Valve seat coating materials from Suzhou Kaitianfu Machinery Co., Ltd are engineered for detachable surface components that support valve spools in the closed position, forming a sealed interface. The product uses a tungsten carbide-cobalt-chromium (WC-CoCr) composition with a chemical breakdown of 86% WC, 9-11% Co, 3.5-4.5% Cr, and 3.5-4.5% C, designed for high wear resistance in industrial valve applications.
The coating is applied with a maximum thickness tailored to valve seat dimensions, achieving a hardness of HV0.3 typical for WC-CoCr alloys. Bond strength exceeds standard requirements for metallurgical adhesion, with porosity controlled below industry benchmarks to ensure durability under cyclic thermal and mechanical loads. This composition is standard for valve seats in oil and gas, power generation, and chemical processing where erosion and corrosion resistance are critical.
These coatings are used in gate, globe, and check valves across industries requiring reliable sealing under extreme pressures and temperatures. Buyers typically source in bulk for OEM valve manufacturing or aftermarket refurbishment. Confirm packaging, lead time, and bond strength test certificates with the supplier, as these are critical for quality validation before installation.

Before ordering, verify the coating’s chemical composition and thickness match your valve’s specifications, as these directly impact sealing and durability. Request third-party test reports for hardness, bond strength, and porosity to ensure compliance with industry standards like ASTM B768.
Confirm logistics details such as lead time, which may vary based on batch size and substrate preparation. Common Incoterms for this product include FOB Ningbo or Shanghai; payment terms often require a 30% deposit with the balance due before shipment. Always clarify these in writing.
Inspect the coating’s surface finish and adhesion upon receipt using non-destructive methods like holiday testing. Require a material test certificate (MTC) and a conformity certificate for the batch. For critical applications, arrange an independent laboratory analysis to validate the WC-CoCr composition and structural integrity.
