进口高温电磁阀--德国莱克(LIK)品牌

应用范围：
它广泛应用于船舶重工、测试设备、加热设备、液压设备等，工作温度在300℃以上的导热系统中。

产品特点：
阀芯均为不锈活塞式，活塞环用特殊耐温、耐磨材料制作；活塞与金属阀腔不产生直接摩擦，阀体安装方向无限制；特制线圈，并采用散热的结构方式，因此不易烧毁；长时间停止动作重新启动，动作同样灵敏；*低启动压力0.2MPa。

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，阀上腔由活塞节流孔增压和复位弹簧的推力，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：

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 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:

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.

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
