進口帶指揮器自力式壓力調節閥
進口帶指揮器自力式壓力調節閥
美國WORK進口帶指揮器操作型自力式壓力調節閥無需外加能源,利用被調介質自身能量為動力源,自動控制閥門介質流量,使閥后壓力保持恒定的壓力穩定裝置。現已廣泛應用于連續送氣的天然氣采輸,城市煤氣以及儲罐氮封系統和冶金、石油、化工等工業生產部門。
產品特點
1、控制精度高,可比一般ZZY型直接操作型調壓閥高一倍左右。調節壓差比大(如閥前0.8MPa、閥后0.001MPa)特別適合微壓氣體控制。
2、壓力設定在指揮器上實現,因而方便、快捷、省力省時可在運行狀態下連續設定。
3、帶指揮器操作型自力式壓力調節閥采用指揮器操作,減壓比可達100:1,減壓效果好,控制精度高;
