产品简介

工作原理:
常闭:当线圈通电时,电磁铁芯吸合,卸压孔打开,主活塞由介质压力推动,打开主阀口,介质流通。
   当线圈断电时,主阀口关闭,介质截止。
常开:当线圈通电时,电磁铁芯吸合,卸压孔关闭,主活塞由介质压力推动,关闭主阀口,介质截止。
   当线圈断电时,主阀口打开,介质流通。

工作原理:
常闭:当线圈通电时,电磁铁芯吸合,卸压孔打开,主活塞由介质压力推动,打开主阀口,介质流通。
   当线圈断电时,主阀口关闭,介质截止。
常开:当线圈通电时,电磁铁芯吸合,卸压孔关闭,主活塞由介质压力推动,关闭主阀口,介质截止。
   当线圈断电时,主阀口打开,介质流通。

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.
