Operation Guide for Portable Safety Valve Lapping Machine

Preparation: Clean the valve seat thoroughly and select the correct grinding head or disc for flat or cone geometry.

Mounting: Secure the machine firmly on the valve body or flange using the universal clamping system.

Adjustment: Set the grinding diameter, angle, and depth precisely according to the valve specifications.

Lapping Process: Apply suitable abrasive (diamond paste or discs) and operate at the recommended speed for controlled, even material removal.

Inspection & Completion: Verify surface quality with a straightedge or roughness tester; perform final passes until a mirror finish is achieved, then conduct leakage testing.

The process is user-friendly, requires minimal training, and can typically be completed quickly even during short plant shutdown windows.
