KONAN YS202 Zero-differential Pressure Pilot-acting 2-port Solenoid Valves Normally Open Type

Product Made In Japan
Manufacturer: KONAN ELECTRIC
Model: YS202

YS202 have 2-port solenoid valves are hanging diaphragm valve that start operation with zero differential pressure. The valves are applicable for pressures from –100 kPa to 0.96 MPa.
