The best safeguard: machine safety that prevents accidents

Preventive measures against accidents by designing safe machines are defined by standards and regulations for every production machine. AVENTICS helps you to implement these guidelines and standards and features a wide range of products with all relevant certificates.

AVENTICS, your experienced partner: We provide consulting for all things machine safety in pneumatic control technology, offer comprehensive service in defining safety concepts, and have all the right products with the required documents.

“Machine Safety Expertise for Pneumatics” manual available

We at AVENTICS have developed a forty-eight page manual to help you protect your people, machines and property through better knowledge of how to take advantage of safety-related pneumatic systems and components. The guide covers key topics in the implementation of relevant directives and standards for safety-related pneumatics by using examples, circuit diagrams, discussing hazards and risks (estimate – assess – eliminate), diagnostics, definitions – and product selection suggestions.

Circuit example for safe exhaust

The basic valve position depressurizes the system. Redundant safe exhaust is guaranteed via two exhaust pathways:

  • Via non-return valves 2V2 and 2V3 and directional valve 2V1 (observe minimum opening pressure of the non-return valves)
  • Via directional valve 1V
  • Valve 2V1 must be actuated to extend and retract the cylinder.

Safe exhaust

Design features:

Basic and well-tried safety principles are met for all relevant components. The directional valves comply with the quiescent current principle and have sufficient positive overlap. The non-return valves must be engineered to assume an open state, even with failure, to safely exhaust the cylinder chambers. The switching valve function of 1V and 2V1 is periodically checked by querying the cylinder position switches 1S1 and 1S2 and the pressure switch 2S.

A block diagram is created from the circuit diagram.

The components are arranged

  • in series when the components work together to execute a function.
  • in parallel “channels” if they perform the function independently (redundant).
  • There are monitoring elements in addition to the functional block diagram.
  • Drive-related hazards are not taken into account.
