品牌：RETZ/我们一直致力于流体控制领域的持续创新，始于2005……进口中压电磁阀通常为活塞式结构,广泛应用于吹瓶机械、空压机、加湿设备、高温高压场合、中高温热水、导热油、高温蒸汽、饱和蒸汽及过热蒸汽等需要高压控制的系统中The Retz low and medium pressure solenoid valve is usually a piston type structure and is widely used in high-pressure control systems such as bottle blowing machinery, air compressors, humidification equipment, high-temperature and high-pressure occasions, medium and high temperature hot water, thermal oil, high-temperature steam, saturated steam, and superheated steam that require high-pressure control

进口中压电磁阀工作原理 working principle

当线圈（1）通电，动铁芯（2）吸合，先导阀口（3）处于开启状态，使主阀塞（4）上腔降压，主阀塞（4）因压差开启，介质流通When the coil (1) is energized, the moving iron core (2) is closed, and the pilot valve port (3) is in an open state, causing the upper chamber of the main valve plug (4) to decrease pressure. The main valve plug (4) opens due to the pressure difference, and the medium flows through

当线圈（1）断电，动铁芯（2）靠弹簧复位，先导阀口（3）处于关闭状态，使主阀塞（4）上腔升压，将主阀塞（4）压下，电磁阀关闭 When the coil (1) is powered off, the moving iron core (2) is reset by the spring, and the pilot valve port (3) is in a closed state, causing the upper chamber of the main valve plug (4) to increase pressure. The main valve plug (4) is pressed down, and the solenoid valve is closed

此种高压式结构电磁阀主要使用在高压流体，它需要一定压力才能正常工作This high-pressure structure solenoid valve is mainly used in high-pressure fluids and requires a certain amount of pressure to function properly

进口中压电磁阀产品特点 Product Features

先导式结构，阀芯均为不锈钢活塞，活塞环不会被介质中的杂质卡死，动密封性能高，寿命长 Pilot structure, valve core is made of stainless steel piston, piston ring will not be stuck by impurities in the medium, with high dynamic sealing performance and long service life

活塞与金属阀腔不产生直接摩擦，阀体安装方向无限制 There is no direct friction between the piston and the metal valve chamber, and the installation direction of the valve body is unrestricted

线圈不易烧毁，长时间停止动作重新启动，动作同样灵敏 The coil is not easy to burn out, and if it stops for a long time and restarts, the action is equally sensitive

泄漏量零，使用寿命长达100万次以上 Zero leakage, with a service life of over 1 million times
