Этот предохранительный клапан Control Devices CR25-100 имеет латунный корпус, регулируемое давление сброса, входное соединение с наружной резьбой 1/4 NPT и уплотнительное кольцо из фторуглерода. Латунный корпус клапана, латунное седло клапана и тарелка из нержавеющей стали устойчивы к коррозии и могут использоваться при рабочих температурах до 250 градусов по Фаренгейту. Клапан можно отрегулировать для открытия в диапазоне от 0 до 100 фунтов на квадратный дюйм с помощью нейлоновой ручки микрометрического типа. Этот предохранительный клапан имеет скорость потока 6 стандартных кубических футов в минуту (SCFM) и подходит для приложений сброса давления с низким расходом, таких как воздушные компрессоры без бака. Предохранительные клапаны удаляют избыточное давление или вакуум из системы. Отверстия клапана позволяют жидкости или газам выходить для снижения давления, а затем закрываются, когда клапан достигает предела давления повторной посадки. Они также сбрасывают избыточный вакуум, открываясь для выпуска газа в систему, а затем закрываясь после того, как он достигает предела низкого давления. Некоторые предохранительные клапаны имеют механизм регулировки для установки давления при открытии клапана, что делает его пригодным для различных применений. Предохранительные клапаны оцениваются в зависимости от объема жидкости или газа, который может пройти через них, а материал, из которого изготовлен клапан, должен подходить для жидкости или газа, которые могут быть коррозионными или иметь экстремальную температуру, в которой он работает. Предохранительные клапаны используются в различных областях, таких как воздушные компрессоры, нефтехимическое и химическое производство, переработка природного газа и производство электроэнергии. Control Devices производит клапаны и другие устройства управления потоком. Компания, основанная в 1963 году, имеет штаб-квартиру в Фентоне, штат Миссури.

Нейлоновая ручка микрометрического типа для регулировки сброса давления. Силиконовое уплотнительное кольцо обеспечивает герметичность в пределах 10 процентов от установленного давления. Конструкция из латуни и пружина из нержавеющей стали для защиты от коррозии. Входное соединение с наружной резьбой 1/4 NPT. Давление сброса регулируется от 0 до 100 фунтов на квадратный дюйм.

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.
