DG Quick-Clean rotary valve

• High-duty rotary valve
• 24/7 industrial applications
• Frequent cleaning and inspection
• Protective system up to 10 barg

TBMA DG Quick-Clean rotary valves are specially designed for processes where frequent cleaning and inspection are required. The type DG valves are available in both drop-through (H-ARDG) as well as blow-through (H-GRDG) version.

Easy inspection and cleaning | Due to the double-bearing construction, the rotor can be easily and safely removed and manually turned in pulled-out position. This way the rotary valve can be wet or dry-cleaned internally. The removed rotor can be turned and dry-cleaned. The guiding bars are long enough to give the operator ample access for inspection and cleaning of the inside of the valve.

Self-seeking shaft | The bearing construction guarantees a clearance-free run of the rotor and prevents damage when (dis)assembling. Contrary to valves of other brands, the TBMA Quick-Clean valves are equipped with a spline shaft. This means that after cleaning, the rotor can be quickly and easily mounted through the self-seeking shaft. The rotor adjustment is fixed and needs no readjustment after (dis)assembly.

Minimal chance of damage | Because of the clearance-free suspension and fixed adjustment, any metal contact of the rotor is practically impossible. Moreover, the chance of damaging the rotor tips and/or the inside of the valve during (dis)assembly is limited to a minimum. This is particularly important for hygienic applications. In addition, the shaft seal cannot be damaged, because the spindle with spline remains in place when the rotor is pulled out.
