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 regulators are available for temperature, pressure, flow,differential pressure control. They are suitable for all those applications where deviations of the controlled variable from the adjusted set point are acceptablethe set point remains constant over a long time - often during the entire useful life.
Self-operated regulators are especially suitable for applications that would otherwise require high investment due to the auxiliary energy supply system additionally required by other equipment. Therefore, self-operated regulators are frequently used in the wide-ranging networks of gas, waterheat suppliers.
Since self-operated regulators are very reliable in fulfilling their switchingcontrol functions, even or especially when the energy supply fails, they are ideally suited as safety equipment. Type tested devices designed according to the applicable regulations can be used in many fields of application and, at the same time, they have a good price/performance ratio compared to other solutions.
Constant set point – fixed set point control
Easy to install
Also suitable as safety equipment
