Polymer Replaces Metal Poppets in Valves
Manufacturers of check valves and pressure relief valves for hydraulic and pneumatic compressors are constantly looking for ways to improve the performance of their products. Valve performance, more than any other component, determines compressor efficiency. To achieve improvements such as reduced fluid leakage, noise reduction, longer valve life, and cost reduction, the metal poppets in the valves are being replaced with poppets made of PEEK polymer—a high performance thermoplastic. Substituting plastic for metal maintains strength while improving corrosion resistance, reducing weight, and allowing for greater design flexibility.
