Expert advice on machine safety – always on the safe side

There are no easy answers to defining a security concept. Each case is different, and tailored solutions need to be found for each customer's special requirements. AVENTICS therefore offers customers more than general machine safety training. We aim to work out solution approaches with you directly on site. Our proven experts will be happy to call and provide competent advice on pneumatic control technology.

AVENTICS offers comprehensive machine safety services. Benefit from our expertise.

Machine safety prevents industrial accidents

AVENTICS has extensive, long-term experience in designing pneumatic controls. Based on this expertise we set standards in plant safety. Our pneumatics products impress with a host of technical safety features that help to avoid industrial accidents. This includes the following functions: safe stopping and closing, safe operating stop, safe brake control, safe energization, and safe exhausting.

Circuit example for safe exhausting to ISO 13849-1

Circuit example

The basic valve position depressurizes the system.

Redundant safe exhaust is guaranteed via two exhaust pathways:

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

Safe exhaust

Design features:

Basic and proven 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 (redundantly).
  • There are monitoring elements in addition to the functional block diagram.
  • Drive-related hazards are not taken into account.

AVENTICS supports your design efforts with a series of further circuit examples positively rated by the IFA. Our document on the application of EN ISO 13849-1 to electropneumatic controls provides 13 examples of how to adopt effective measures against potential hazards through the implementation of pneumatic safety circuits.

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.

AS series maintenance units

AS series maintenance units

The cost-effective solution for 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 machine or plant section exhaust.

Directional valves from AVENTICS

IS12-PD series ISO valve

The variable solution for 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

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.
