For high-precision grinding and on-site maintenance of safety valve seats and valve discs.
The Relief Valve Grinding Tool is a professional on-site maintenance solution designed for precision grinding and refurbishment of safety valve sealing surfaces.
By combining the advantages of manual grinding accuracy with stable electric drive support, this tool achieves high-precision valve seat and disc grinding that cannot be reached by conventional electric grinders. It is portable, easy to operate, and suitable for various types of safety valve maintenance tasks.
The Relief Valve Grinding Tool consists of a grinding head, grinding plate, and fixed auxiliary tools, forming a complete solution for safety valve maintenance.
The OYM-150T Safety Valve Grinder adopts a dynamic grinding method in which the valve body rotates while the mold is manually guided, ensuring accurate surface fitting and consistent grinding results.
This design retains the precision advantages of manual grinding while significantly reducing labor intensity and improving efficiency. The equipment supports multi-track grinding and is suitable for a wide range of valve sizes and flat metal sealing surfaces.
