FEMA makes a full line of proportional pressure controls from 100 pisg. – 5000 psig. The friction-less suspended armature allows for longer life and fewer reliability problems due to system contamination. These valves have many applications from relief valve piloting to molding pressure control.
FEMA custom designs and develops products to specific customer needs. The following specifications are intended as examples. Please contact us with your application to learn more about our capabilities.
