Proportional Pressure Controls (PPC)
FEMA makes a full line of proportional pressure controls from 6.9 bar to 345 bar (100 psig. to 5000 psig) in manifold and pipe mount configurations. The frictionless 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.
