Dynamic Pressure Valve for Heated Gas Release

In summary: Is there a valve that can be set to open to let hot gas out at a certain pressure, and then close once the pressure drops back down?There is a valve that can be set to open to let hot gas out at a certain pressure, and then close once the pressure drops back down. It is a solenoid operated valve.

Is there a valve that can be set to open to let hot gas out at a certain pressure, and then close once the pressure drops back down?

Edit: Sorry, I'm looking for a valve that will let the pressure build up to a high point, then open to release the gas until the pressure is released, then close again until the system builds up another cycle of high pressure. For example, I pump a cool gas into a closed space and heat it up to 500 degrees, at which point this valve opens up and releases the pressurized gas until the pressure is reduced to the original pressure of the cool input gas, then closes until the next cycle of air reaches 500 degrees.

A regulator. They come in all shapes and sizes.

Whoops, i don't think i described what i needed very well. Lemme edit it.

So a pressure relief valve (that is what it is called)?

A solenoid operated valve is what I think you are looking for. There are many manufactures for this. http://www.ascovalve.com/"

Well, I suppose the question is whether or not you need the pressure to go all the way back down to the original pressure after it vents or just down to the threshold pressure for the valve. There is no need for a complicated and expensive solenoid valve if you just want your system to vent once it gets above a certain pressure and then when it drops back below that pressure to close back up.

What is the purpose of this valve? That would probably net you some better responses.

I work at sea, and on our boilers we have these types of valves. We use them as safety valves to ensure the pressure inside the boiler doesn't get too high.

Ours are mechanically operated using a spring though. Spring is set to compress at a certain pressure, it is normally closed, pressure builds up, gets too high and the valve opens. Then when the pressure is back to where the spring will close, the valve closes.

Might be useful?

I think his edited post made it quite clear that he wants the valve to close again considerably below the threshold level (for whatever reason). Interesting that the boilers have this system, it must be quite large! Where does it vent to? Not the boiler room?

Ahhh, My apologies.

Yeah we are talking big boilers, we need a fair bit of steam for all the heating systems for fuel oils etc. They vent to atmosphere usually via the funnel.
 

FAQ: Dynamic Pressure Valve for Heated Gas Release

1. What is a Dynamic Pressure Valve for Heated Gas Release?

A Dynamic Pressure Valve for Heated Gas Release is a device used to control the release of heated gas in a controlled manner. It is typically found in industrial and scientific settings where precise control of gas flow is necessary.

2. How does a Dynamic Pressure Valve work?

The valve works by using a combination of a pressure sensor and a control system to monitor and regulate the flow of heated gas. When the pressure reaches a certain level, the valve will open or close to maintain the desired pressure and release the gas at a controlled rate.

3. What are the benefits of using a Dynamic Pressure Valve?

Using a Dynamic Pressure Valve offers several benefits, including improved safety, increased efficiency, and better control over the gas release process. It also helps to reduce waste and minimize the risk of equipment damage.

4. What types of heated gases can a Dynamic Pressure Valve handle?

A Dynamic Pressure Valve can handle a variety of heated gases, including steam, air, natural gas, and other industrial gases. The valve can be customized to handle specific types of gases and their corresponding temperatures and pressures.

5. How do I choose the right Dynamic Pressure Valve for my application?

Choosing the right Dynamic Pressure Valve depends on your specific needs and the type of gas you are working with. Factors to consider include the pressure and temperature range, flow rate, and compatibility with the gas. It is best to consult with a specialist to determine the most suitable valve for your application.
