Air Compressor Assembly Peek Valve Plate Accessories

What is a Valve Assembly?Valve assemblies typically include the entire fluid control mechanism and its housing, electrical or mechanical actuation mechanism, and any associated connectors, external sensors, and fasteners. PEEK is a special high temperature resistant thermoplastic polymer material developed by the British ICI company. Because of Air Compressor Valve Plate Accessories high temperature resistance, corrosion resistance, chemical resistance, and abrasion resistance, it has become a key material in many high-tech fields.

Its main technical level Indicators and characteristics such as
