Changing solenoid valve from normally open to normally closed

avinashsootre

hey all,

i have bought rotex 20201 solenoid valve which is normally open and i wanted to change it to normally closed. Actually out of 3 ports, 1 port is made dummy to make it normally open. So can we change the dummy to other port to make it normally closed solenoid valve? Please do help me out with this.

 

Thanks in advance

  • Hi Avinash,

    You can try plugging the top hole and opening the one that is currently capped. Keep in mind these valves have polarity and if you hook them up reversed they will bleed fluid past the valve once the pressure exceeds the compression strength of the internal spring.
