【簡單介紹】

ROPO自立式壓力調節閥無需外加能源，利用被調介質自身能源為動力源，引入執行機構控制閥芯位置，改變兩端的壓差和流量，使閥前（或閥后）壓力穩定。

【詳細說明】

ROPO自立式壓力調節閥無需外加能源，利用被調介質自身能源為動力源，引入執行機構控制閥芯位置，改變兩端的壓差和流量，使閥前（或閥后）壓力穩定。具有動作靈敏，密封性好，壓力設定點波動小等優點，廣泛應用于氣體、液體及蒸汽介質減壓穩壓或泄壓穩壓的自動控制。
    ◇無需外加能源，能在無電無氣的場所工作，既方便又節約了能源。
    ◇壓力分段范圍細且互相交叉，調節精度高。
    ◇壓力設定值在運行期間可連續設定。
    ◇對閥后壓力調節，閥前壓力和閥后壓力之比可為10：1-10：8。
    ◇橡膠膜片式檢測，執行機構檢測精度高、動作靈敏。
    ◇采用壓力平衡機構，使調節閥反應靈敏、控制精確。
    ◇維護量小，介質受控。

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
