  • Description
    • PKS series is multiplex, pilot operated piston, conductive, and normally close (NC) 2/2 solenoid valve
    • Explosion-proof Protection Level: Ⅱ2 G Ex e mb ⅡC T4 Gb
    • Waterproof Protection: IP67
    • Being suitable to operate frequently
    • Availability of fluid: water, air & light oil
 
  • Cautions
    • Minimum pressure to operate: over 0.5kgf-cm2
    • Before installation depressurize the piping system and clean internally.
    • For the protection of the equipment install a strainer or filter suitable for the service involved in the inlet side as close to the solenoid valve as possible.
    • Ambient temperature should be under 70ºC
    • Operating temperature should be under 60ºC
    • AC voltage tolerance: +/- 10%; DC voltage tolerance: +/- 1%
    • All standard solenoid valve MUST be mounted vertically upright.
    • Not suitable for fluid as below:
      • Liquid status when it is at high temperature; solid status when it is cool.
      • Corrosive fluid
      • Seawater
      • Viscosity over 20cst
