Miniature Proportional Valves
Parker miniature proportional valves — Precision Fluidics VSO family and Lucifer EPP4 electronic pressure regulators. Current-controlled orifices for precise flow and pressure control in analytical, medical and industrial instruments.
Size: Miniature bodies; orifices 0,25-3,18 mm; PC-board, manifold-mount or G1/4 threaded (EPP4).
Temperature: 0 °C to +50 °C typical.
Application: Proportional flow control (VSO Mini, LowPro, MAX HP — flows to 200+ slpm) and electronic proportional pressure regulation 0-10 bar (Lucifer EPP4, 0-10 V or 4-20 mA command).
Media: Clean dry non-reactive or inert gases; EPP4 compressed air.
Pressure: VSO Mini low differential; VSO MAX HP to 8,3 bar (120 psi); EPP4 regulates 0-10 bar
