June 12, 2019 – Festo has developed new advanced solenoid valves and coils for the petroleum and chemical sectors that the company says increase process safety.

VOCD/VOFD solenoid valves can be used in many demanding applications and meet the highest safety standards (up to SIL3, explosion protection). These electric valves are backed by German Technical Control Board (TÜV) certificates up to SIL3 in accordance with IEC 61508.

The surface of the valve housing is treated with the Ematal process for resistance against atmospheric and chemical degradation both indoors and outdoors. Ematal anodizing creates a hard aluminum oxide layer with titanium oxide intercalations, which makes the valves resistant to wear and abrasion and allows for sliding.

The 3/2- and 5/2-way VOFC/VOFD solenoid valves are intended for controlling and safe deactivation of pneumatic drives in potentially explosive areas of chemical and petrochemical plants. The NAMUR flange pattern makes the solenoid valves suitable for quarter-turn actuators. The integrated spring chamber ventilation function protects quarter-turn actuators with spring return (single-acting cylinders and actuators) against contaminated ambient air and weather influences.


The solenoid coils from the VACC series are available for ignition protection types: Ex e mb, Ex ia, Ex db, and Ex d.

Local and regional certifications are available.
