武汉市同泰冶金工艺装备有限责任公司

武汉市同泰冶金工艺装备有限责任公司是德国罗普阀门在武汉的总代理。ROPO是德国著名的气动、电动控制阀的专业制造厂家。ROPO主要生产气动执行器、电动执行器、球阀、蝶阀、电动/气动（单座，双座，三通，套筒）调节阀，电/气阀门定位器等。
ROPO自立式压力调节阀无需外加能源，利用被调介质自身能源为动力源，引入执行机构控制阀芯位置，改变两端的压差和流量，使阀前（或阀后）压力稳定。具有动作灵敏，密封性好，压力设定点波动小等优点，广泛应用于气体、液体及蒸汽介质减压稳压或泄压稳压的自动控制。
◇ 无需外加能源，能在无电无气的场所工作，既方便又节约了能源。
◇ 压力分段范围细且互相交叉，调节精度高。
◇ 压力设定值在运行期间可连续设定。
◇ 对阀后压力调节，阀前压力和阀后压力之比可为10：1-10：8。
◇ 橡胶膜片式检测，执行机构检测精度高、动作灵敏。
◇ 采用压力平衡机构，使调节阀反应灵敏、控制精确。
◇ 维护量小，介质受控。

ROPO Self-operated pressure control valve
ROPO self-operated pressure control valve do not need power from outside, it use medium itself as power to change the pressure difference and flow.
More details please ask for our instruction.
ROPO hard seal double eccentric high performance series wafer butterfly valve, adopt double eccentric muti-layer metal seal structure, polished precise disc seal joint with three-view eccentric seal, it can bear high temperature, high pressure, permit mote on the medium, longer life.
Adopt double eccentric structure, almost no friction between disc and seat.
The material for seal is harden alloy, it is more wearable
It has both metal hard seal advantage and flexible seal advantage
Seal property won’t be effected by high temperature medium or low temperature medium
Four end connection styles all could be available
