KONAN NB/NC202 2-port Solenoid Valves For Nuclear Power Plants Normally Open

Product Made In Japan
Manufacturer: KONAN ELECTRIC
Model: NB/NC202

N20 series 2-port solenoid valves for nuclear power plants are pilot-type valves incorporating a hanging diaphragm that enables operation at zero differential pressure.
Applicable pressure ranges from -100 KPa to 1.37MPa, and brass or stainless steel bodies can be selected for NC application for control of various fluids.

■Applicable fluid： Air / Inert gas
■Valve type : NB/NC201（Normally closed type）　NB/NC202（Normally open type）
■Operation type : Pilot (operates with no differential pressure)
■Port size：Rc3/8 , Rc1/2 , Rc3/4
