Prince RDRS-150-16 Flow Control Valve, Adjustable Pressure Relief, Cast Iron, 3000 psi, 0-16 gpm, 1/2" NPTF List Price: $132.50 Sale Price: $88.15 |
|
The Prince valve models RD-100 is pressure compensated adjustable flow control valves. By rotating the handle, the flow out the “CF”, or controlled flow port, can be varied from approximately 0 to the maximum controlled flow shown in the chart below. Any remaining flow is bypassed to the “EF” or excess flow port. This flow can be used to power another circuit or can be returned to tank. Once the controlled flow is set it will remain nearly constant with variations in pressure on either the controlled or excess flow ports. Please note: If during operation the controlled flow port is blocked the valve will compensate in such a way as to shut off flow to the excess port. These valves can also be used as a restrictive flow control by plugging the excess flow port. The Prince valve models RDRS-100 have a built in adjustable pressure relief. For these models the excess flow port must be connected to tank. |

Here are some more information for Relief Valve:
The many types of existing gas valves can easily give you, the homeowner, a quick headache, but there is an answer: the universal gas valve. No more confusing choices, because a Honeywell, universal gas valve is compatible with each and every system. You may want to take a look at the universal Honeywell VR8304 Gas Valve right away.
Gas valves are devices that regulate gases such as natural gas and liquid propane. Used for several applications gas valves are available in a variety of sizes flows, inlet and outlet ports, and pressure ratings. One is made of plastic such as polyvinyl, polytetrafluoroethylene, chlorinated polyvinyl chloride, or a metallic substance such as brass, bronze, steel, iron, copper, or aluminum, to name a few. If you are not interested in a universal gas valve, be sure to have your type and model number ready to start narrowing down your options and making your final decision.
Solenoid, electrically actuated ball, proportioning, elliptic, pinch, check, diaphragm, elliptic, metering, needle, plug, pressure relief, and stopcock are all types of valves with specialized characteristics to choose from. Valves come with different sealant materials as well. Some of these are NBR (Buna-N), EPDM (Ethylene Propylene), FKM (Viton), and PTFE (Teflon). NBR is the most common sealant and used for temperatures from 0 to 180 degrees Fahrenheit. EPDM is for hot and some fluid applications, in the temperature range of -10 to 300 degrees Fahrenheit. FKM is specifically for hydrocarbons such as gasoline and its temperature range is from -10 to 300 degrees Fahrenheit. PTFE is used for many temperature ranges as it is the most chemical resistant sealing material. Certain valves are specifically designed for an individual product or product line, so if a name is unrecognizable from what you have discovered from this information, this could be the type of valve you have come across.
First of all, you need to differentiate between your system type, liquid or gas, and match the necessary valve material. When pressurized gases are involved, it is necessary to use a metal valve. Teflon is appropriate for stronger, more corrosive chemicals. Next, decide between the pressure and flow rate your system will require. (Metal can handle higher pressure.) Also keep in mind that solenoid valves are best for continuous on/off cycling and ball valves are easiest to maintain. Finally, decide on a normally closed or normally open gas valve depending on how often you expect your valve to be in use. Some factors to also consider when choosing your gas valve are pipe size, orifice size, pressure and vacuum range.
Terms to remember are the PSIG-maximum pressure and INHG-maximum vacuum. Maximum pressure indicates the amount of substance that can safely flow through the valve, but can also be affected by temperature or chemical makeup of the gas substance. Maximum vacuum indicates the top vacuum pressure that the valve is capable of operating, also affected by temperature or chemical makeup at times.
Proper sizing is key when replacing your gas valve, so be aware of NPT (National Pipe Thread ports) and orifice sizes as these are important in indicating how much fluid is able to flow through the valve. Again, for one of the easiest ways to go, we suggest trying a universal gas valve, where you can forget the chances of making a mistake in sizing or maximum pressure.

Open Some of your Pressure Valves
Our Lord inspired me to write this article to offer practical ways to let off steam without adverse effects.
Oddly, one of the first things that came to me was to eliminate any feeling that some of us might have to feel pressured to be "in style." Think about it. Most of the time, being "in style" causes people to look ridiculous.
I mean it causes older people trying to look young again to become laughingstocks. It causes younger people a lot of mental and financial pressure trying to maintain stylishness. And it causes overweight people to look even more so!
Years ago I also was caught in this same web. One year the hemlines were around the ankle, the next around mid-thigh. I was a single mother, and funds were tight, to say the least.
Thank God, one day I woke up and realized the ludicrousness of the situation. I simply got tired of jumping to the whims of the manufacturers (who could not have cared less how I looked), whose sole purpose was profit.
I had had training about ten years earlier in the skills of charm and modelling, which had included learning the styles which optimized my particular build. But, yielding to the pressures of fashion (and succumbing to my naiveté), I had abandoned those tried and true principles for what everyone else was wearing. Duh!
Finally, when I realized how expensive this habit of having to have the "latest" really was, I determined that I would no longer be a victim of someone else's profit margin.
Ever since, I have invested only in quality clothing that is particularly suitable for my figure, frame, and lifestyle. As a result, my clothes are classics that are always in style and appropriate for me.
This is one pressure relief valve that is no longer needed!
The second valve that needs to be opened in many lives is taking back those lives. Fifty years ago life was a lot simpler (and a whole lot easier). Many of the "labor saving" devices we have today had not even been conceived then. And I'm not so sure that they do save labor . . . they may even make life a lot harder by virtue of the fact that we are required to take care of the devices we use to "save" time!
As an example, take the dishwasher. Unless you have a large family or entertain a lot, I would suggest that you wash your dishes by hand as you go along. Otherwise, most of your dishes end up in the dishwasher, either clean or dirty, when you want them. And it takes a lot of time to load and unload the thing. Plus, unless you practically wash them to begin with, they rarely all get clean. Why not just simplify this small task, not let them build up, and if you use a natural soap, your hands will benefit as well.
Next, if you have young children, don't run yourself ragged trying to juggle impossible schedules of running from game to game to dance lessons to music lessons to karate lessons to this-that-and-the-other-thing.
I remember one mother (years ago when I was chauffeuring my own kids around) who had four children, all four of whom were on different baseball teams. She never actually had time to watch a whole game and enjoy it, because she had to keep running to and fro picking up and delivering, etc. She was always frazzled, to say the least.
And the kids themselves end up having frantic lives and never get to enjoy being kids. School is structured enough for them, without regimenting the rest of their time! Back in the "dinosaur" days, Summer days were long, lazy, and relaxed. We seemed to have all the time in the world, and Summer vacation was three whole months long. Today my grandchildren are lucky if they are out of school by the second week in June and have to go back around the second or third week in August!
Add to all of this the running to and fro among parents, step-parents, babysitters, day care centers, and it just becomes overwhelming at times.
It's bad enough when we adults do not take time to smell the roses, but our kids don't even seem to have enough time to learn what roses are!
I believe that Henry David Thoreau gave the best advice that anyone could hear many years ago: "Simplify, simplify."
