Looking to mount a grapple on my 1991 330, currently it is plumbed with a live line from the main hydraulic pressure feeding the spool bank and has a return tied into the return side of spool bank. I was hoping to add a 1" electric over hydraulic valve to control the grapple opening and closing with a switch on the joystick. Would this be a closed system? Is there any concerns to controlling a grapple in this way? This would also be used for a thumb and bucket combo so i would like to add a pressure relief valve so as to not bend the cylinder if the bucket came up against it. Thanks, Dave
