ATEX set ventila sa SIPART PS2

ATEX Valve Set w/ SIPART PS2 ATEX Valve Set w/ SIPART PS2

Complete automatic control valve section consisting of Armatec pneumatic actuators, Siemens SIPART PS2 positioners and ASCO Numatics solenoid valves.
The valves were used in an industrial oxidation/steam/condensate system and are suitable for PLC/DCS-controlled process applications.
The set includes 12–14 valve units, each fully assembled and ready for “plug-and-run” integration. All actuators and positioners are ATEX-rated, making them suitable for hazardous zones (gas & dust).
Removed from a modern industrial installation in Elektrėnai (LT). All components are premium European brands and designed for continuous heavy-duty operation.
