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.

Products from our range

AV valve system with AES fieldbus system

AV valve system with AES fieldbus system

The AV system offers high performance through a wide range of electrical and pneumatic connection options – and can easily be adapted to the requirements of any safety-related pneumatic control. The high service life guarantees long operating times in safety-related controls without failures or the need for maintenance.

AS series maintenance units

AS series air preparation

The cost-effective solution for safe pressurization and exhaust: The modular versatility of the AS series maintenance units enable universal application. Compact, high-performance, lightweight, and user-friendly: The AS series offers a cost-effective solution for safe machine or plant section exhaust.

Directional valves from AVENTICS

IS12-PD series ISO valve

The variable solution for safe pressurization and exhaust: The electrically operated 5/2 directional valve with spring return according to ISO 5599-1 convinces with high B10 values and an integrated slider position detection. The installed sensor is safeguarded against manipulation.

SV07/SV09 double valves

SV07/SV09 double valves

In safety-relevant controls, the fail-safe double valves enable safe and controlled pressurization and exhaust of machines or machine sections. The solenoid valves mutually monitor their function and are therefore considered intrinsically safe certified components for use in high control categories.

LU6 series

LU6 series cylinder locking units

Static or dynamic braking: The lock element can be used as both a holding unit (blocking of a movement) and a brake unit (emergency stop/emergency off). Proper use has been verified by the IFA (Institute for Occupational Safety and Health) and documented with a BG test certificate.

SM6 analog distance measuring sensors

SM6 analog distance measuring sensors

The SM6-AL analog distance measuring sensor records piston movement over the entire stroke. It enables high-resolution distance measurement and exact positioning in measurement ranges from 107 to 1007 millimeters. The robust aluminum housing, as well as a cable sleeve support, guarantee a long service life and reduce maintenance costs.
