Machines for grinding and lapping of the pipeline valves dn 50...1000 mm (2...40″)


• machines are designed for grinding and lapping of the flat sealing surfaces of the housings and wedges of the gate valves, housings and spools of the stop valves (globe valves), safety valves and other flat surfaces.

Treated items

• gate valve; 
• globe valve; 
• safety valve.* 

* Upon customer request.

DN of valve

Stationary units: 
• SPSH-600-N: DN 50…600 mm (2...24″); 
• SPSH-1000-N: DN 300…1000 mm (12...40″). 
Unit with two tilting tables: 
• SPSH-600-NN: DN 50…600 mm (2...24″). 
Table base units: 
• SPSH-300-NN: DN 15…300 mm (1/2...12″); 
• SPSH-300-VV: DN 15…300 mm (1/2...12″).

  • The tilted table with adjustable tilt angle simplifies the installation procedure and allows machining of sealing surfaces at various tilt angles. 
  • The coordinate device ensures the part installation by three coordinates (tilt angle and positioning with respect to the x and y axes). 
  • To make installation procedure of workpiece more simple the column can turn on 290° relatively its base. 
  • Digital indication of spindle rotational speed is provided. 
  • The tool drawer unit allows to store replaceable accessories.
  • Uniform lapping plate and the adapter with eccentric allows to achieve high flatness of the surface. 
  • Machines allow to conduct processing of valve parts on the first of the tables and to execute installation work and valve fastening on the second one (SPSH-600-NN, SPSH-300-NN, SPSH-300-VV). 
  • Rotating table with adjustable axially offset is serving to increase the capacity of sealing surfaces treatment process (SPSH-300-VV). 
  • Lathe three-jaw chuck allows to install the valve bodies and spools of small size (SPSH-300-VV).
