Electrically-operated valve EPR series

servo-drivenpressure-controlfor compressed air

Pneumatic proportional control valves - Series EPR Proportional valves, series EPR, are used in the field of pneumatics (compressed air) and allow the adjustment of the output pressure by means of an electrical signal. Depending on the measured pressure, these valves emit an electrical output signal, the so-called "feedback signal". Available in G1/8", G1/4" and G1/2" sizes, these valves feature a display that indicates the regulated pressure, but also facilitates configuration with an easily accessible user display. These pneumatic proportional control valves have an aluminium body, techno-polymer heads, a stainless steel spring and an NBR seal. Operating pressure: maximum control pressure + 1 bar Maximum pressure: 10 bar for models with adjustment range: 0÷5 bar and 0÷9 bar - 2 bar for models with adjustment range: 0÷1 bar Voltage tolerance: ± 10%. Medium: filtered, non-lubricated air or continuously lubricated compressed air Connection: G1/8", G1/4" - G1/2" - Pressure gauge (port): G1/8" - Flow rate at Pa=6 bar and Flow rate with Pa=6 bar and Δp=1: G1/8" : 290 Nl/min, G1/4" : 1440 Nl/min G1/2" : 4800 Nl:min Electrical connector: M12A 4 PIN Working temperature: between 0 °C and +50 °C Voltage: 24 V Materials: aluminium - body; stainless steel - spring; techno-polymer heads NBR seal Industry Industrial pneumatics Industrial automation Compressed air ✔ Sensitivity: ≤ ± 0.5% F.S. ✔ Linearity: ≤ ± 1.0% F.S. ✔ Repeatability ≤ ± 0.5 F.S. ✔ Hysteresis ≤ 0.5% F.S.
