KONAN YS201 Zero-differential Pressure Pilot-acting 2-port Solenoid Valves Normally Closed Type

Product Made In Japan
Manufacturer: KONAN ELECTRIC
Model: YS201

YS20 series 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.
