The process industry recognises different sub-segments with specific demands such as for oil & gas, (petro) chemical, power, water & sewage, pulp & paper and pharmaceutical markets.
Quality and reliability of process valves are of great importance for the safety and output of the production. This applies especially to the severe conditions in the offshore industry or on cold/hot spots around the globe. The solenoid pilot valve therefore, being a critical link in the process valve loop, should be carefully sized and selected to meet precisely the application needs.
Three alternatives for mounting the pilot valve exist:
Pilot valve directly mounted on the actuator
Pilot valve remotely mounted/centralised
Pilot valve integrated in the actuator or process valve
