High-Impact Forged Alloy Structure: Manufactured from high-grade 20CrMnTi/ASTM 8620 alloy steel via closed-die forging. This process eliminates internal porosity and grain defects, providing superior tensile strength and impact resistance under severe hydraulic pulsation.
Deep Carburized Heat Treatment: Case-hardened through advanced carburizing and quenching processes to achieve an operational surface hardness of HRC 58-62. This drastically improves resistance to erosive wear caused by high-velocity sand and drilling fluid slurries.
Precision-Ground Sealing Surface: The taper contact area is finished using high-precision CNC grinding machinery to guarantee a fluid-tight seal with the valve body, preventing high-pressure fluid washouts and operational downtime.
API 7K Standard Dimensional Interchangeability: Built strictly to API Spec 7K manufacturing tolerances, ensuring seamless 100% direct-fit replacement for major global mud pump models without requiring modification.
Industrial Applications
Oil & Gas Onshore Drilling Rigs: Essential fluid end expenditure component for high-pressure triplex mud pumps in land-based deep well drilling.
Offshore Drilling Platforms: Heavy-duty fluid circulation components suitable for harsh offshore and marine drilling environments.
HDD (Horizontal Directional Drilling) & Mining: High-durability valve assemblies used in trenchless technology and geological core drilling mud pumps.
