This precision multi-hole valve core component is primarily designed for the distribution, throttling, and steady-state control of gases or liquids, imposing extremely stringent requirements on dimensional consistency and internal channel precision.
During the inspection stage, critical dimensions including outer diameter, inner bore, threads, and lateral hole positions are subject to rigorous control. After machining, digital calipers and micrometers are adopted for 100% inspection or sampling inspection of outer diameter and length to ensure dimensional stability. Functional verification of inner bore and lateral hole positions is conducted using pin gauges and go-no-go gauges, guaranteeing smooth assembly and unobstructed fluid channels. For key geometric tolerances such as coaxiality and hole spacing consistency, profile projectors or coordinate measuring machines (CMM) can be deployed for detection, thus ensuring that the multi-hole structure delivers excellent fluid symmetry and stability post-assembly.
All components must undergo deburring and cleaning prior to delivery to prevent residual burrs or impurities from compromising the reliable operation of the fluid system.
In terms of application fields, such components are widely used in gas control and distribution systems, liquid delivery and metering devices, precision valve body assemblies, and industrial nozzle systems. They are commonly found in automation equipment, medical devices, environmental protection and analytical instruments, energy and chemical engineering equipment, etc.
Their multi-hole structure enables balanced flow distribution, pressure buffering, and stable output, making them suitable for working environments with high requirements for flow accuracy, response consistency, and long-term reliability. These components serve as key functional parts in high-end fluid control systems.
