ZS-O Series Valve
ZS Series valves have similar function as 2W series valves. It is also one of the most popular 2/2 solenoid valve. ZS series solenoid valves also start working at zero differential pressure and this valve also enjoys wide range sizes for threads from 1/8” to 2”, including stainless steel body, brass body. Normal close and normal open is optional. But there are two points that ZS is different from 2W valves. The first one is the connecting type, while ZS valve has flange connecting way besides thread connecting. The other is about the coil. ZS valve’s coil is DIN type.
