I have the Simplicity/Allis 9020/720 and the boom on the backhoe is drifting when I release the stick. It has 6 sticks to control everything. I want to swap out this old control valve. Anyone know what I should be "googling" to find a replacement? |

Or you could replace the spools with electrically operated then install a joystick for ease of control. With electric spools your dealing with wires from the joystick, keeps things neat and tidy. http://www.oemoffhighway.com/operator-cab/operator-interface/joysticks/operator-interface/product/10257375/danfoss-danfoss-power-solutions-formerly-sauerdanfoss-js7000-joystick" rel="nofollow - http://www.oemoffhighway.com/operator-cab/operator-interface/joysticks/operator-interface/product/10257375/danfoss-danfoss-power-solutions-formerly-sauerdanfoss-js7000-joystick   |

First off is the drift from valve body or a internally leaking cylinder - drift is generally when pressure is unequal between ends of piston and fluid on back side of movement direction - so a void or open flow no non pressure return side - bypass of packing is another thing ------------- Faith isn't a jump in the dark.
