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.
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.
