武漢市同泰冶金工裝備有限責任公司是德國羅普閥門在武漢的總代理。 ROPO是德國著名的氣動、電動控制閥的專業(yè)制造廠家。ROPO主要生產氣動執(zhí)行器、電動執(zhí)行器、球閥、蝶閥、電動/氣動（單座，雙座，三通，套筒）調節(jié)閥，電/氣閥門定位器等。 ROPO自立式壓力調節(jié)閥無需外加能源，利用被調介質自身能源為動力源，引入執(zhí)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(wěn)定。具有動作靈敏，密封性好，壓力設定點波動小等優(yōu)點，廣泛應用于氣體、液體及蒸汽介質減壓穩(wěn)壓或泄壓穩(wěn)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(jié)約了能源。 ◇ 壓力分段范圍細且互相交叉，調節(jié)精度高。 ◇ 壓力設定值在運行期間可連續(xù)設定。 ◇ 對閥后壓力調節(jié)，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(zhí)行機構檢測精度高、動作靈敏。 ◇ 采用壓力平衡機構，使調節(jié)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, and differential pressure control. They are suitable for all those applications where deviations of the controlled variable from the adjusted set point are acceptable and the 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, water and heat suppliers.Since self-operated regulators are very reliable in fulfilling their switching and control 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 controlEasy to installAlso suitable as safety equipment
