With the compact, lightweight design of its AV Advanced Valves, AVENTICS (formerly Rexroth Pneumatics) says it has set new benchmarks for pneumatic valves that allow for advanced construction concepts. In addition to the AV03 and AV05 valves forming a base, the modular system design ensures a high degree of flexibility. Visitors to the Motek in Stuttgart, Germany, can see for themselves at the AVENTICS trade fair stand from 6–9 October 2014.
After the successful market launch of the AV03, AVENTICS has expanded its AV product family to include the AV05 (with a maximum nominal flow of 700 l/min). As with the AV03, the AV05 is claimed to be up to 45 per cent smaller than similar valves on the market. Wolf Gerecke, Head of Product Management at AVENTICS, says: "The modular range consists of much more than the two valves. Customers who last saw the AV03 one year ago will be surprised at all the new features the AV system now offers – we have consistently added new options."
Compared with previous valve systems, the AV family features:
- fast switching times
- low weight
- compact dimensions
As with the AV03, the flow in the AV05 valve system has also been optimised. Gerecke explains: "The valves can be mounted closer to where compressed air is required."
For the AV family, modularity was also at the top of the priority list. Wolf Gerecke reports: "We wanted to expand the application options for the AV valves while reducing the complexity of the logistics and design." As a result, double and triple base plates can be combined, enabling the use of any number of valves with only two types of base plates.
The electrical connections accommodate the required modularity while the decentralised fieldbus connection to the Advanced Electronic System (AES) also does its part. The AES processes analogue as well as digital signals, facilitating fast assembly and flexible use. Up to 36 valves in a valve block can be actuated via the multipole connection. The D-sub connection is available with two exit directions, allowing the valve block to be optimally integrated into the system.
Smaller, faster, lighter
AVENTICS launched its innovative AV03 valve under the name of Rexroth Pneumatics. The multi-patented product, which is the result of intensive research, has a maximum nominal flow of 300 l/m. Gerecke says: "We called all known principles of design, materials and assembly into question during the development of the AV series." First, the valve components in the housing are arranged diagonally, saving up to 45 per cent more space. Second, shorter distances between the actuator and valve allow for compressed air savings of up to 20 per cent - plus faster switching.
Gerecke notes: "The unique design clearly shows the innovative leap our AV family takes in pneumatics. The concept required much more work and expertise than simply the idea of using the maximum length in a specified geometry. For example, high-tech polymers were implemented and a new injection moulding process was developed specifically to be able to realise the design principle. The new materials make the product up to 40 per cent lighter.”
- Small and lightweight – the valve can be placed closer to the actuator
- Modular system design facilitates construction
- Faster switching times and higher efficiency thanks to short distances and optimised airflow
AVENTICS will present its AV series at the Motek international trade fair for automation. Visitors can find out more about the advantages of the AV valves in hall 3 at stand 3305. For more information go to www.aventics.co.uk or www.advanced-valve.com.
