Introduction of imported medium and low pressure solenoid valve products:
German de The medium and low pressure solenoid valve imported from Locke adopts the pilot type structure. The valve cores are all stainless steel pistons. The piston ring will not be stuck by impurities in the medium. It has high dynamic sealing performance and long service life. There is no direct friction between the piston and the metal valve chamber. The installation direction of the valve body is unlimited. The autocratic coil is not easy to burn. It is also sensitive when it stops for a long time. It has zero leakage and a long service life of 1 million yuan More than three times.
 

進(jìn)口中低壓電磁閥工作原理：

常閉：當(dāng)線圈通電時(shí)，先導(dǎo)閥芯吸合，先導(dǎo)孔打開，閥上腔卸壓，活塞靠下腔介質(zhì)壓力推動(dòng)，電磁閥打開。
當(dāng)線圈斷電時(shí)，先導(dǎo)閥芯靠彈簧復(fù)位，先導(dǎo)孔關(guān)閉，閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力，電磁閥關(guān)閉。

Working principle of imported medium and low pressure solenoid valve:
Normally closed: when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.
When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.
