tight when pressure goes below set point. Tested with some pretty fast transients and it worked great. Could have done without the factory installed thread sealant.

Does the Job
I use it as an emergency air pressure release to bleed off back pressure from my Medo LA45C pump for my guppies LOL. Set it to open at 1.5 PSI I actually dump excess air through a ball valve and huge 1/5" x 8" airstones so my backpressure on the ball valve is set to 0.5PSI . but if airstones plug up this valve opens to keep back pressure from blowing my piston rings on the Medo.
