SUPPLY AND DISCHARGE VALVE AIRPLUS SAFELINE SERIES

Product catalog summary

Overview: The Airplus Safeline Series valve is engineered for safety and reliability in pneumatic systems, constructed from aluminum, technopolymer, polyurethane, and steel. It operates with filtered air and typically does not require lubrication.

Construction Characteristics: The valve body, spool, and piston are aluminum, with a technopolymer solenoid operator. Spool seals are polyurethane, and the spring is EN 10270-1 DH steel. It uses a male MP12 4 PIN TYPE A connector for electrical interfacing.

Operational Characteristics: The valve functions with filtered air at -10°C to +50°C and a pressure range of 2.5 to 10 bar. It can be installed in any orientation, with a silencer recommended for noise reduction.

Safety Features: A Hall effect sensor monitors spool position, classified under EN ISO 13849. The single version suits safety circuits up to PL=c, and the double version up to PL=e. It is ATEX certified and complies with the EU Machinery Directive.

Installation and Maintenance: Installation requires specialized personnel, ensuring no voltage during connection. Maintenance involves checking the silencer for obstructions and cleaning with soapy water. Internal maintenance should be consulted with PNEUMAX SPA.

Regulatory Compliance: Complies with EN ISO 13849-1 and EN 62061 standards, ensuring functional safety. Certified by BUREAU VERITAS for type approval and compliance with the machinery directive 2006/42/EC.

Technical Specifications: Features a 24VDC coil with a suppressor diode, a flow rate of 3500 NL/min from port 1 to 2, and 2000 NL/min from port 2 to 3 at 6 bar. Response times are 36 ms for activation and 76 ms for deactivation.

Warnings: External magnetic fields and live wires can affect the diagnostic system. Electrical connections should ensure safe isolation per IEC/EN 60204-1.

Specifications: Activation time: 68 ms, Deactivation time: 79 ms, PL: Up to e, ISO 12238, IP Rating: IP65, SIL: EN 62061 Up to 3, B10d: 7,000,000 cycles, CE Marking: EC Machinery Directive.

Technical Features: Includes pneumatic symbol and dimensions, with electrical connection details for sensor and valve connections.

Safety System Setup: Requires a monitoring device, e.g., SIEMENS 3SK2112, activated by an S2 start/reset pushbutton and blocked by an S1 emergency shutdown key.

Analysis of Malfunctions: The diagnostic system detects valve malfunctions that could compromise safety. Proper programming of the monitoring device is crucial.

Accessories and Ordering Information: Includes pressure gauges with various dial sizes and scales, with ordering codes for different versions.

SUPPLY AND DISCHARGE VALVE AIRPLUS SAFELINE SERIES-2

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 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...
