SUPPLY AND DISCHARGE VALVE AIRPLUS SAFELINE SERIES SAFETY AND RELIABILITY

Airplus safeline series Supply and discharge valve General Upon implementation of the AIRPLUS size 3 series, air-treatment units, PNEUMAX develops a supply and discharge valve, with an electropneumatic control and spring-return, fitted with a diagnostic system regarding the state of the valve, with the possibility of creating a double channel to determine the system’s redundancy. The valve, as a safety feature, provides the interruption of the air supply and the exhaust of the air circuit it is connected to. The version with one single channel emphasises the features of an EV 3/2 NC, monostable...

Airplus safeline series Supply and discharge valve Regulatory Framework The purpose of the EU’s Machinery Directive is to define the health and safety requirements in the framework of designing and constructing machinery. Since 2009, the new Machinery Directive has become effective in the European Union. Member countries of the EU are required to implement this standard. The manufacturers of machinery can comply with the Machinery Directive applying the harmonised standards listed in the Official Journal of the European Union. The design and manufacture of safety controls are developed in compliance...

Airplus safeline series Supply and discharge valve single (VS) Example of a safety system by means of a Single valve Please note: the safety valve is not sufficient alone to guarantee the safety function. Its setup requires the use of a monitoring device. In this setup, the SIEMENS® 3SK1112-1BB40 monitoring device has been indicated, activated by an S2 start / reset pushbutton, blocked by an S1 emergency shutdown key. Said monitoring device, by means of the readings of the sensor placed inside the valve (reading made by means of the K1 relay), operates the activation of the valve itself. The...

Airplus safeline series Supply and discharge valve double (V2S) Example of a safety system by means of a Double valve Please note: the safety valve is not sufficient alone to guarantee the safety function. Its setup requires the use of a monitoring device. In this setup, the SIEMENS 3SK2112 monitoring device has been indicated, activated by an S2 start / reset pushbutton, blocked by an S1 emergency shutdown key. Said monitoring device, by means of the readings of the sensors placed inside the double valve, operates the activation of the valve itself. The preliminary estimate and the final verification...
