New Bosch Rexroth advanced valve takes performance to next level

Nov. 11, 2013 - PRLog -- The result is a lower pressure drop across the system, and optimised performance.

Technical designers always try to position pneumatic valves as close to actuators as possible, because shorter tubing lengths reduce the required compressed air by up to 20%. However, common valves are usually too large and heavy for handling applications. With Rexroth's new generation of extremely compact and lightweight Advanced Valve AV03 valve systems, available in South Africa through Tectra Automation, engineers now have a lot more freedom and can arrange pneumatics decentrally, increasing efficiency and performance.

Rexroth has halved the weight of the new valves by using resistant high-performance polymers and reducing the number of parts. The required installation space has also been cut by an incredible 45%.

So how did they do it?
Developers arranged the valve components at an angle and optimised the supply and exhaust channels, thus reducing flow losses. Users profit from a flow improvement of 40%, allowing them to substantially lower the supply pressure and boosting their energy efficiency.

The new valve system also fulfils engineers' demands for customized automation solutions. Starting with the second valve, the number can be increased step by step up to 40 single solenoid valves or 64 double solenoid valves. Nowadays, more and more users also implement different pressure zones in a single valve system to achieve further savings. The new valve systems offer them up to ten supply plates for this exact purpose.

Integration capability
As with the entire range of pneumatic components from Bosch Rexroth, the AV03 provides practically endless connectivity, using multi-pole connectors and field bus interfaces that may include integral I/O modules. Sensors can further be directly connected to the valve’s electronics, which means less cabling is necessary to relay information to the switchgear cabinet.

Light weight and compact designs mean the AV03 can be installed directly onto a gantry system for truly minimal pressure drops.
