    詳細信息
     

    應用范圍:
    它廣泛應用于船舶重工、測試設備、加熱設備、液壓設備等,工作溫度在300℃以上的導熱系統中。
    產品特點:
    閥芯均為不銹活塞式,活塞環用特殊耐溫、耐磨材料制作;活塞與金屬閥腔不產生直接摩擦,閥體安裝方向無限制;特制線圈,并采用散熱的結構方式,因此不易燒毀;長時間停止動作重新啟動,動作同樣靈敏;最低啟動壓力0.2MPa。
    主要技術參數:
    產品規格:
    DN0.5~DN200
    閥體材質:
    不銹鋼
    適用介質:
    油、蒸汽、腐蝕流體等
    溫度范圍:
    +300~+450℃
    防護性能:
    防潮、防爆(Exd IICT5)、防腐
    接線方式:
    接線座式;引線式;插頭式
    控制方式:
    常開、常閉
    電源電壓:
    DC24~127V; AC36~380V
    連接方式:
    內螺紋、法蘭(外螺紋和特殊接口可定做或加轉接頭)
    工作原理:
    常閉:當線圈通電時,先導閥芯吸合,先導孔打開,閥上卸壓,活塞靠下腔介質壓力推動,電磁閥打開;當線圈斷電時,先導閥芯靠彈簧復位,先導孔關閉,閥上腔由活塞節流孔增壓和復位彈簧的推力,閥關閉。

    Applications: 
    It is widely used in shipbuilding Heavy Industry, test equipment, heating equipment, hydraulic equipment, the working temperature above 300 ℃ thermal systems.
    Features: 
    Are stainless steel piston valve, piston ring with a special temperature, wear-resistant material; piston valve chamber with the metal does not have a direct friction, the valve mounting direction unlimited; special coil structure and way of using heat, it is not easy burned; long time to restart the stopped action, action as sensitive; minimum starting pressure 0.2MPa.
    Main technical parameters:
    Specifications:
    DN0.5~DN200
    Body material:
    Stainless Steel
    Medium:
    Oil, steam, corrosive fluids
    Temperature range:
    +300 ~ +450 ℃
    Protection performance:
    Moisture-proof, explosion-proof (Exd IICT5), anti-corrosion
    Wiring:
    Terminal Block Type; lead type; male
    Control:
    Normally open, normally closed
    Power supply voltage:
    DC24 ~ 127V; AC36 ~ 380V
    Connection:
    Thread, flange (male and special interfaces or add custom adapter)
    How it works: 
    NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve, piston push media pressure on the lower chamber, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole Close the valve on the throttle chamber pressurized by the piston return spring and thrust, the valve closed. 
    Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. When the coil power, the pilot valve by the spring return, pilot hole open, pressure relief valve on the chamber, medium pressure piston push the lower chamber, the electromagnetic valve is opened.
