Indirectly controlled pilot valve for particularly demanding operating conditions. Redundant version for safety systems up to SIL3. Suitable for process automation in the chemical and petrochemical industries Suitable for outdoor use under harsh ambient conditions Especially suitable for quarter turn actuators thanks to NAMUR flange pattern Valve can switch between internal and external pilot air Variants with safety functions Variants to EU Explosion Protection Directive (ATEX) Tried-and-tested quality. The pilot-operated solenoid valve VOFC has an excellent safety concept and can be used everywhere. That is why it is used in world-leading chemical, petrochemical and pharmaceutical production lines, as well as in the oil and gas industry, making it the favourite choice for controlling single- or double-acting valve actuators. The solenoid valves are also extremely reliable and safe in fail-safe functions for safely switching off valve actuators with positioners. Functional safety in the process industry Safety devices in process industry plants are needed to reduce the hazards created by these plants for people, the environment and property down to the lowest possible, acceptable level. As a general principle, the more hazardous the plant, the more reliably its safety devices must operate in case of an emergency. Once a SIL level has been assigned to a plant, specific installation principles must be observed, e.g. redundant design. This enables the risk to be reduced to the greatest possible extent in the event of a malfunction.
