品牌：RETZ/我們一直致力于流體控制領域的持續創新，始于2005……進口中壓電磁閥通常為活塞式結構,廣泛應用于吹瓶機械、空壓機、加濕設備、高溫高壓場合、中高溫熱水、導熱油、高溫蒸汽、飽和蒸汽及過熱蒸汽等需要高壓控制的系統中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
進口中壓電磁閥工作原理
working principle
當線圈（1）通電，動鐵芯（2）吸合，先導閥口（3）處于開啟狀態，使主閥塞（4）上腔降壓，主閥塞（4）因壓差開啟，介質流通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
當線圈（1）斷電，動鐵芯（2）靠彈簧復位，先導閥口（3）處于關閉狀態，使主閥塞（4）上腔升壓，將主閥塞（4）壓下，電磁閥關閉 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
此種高壓式結構電磁閥主要使用在高壓流體，它需要一定壓力才能正常工作This
high-pressure structure solenoid valve is mainly used in high-pressure fluids
and requires a certain amount of pressure to function properly
進口中壓電磁閥產品特點
Product Features
先導式結構，閥芯均為不銹鋼活塞，活塞環不會被介質中的雜質卡死，動密封性能高，壽命長 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
活塞與金屬閥腔不產生直接摩擦，閥體安裝方向無限制 There
is no direct friction between the piston and the metal valve chamber, and the
installation direction of the valve body is unrestricted
線圈不易燒毀，長時間停止動作重新啟動，動作同樣靈敏 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，使用壽命長達100萬次以上 Zero leakage,
with a service life of over 1 million times
