Exhaust Valve, AS3-SV

Published on : Tuesday 30-11--0001

In times of digitalisation, machine safety still remains a priority issue for industrial manufacturers. With its new safety valve, Aventics has a reinforced its range of products in this area. Users can integrate it modularly into AS series maintenance units or position it flexibly as a stand-alone product. Thanks to the redundant structure and two-channel signal processing with self-monitoring, users can achieve category 4 safety-relevant controls with the new AS3-SV while meeting the maximum performance level "e" (PLe) according to ISO 13849-1. In addition, the AS3-SV’s soft-start function gently moves the actuators into their initial position and then switches through to full working pressure. Here, the technician uses an adjustment screw to adapt the time for switching to full pressure. Full pressure is switched at a value of around 50 percent of the input pressure. The operator can also override slow pressurisation.

Safe inputs, outputs, and controls are already integrated in the new product. As a result, machine manufacturers and system integrators can implement the safety electronics in hardware and software without any additional effort.
