Selfcentering Steady (Option) Selfcentering steady rests are available to fit on the swivel plate slideway for additional support of long stem valves. Both the workhead and the stready rest are adjustable along the swivel plate to clamp each valve on that part of the valve stem which normally travels in the valve guide. The combination of collet chucking and the unique Hunger steadying provides double support of long valves to ensure the ultimate in valve refacing accuracy. Oscillating Equipment (Option) An oscillating equipment for automated power traverse of valve face across the grinding wheel is available to ensure efficient stock removal and superior finish. The stroke of oscillation is infinitely adjustable. Automated Infeed (Option) Power infeed is available for automatic grinding according to a preselected program. The feed rate, the total infeed and the sparkout time can be easily selected.

The sliding gate motor valve type 8038 in reinforced design with highresolution fast actuatoris suitable for a wide range of process applications. Media such as steam, liquids, gases, etc. can be handled precisely. The interaction of highprecision control electronics with the precise stepper motor results in a positioning accuracy of ± 0.2% even with a valve stroke of only 6 mm. By means of supercapacitor technology, in the event of a power supply failure, the valve returns to its defined basic position. Metal bellows Position electronics Analog stroke feedback Limit switch Fail safe feature
