工作原理：
常閉：當線圈通電時，電磁鐵芯吸合，卸壓孔打開，主活塞由介質壓力推動，打開主閥口，介質流通。
當線圈斷電時，主閥口關閉，介質截止。

Applications:
It is widely used in metallurgy, petrochemical, pharmaceutical, food, medical, textile and other fields. For small-caliber, low-pressure pipeline system.
Features:
Small size, attractive appearance; coils directly start the spool, the valve is closed by a spring reset; zero-voltage start-up; leakage is zero; authoritarian coil, easily burned; unlimited installation direction of the body.
Main technical parameters:
| Specifications: | DN8 ~ DN300 |
| Body material: | Cast iron body, cast steel body, stainless steel （not cast iron body and steel body fluids in corrosion on） |
| Medium: | Water, gas, oil, steam, gas, corrosive fluids |
| Temperature range: | -20 ~ +200 ℃ |
| Media Viscosity: | Less than 50C St （greater than the time to be customized） |
| Protection performance: | Waterproof, explosion-proof （Exd IICT5）, anti-corrosion |
| Wiring: | Terminal Block Type; lead type; male |
| Control: | NC |
| Power supply voltage: | DC24 ~ 127V; AC36 ~ 380V |
| Connection: | Thread, flange （male and special interfaces or add custom adapter） |
How it works:
NC: When the coil is energized, the electromagnetic force pilot hole first open the main valve piston chamber pressure drops, pressure and electromagnetic force to take advantage of the pilot spool pickup linked the main piston, valve port open; power failure, by a spring Reset pilot hole off the main piston chamber pressurization, push the main piston moves down, the valve closed. Always open and always closed the opposite.
