ZS series zero differential valves
ZS series zero differential valves
Basically speaking, ZS valves has similar properties like UW series valves. 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, N.C and N.O. type. But ZS valve has both thread connecting and flange connecting, while UW valve only has the former connecting way, and the coil connecting way for ZS valve is with DIN connector while for UW is with flying leads……With different seals, this series solenoid valves could be used for many conditions, especially air and water system.
