Proportional flow regulator P82 series

for airfor gasfor liquids

Motorised proportional flow valve with low power consumption and resistance to contamination. Throttle setting by wear- resistant control drives made of oxide ceramic. Throttling occurs with drip-tight zero shut-off but no gas tightness. Media: compressed air, vacuum or liquids up to viscosity of 40 mm²/s Hysteresis: ± 4% Operation: DC, synchronous or stepping motor with standard voltage of 24 V DC or AC ±10% residual ripple and IP 54. All motors fulfil standards EN50.081-1, EN50.082-2 and 89/336/EEC. DC_motor_(15/24): Motor with feedback potentiometer for servo-amplifier. Resistor 1kΩ ± 20 %, control e.g. by servo-amplifier. Only part of potentiometer range is used. Voltage for potentiometer 12 V, max. 10 mA. DC_motor_(50/51): With integrated position controller. Setpoint input using jumpers = 0...10 V, 0/4...20 mA. Input resistance 200 kΩ at voltage signal, 500 Ω at current signal. Stepper_motor_(38): Bipolar, by means of SAA1042A (Motorola) with drop resistance of 44 Ω per phase at a driver (full-step). operating voltage of 24 V ± 5%. 2028 steps for 90° control disc turn, 200 Hz nominal step frequency. Body: brass Control_discs: oxide ceramic Elastomer: NBR/Buna-N, optionally FKM or EPDM
