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.

Technical Specifications

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. Other flows and pressures are available.
