GEA Nu-Con has responded to feedback from their customers by introducing several new improvements to their range of rotary valves.
The improvements they have introduced include:
New Extractor Cap Cover / Positioner
By redesigning the extractor cap to be a transparent unit, GEA Nu-Con has incorporated indicator marks into the barrel to enable the maintenance operator to accurately align the rotor for engagement onto the motor. By doing this, they have also eliminated the need for the rotor indicator disc and O-Rings which not only reduces cost, it also reduces the need for maintenance and fiddly adjustment.
- Easy viewing direction of rotation
- Easier Rotor alignment
- Fewer parts to maintain
New Air service Unit
The air service unit has been relocated to improve installation and to reduce wear and tear during the life of the unit. As a result, the vent port is now un-obstructed. With a 0.01µ filter, this also provides increased product safety giving the customer greater peace of mind.
A larger airline provides greater flow to the unit and will prolong the seal life.
- Protected location
- Vent port un-obstructed
- 0.01 micron filter
- 8mm airline size
In addition to the main improvements, there have also been several other modifications which have contributed to improved operation and price reduction.
- Modified seal retainer thumb nut (Hex machined head) makes it easier to tighten with hand-tools if required.
- Modified convey transition sealing (recessed for 2-way sealing) which provides better sealing for high pressure systems.
- Modified rotor lead in (chamfered keyway) makes rotor alignment much easier and thereby reduces the potential for drive sleeve damage.
In all, GEA Nu-Con expect that the above improvements will be well received by their customers and welcome feedback so that they can continue to deliver world class products to the market.
