poppetpilot-operated3/2-way

Directly controlled pilot valve for particularly demanding usage conditions. Redundant version for safety-related systems up to SIL3. • Suitable for process automation in the chemical and petrochemical industries • Suitable for outdoor use under harsh, dusty ambient conditions • Especially suitable for quarter turn actuators thanks to NAMUR flange pattern • Variants with safety functions • Variants in accordance with EU Explosion Protection Directive (ATEX) Safety • Can be used in emergencyshutdown (ESD) applications • Suitable for use in safety-relatedsystems up to and including SIL 3 toIEC 61508 Heavy-duty • The surface of the valve housing isEmatal-coated.
