Ammonia vapor pressure reducing valve
Thread Content
Are there any pressure relief valves for ammonia vapor water steam? The existing ammonia vapor mixture has an ammonia mass fraction of around 90%; before pressure reduction, the pressure of the ammonia vapor is approximately 10–15 bar, the temperature is about 80°C, and the vapor flow rate is around 10 m3/h. It is necessary to reduce the pressure to 3–5 bar, with the pipe diameter being around 38 mm (this value can be adjusted). What type of pressure reducing valve can be used for sampling? Thank you!

However, I’m not very familiar with the use of ammonia vapor mixtures as the working medium in such valves; typically, the valve body is made of ductile iron, while the diaphragm is made of phosphor bronze. The valve body can also be made of cast steel, but the price is relatively higher. For more details, please visit http://ou-ray.com/series2002.html
There’s no problem with this; Mankenberg in Germany produces stainless steel valves designed for use in the chemical industry, and the diaphragms are made from materials suitable for the client’s specific medium! If you’re interested, we can discuss it in more detail.
GP-2000 pressure relief valve; those with DN32 or DN40 sizes should be available at http://www.yoshitake.co/product/html/?83.html
The ammonia vapor pressure reducing valve might be different from a regular steam pressure reducing valve, you know?
