Features Using high-quality steel plate for precise cutting, one-piece molding, high strength and wear resistance. High‑accuracy hole spacing and cylinder diameter settings, standard size, not easy to fall apart after installation. Thickened and reinforced design, durable and pressure resistant, often used in air compressors. Once the piston begins to travel up the reeds, the valve plate opens up and air is sent in to the air tank of the compressor. Compressor reeds will wear out after long-term use, and the valve plate is the best choice to replace old or damaged parts.
