进口高压电磁阀德国汉威阀门（国际）有限公司—广州总代理产品特点：阀芯均为不锈钢活塞式，活塞环不会被介质中的杂质卡死，动密封性能高,寿命长；活塞与金属阀腔不产生直接摩擦，阀体安装向无限制；专制线圈，不易烧毁；长时间停止动作重新启动，动作同样灵敏；启动工作压力0.5MPa。主要技术参数：产品规格：DN0.5～DN200阀体材质：不锈钢适用介质：水、气、油、蒸汽、燃气、腐蚀流体等温度范围：-100～+200℃介质粘度：小于50C St(大于时需定制)防护性能：防水、防爆(Exd IICT5)、防腐接线方式：接线座式；引线式；插头式控制方式：常开、常闭电源电压：DC12～127V; AC36～380V连接方式：内螺纹、法兰(外螺纹和特殊接口可定做或加转接头)泄 漏 量：零工作原理：常闭：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开；当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。常开：当线圈通电时，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。当线圈断电时，先导阀芯靠弹簧复位，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。规格尺寸：产品代码HM810公称通径DN3、DN4、DN5、DN6、DN8适用压力0.5～70MPa接口螺纹G1/4G3/8阀体材质不锈钢、304、316等特殊功能可定制带手动、带止回功能注：出口端压力大于进口端压力，介质会反向导通。可安装止回阀或订制自带止回功能的阀。Applications: Widely used in aerospace, shipbuilding Heavy Industry, petrochemical, water, fire fighting equipment, food and medical equipment, cleaning equipment, landscape irrigation, humidification equipment, hydraulic equipment, testing equipment, water plant, the work pssure in the pipeline 6.4 --- 100MPa system.Features: Spool is stainless steel piston and piston rings will not be stuck impurities in the medium, dynamic sealing performance and long life; piston valve chamber with the metal does not produce direct friction, the valve installed to the limit; authoritarian coil, easily burned ; for a long time to restart the stopped action, action as sensitive; minimum start working pssure 0.5MPa.Main technical parameters: Specifications:DN0.5 DN200Body material:Stainless SteelMedium:Water, gas, oil, steam, gas, corrosive fluidsTemperature range:-100 +200 ℃Media Viscosity:Less than 50C St (greater than the time to be customized)Protection performance:Waterproof, explosion-proof (Exd IICT5), anti-corrosionWiring:Terminal Block Type; lead type; maleControl:Normally open, normally closedPower supply voltage:DC12 127V; AC36 380VConnection:Thread, flange (male and special interfacesoradd custom adapter)Leakage:ZeroHow it works: NC: When the coil is energized, the pilot spool pull the pilot hole to open, pssure relief valve on the chamber, the piston on the lower chamber medium pssure to promote, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole closed throttle valve chamber pssurized by the piston return spring and thrust, the electromagnetic valve is closed. Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pssurized 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, pssure relief valve on the chamber, the piston on the lower chamber medium pssure to promote the solenoid valve open.Size: Product CodeDM808DN1、DN3、DN4、DN5、DN6、DN8Apply pssure1 200 MPaInterface ThreadG1 / 4G3 / 8Body material304 stainless steel (316), etc.Special FeaturesCan be customized with a manual, with a return function)Note: The outlet pssure is greater than the inlet pssure, the media will pass anti-wizard. Can be installedorcustom built non-return valve function of the valve.进口高压电磁阀
