burkert00239088电磁阀可以根据模拟信号(电流或者电压信号)的大小来调节流量大小。控制器burkert 8605是跟比例阀配套使用的,是将电流或者电压信号转换成PWM,信号。
burkert00239088电磁阀水流量计算:
Pressure drop kv value forliquids[m³/h]
kv value forgases[m³/h]Subcritical
Supercriticalp2 > 2p1p2 < 2p1= Qρ1000 Δp= Qρ1000 Δp= Q514N ρN T1p2 Δp= QN ρN
burkert00239088回路功能:
Valve control takes place through a PWM signal 1). The duty cycle of the PWM signal determines the coil current and hence the position of the plunger. Optionally the valve can also be driven with DC voltage.
