Morpower 3 way valve

[gauthib12]

Hello,

I have a general question about valve blocks..I have the Morpower block which is very well made (imo), rotary type it worked fine when I first got it...now I am having problems with the center port..the servo turns the valve rotates but the cylinder wont move?..I switched ports cylinder is fine so I am at a loss...I took it apart and nothing unusual, the center valve does seem to leak with the pump on..ugh..anyone have any thoughts? I did email Morpower just waiting for a response..

Thanks
