德國BURKERT兩位兩通電動比例閥簡介

The valve features a linear stepper motor as actuator. The integrated electronics simplify the process integration;
additional actuation modules are not necessary.
直接作用式比例閥型號 3280 適用于在密封式
或開放式調(diào)節(jié)回路中計量液體和氣體。
集成式電子裝置簡化了流程體化，

 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)
型號 3280 有比例閥標準款、帶集成式位置調(diào)節(jié)儀的規(guī)格
以及帶集成式過程調(diào)節(jié)器的規(guī)格三種可選。
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,
閥門通過線性步進電機驅動。
