P8

Description:
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.
All motors fulfil standards EN 61000-6-3, EN 61000-6 and 2014/30/EU.

DC_motor_(15/24):
Motor with feedback potentiometer for servo-amplifier. Resistor 1kΩ ± 20 %, control e.g. by servoamplifier.
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.

Temperature_range: 10 °C to 90 °C / 14 °F to 194 °F
Protection_class: IP 54

Body: brass
Control_discs: oxide ceramic
Elastomer: NBR/Buna-N, optionally FKM or EPDM

Mounting_position: vertical upwards ± 60 °C
