进口超高压电磁阀│德国莱克LIK品牌

应用范围：
它广泛应用于航天、船舶重工、石油化工、测试设备、清洗设备、加湿设备、液压设备等，工作压力在100MPa以上的管道系统中。

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，阀体安装方向无限制；专制线圈，不易烧毁；长时间停用，动作同样灵敏；zui低启动压力1.0MPa。

主要技术参数：

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。

规格尺寸：

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:
It is widely used in aerospace, shipbuilding Heavy Industry, petrochemical, test equipment, cleaning equipment, humidification equipment, hydraulic equipment, the work of more than 100MPa pressure pipeline 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 mounting direction unlimited; authoritarian coil, easily burned ; for a long time disabled, the same movement sensitive; minimum starting pressure 1.0MPa.

Main technical parameters:

How it works:
NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole closed throttle valve chamber pressurized 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 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.

Size:

Note: The outlet pressure is greater than the inlet pressure, the media will pass anti-wizard. Can be installed or custom built non-return valve function of the valve
