Can a pressure reducing valve for compressed air reduce the pressure from around 0.6 to 0.08 MPa instantly?
Pressure regulators for compressed air are generally capable of reducing high-pressure air to a lower pressure, but the specific range of pressure reduction is limited by the design and specifications of the regulator. The pressure reduction from 0.6 MPa to 0.08 MPa is significant, and it may be necessary to use a suitable pressure regulator to achieve this. It is recommended to carefully read the product manual or consult the manufacturer when purchasing a pressure relief valve to ensure it meets your needs. .
It’s possible; for compressed air, use a pneumatic pressure reducing valve. The outlet pressure is set to zero by default, and it can be adjusted from zero up to the maximum value
Search for pressure relief valves on Taobao, and then ask the store manager – they are more professional in selling such products.
This generally cannot be used properly.
It’s achievable, but it’s difficult to use it stably over the long term. Generally, after about a year, the export pressure becomes uncontrollable and rises significantly above the set value
Mechanical ones definitely won’t work; a large change in air volume causes the pressure to become unstable. Such situations are rare in engineering; they result in high energy consumption and are not economical. Can’t it be used with low-pressure air compressors – is it designed for use only with those?
Sure. But this is generally not done; instead, two-stage pressure reduction is employed to achieve the desired pressure of the sealing gas. This adjustment ensures stability, and there will be no impact from high-pressure gas in the event of failure.
May I ask what is meant by two-stage pressure reduction – does it refer to the use of two pressure regulators for corresponding pressure reduction?
Yes, generally the pressure reduction ratio of a pressure reducing valve can reach up to 10–20 times; if it exceeds 10 times, step-by-step pressure reduction should be considered.
