Technical details Temperature range 0°C ... +50°C Medium Filtered, oil-free and dried compressed air according to ISO 8573-1:2010, Class 7:2:4, instrument air, free of aggressive additives. Alternatively the pressure dew point must be at least 10°C below lowest occurring ambient temperature. Materials Body: Al (anodized), plastic, seals: NBR, inner parts: Al, steel and brass With an increasing input signal, the solenoid valve SV1 (air supply) is switched ON while at the same time the solenoid valve SV2 (air exhaust) remains closed. Air is supplied to the pilot chamber. The pressure in the pilot chamber increases and is applied to the upper side of the membrane. The valve which is connected to the membrane opens, and air flows towards the valve outlet. The outlet pressure is monitored by a pressure sensor which transmits a corresponding electrical signal to the control circuit. The control circuit adjusts the valve so that the outlet pressure is proportional to the input pressure. The pressure sensor continually controls the outlet pressure and keeps it proportional to the inlet pressure. 2 1 ? = pressure inlet 2 ? = outlet 3 ?= exhaust 4 ?= exhaust 1 3 4 SV 1 SV 2 82-EPV-1 Display Input signal Output signal Control circuit Valve Diaphragm Pilot chamber Pressure sensor 2 3 1 4 SV 1 SV 2 82-EPV-2 82-EPV-3 Display Input signal Output signal Control circuit Valve Pilot chamber Diaphragm Pressure sensor Function 02 Subject?to?change Function valves > proportional air regulator Series 82-EPV 82-EPV-*-*-*-*-F*-** Accessories without accessories 0C without bracket with cable connector, straight, 3m 0L without bracket with cable connector, right angle, 3m C0 with flat bracket without cable connector L0 with L-type bracket without cable connector CC with flat bracket with cable connector, straight, 3m CL with flat bracket with cable connector, right angle, 3m LC with L-type bracket with cable connector, straight, 3m LL with L-type bracket with cable connector, right angle, 3m Connection F1 G1/8 (only type 1) F2 G1/4 F3 G3/8 (only type 2 and 3) F4 G1/2 (only type 3) Output signal 1 1 ... 5 V DC 2 switch, NPN output 3 switch, PNP output 4 4 ... 20 mA DC Order code Series Type / Nominal size 1 2 mm 2 7 mm 3 11 mm Output range 1 0,05 ... 1 bar 3 0,05 ... 5 bar 5 0,05 ... 9 bar Input signal 0 4 ... 20 mA DC 3 0 ... 10 V DC
