Valve system

Solution for elementary pneumatics

With the launch of the ES05 essential valve system series, Aventics offers a solution for applications with typical requirements in industrial automation. The valves can be controlled via CANopen.

Designed to reduce the number of components, the assembly of the ES05 valve system can be completed with one single tool. It also reduces the risk of faults. Paul Cleaver, chief executive officer at Aventics (Germany), explained what led to this development: “Our customers asked for a simple, components reduced, flexible, and efficient standard valve – tailored to their application.” The series therefore focuses on ease of handling for distributors, machine manufacturers, and system integrators. They configure their customized solution online from a set number of readily available components. “Assembling a valve system has never been faster or easier,” explained Paul Cleaver.

Aventics opted for a modular system for the ES05. Orders are supplied as complete assembly kits. All components are unique, which makes incorrect installation harder and only one tool is required for the job. All fittings are of the same type and tightened with the same torque, which further simplifies assembly and prevents errors. The portfolio also includes the Essential Test Box. With this test box, the correct function and leak-tightness of the valves can be tested before installing the valve systems. This is particularly useful for volume users and distributors.

The valves come in a robust housing made of high-performance polymers and are stable and compact. Users connect the end and base plates and can extend the system in pairs up to twelve single or double solenoid valves. The valves are controlled via single wiring with a form CI plug, a D-Sub connection with 25 pins, with AES valve electronics, or an integrated IO-Link interface. AES supports fieldbus and Ethernet protocols, including CANopen and Devicenet.

If necessary, the pilot coils can also be turned at a later stage to realize mixed connection configurations. With a switching time of under 35 ms for all valve functions, dynamic action is guaranteed for short cycles. With single wiring, the ES05 complies with protection class IP65, so the valve system can also be installed in decentral locations, even in environments exposed to splash water. All other connection types comply with protection class IP50.

Aventics is a globally active manufacturer of pneumatic components and systems. The company is also a specialist supplier of drive and control solutions for the marine industry and commercial vehicles, as well as inverted tooth chains for production processes. Since the start of 2014, the former subsidiary of Bosch Rexroth has been operating as a standalone company. The company employs approximately 2100 staff worldwide.
