Vertical Gate Valve Grinding Machine

Supports multiple process stages including coarse grinding, fine grinding, and polishing with different grit abrasives.

Suitable for various gate valve diameters with flexible adjustment for different valve specifications.

Achieves surface roughness up to Ra 0.4 and sealing face contact ratio no less than 80 percent.

Widely used in valve manufacturing plants for factory outgoing quality control and valve repair workshops.

Detailed Product Description Brief Points

1 Vertical Gate Valve Grinding Machine processes sealing faces of gate valve bodies, wedges, and seats for various gate valve specifications.

2 Grinding principle: rotating grinding spindle with precision feed mechanism grinds the sealing face; optional planetary transmission allows the grinding disc to revolve while grinding tools rotate, creating orthogonal mesh patterns on the sealing surface for superior finish.

3 Station configuration: vertical single-station design with liftable and rotatable grinding spindle for flexible operation.

4 Vertical Gate Valve Grinding Machine is compatible with various abrasive materials including sand cloth, sand paper, and diamond grinding discs in grit sizes from 80 to 1000 mesh.

5 Achievable surface quality: from initial surface condition, finished surface roughness reaches Ra 0.4 with sealing face contact ratio no less than 80 percent.

6 Control system: equipped with variable frequency speed regulation, enabling stepless speed adjustment from 30 to 400 rpm for optimal grinding parameters.

7 Spindle adjustment: range of 0 to 50mm, arm lifting height up to 800mm or more for accommodating various valve sizes.

8 Ease of use: lightweight and flexible operation, low labor intensity, one operator can manage multiple machines simultaneously.

9 Core advantage: grinding efficiency is 10 to 30 times that of manual grinding, significantly reducing labor costs and production lead time.
