 Ambient temperature - 10 to + 60 °C Viscosity Max. 600 mm²/s (cSt) Power supply 24 V DC ± 10 % (max. residual ripple 10 %)
Power consumption < 1 W in holding position max. 8 W (DN2 − 6) resp. max. 12 W (DN8 & 10, as well as high-pressure versions)
型号 3280 有比例阀标准款、带集成式位置调节仪的规格
以及带集成式过程调节器的规格叁种可选。
The motor’s power consumption to hold a speci? c opening position of the valve is zero.
This key feature can reduce the energy consumption of a plant dramatically and thus make it more e?  cient.
Type 3280 is available as standard ON/OFF or proportional valve,
阀门通过线性步进电机驱动。
