Detailed description

Plane light band tester Adopt 220V/50Hz special monochrome sodium light source irradiation; choose 1 grade precision plane flat crystal; applicable to valve sealing surface grinding flatness effect detection, increase the success rate of valve maintenance.

Flatness refers to the plane formed by the sealing surface of the valve seat or valve flap, i.e., the ring ribbon-like whole, and the flatness confirmed by it.

Good flatness means that the sealing surface does not have depression, protrusion or drift surface.
