Technical upgrade of compressor air valves
Thread Content
Due to the company’s technical upgrades to its components, the valve plates used in the original reciprocating compressors were made of stainless steel. Finally, it is considered to use PEK (a special industrial plastic) as the material for the valve disc. Please, experts, share your opinions on whether it can be replaced. Equipment operating conditions: Process gas: hydrogen (containing 500PPM hydrogen sulfide); Temperature: 50–130 degrees ； Pressure: 15MPA

If the temperature inside the chamber of a Pek valve is high, it is prone to damage; however, only a small piece may fall off, which leads to a decrease in efficiency and an increase in temperature. In such cases, the compressor’s operation isn’t affected for a short time, but if the damage becomes more severe, the valve needs to be replaced. Generally, we replace it every 3–4 months, especially under more severe operating conditions.
For the units of model H223R in our company, the air valves used in sections one, two, and three are made of PEEK material; they can last for over a year, which is great. Our electrostatic precipitators, on the other hand, are not that good.
Of course, there’s no problem. We have made many modifications. PEEK valve discs inherently have superior performance compared to steel valve discs. I specialize in manufacturing compressor accessories in Wenzhou, including air valves, piston rings, valve discs, gaskets, and more. Feel free to contact me if you need anything.
PEEK is better; hydrogen sulfide is corrosive, and stainless steel can also be corroded. You’re talking about pressure; when designing gas valves, it’s crucial to consider the pressure difference between intake and exhaust!
What’s the actual effect? Is it mainly because of the good mechanical properties? What other excellent features does Pek have? What about thermal stability, tensile properties, and corrosion resistance?
It is generally multi-stage compression: 2-4-8-16
