Burkert宝德-Burkert隔膜阀技术参数
Type 0280 - 伺服控制的二位二通burkert隔膜阀描述：
burkert隔膜阀带有伺服隔膜和强制提升装置的先导式直通阀有两种类型，即在无流量时关闭或在无流量时打开。当作用方式 A 为关闭状态时，芯体会在弹簧力的作用下将先导式孔眼关闭。经由一个隔膜节流孔，在隔膜上方形成介质压力，进而关闭阀门。接通时，芯体先打开先导式孔眼。burkert隔膜上方的关闭压力被卸除，且阀门由介质压力打开。为了打开阀门，需的差压不能低于 0.5 bar。

Circuit Function
A 2/2-way valve, normally closed,
with 2-way pilot control
B 2/2-way valve, normally open,
with 2-way pilot control
Seal Materials/Fluids Handled/Temp.- Range
NBR Neutral fluids, e.g. compressed air, town gas,
water, hydraulic oil, oils and fat without additives
-10 to +90 °C
EPDM Oils and fat-free fluids, e.g. hot water
alkaline washing and bleaching lyes
-40 to+90 °C
FPM Hot air, oxygen, per-solutions, hot oils

For more detailed information please refer to resistance
chart (Leaflet-No. 1896009).
Max. ambient temperature +55 °C
Max. viscosity approx. 21 mm2/s
Response times opening approx. 50 ms
closing approx. 400 ms
The response times have been measured with water at a
working pressure of max. 6 bar. They depend upon
pressure and viscosity of the handled fluid.
