Control units massey ferguson

The version is a mobile control block with 2 additional control devices, a switching valve from the original hydraulics to the additional control device and an operating lever for the three-point hydraulics via the additional control device. Installation is carried out using a mounting plate on the hydraulic riser pipe. The two additional control devices can be used double-acting. The outer control spool can be switched from single-acting to double-acting.The functions of the additional control valve are:Lever No. 1, Switching valve from original hydraulics to additional control unit Lever up: normal tractor hydraulic Lever down: work control valveLever No. 2, actuation of the three-point hydraulics without control hydraulics when switching to the additional control unit with lever No. 1, position downLever No. 3, double-acting control deviceLever No. 4, double-acting control device can be switched to single-acting via the changeover tap on the side of the end plate. If the changeover tap is screwed onto the seat, the control slide can be used double-acting. If the changeover cock is turned out to the stop, the function of the control slide is switched to single-acting.The operating lever of the tractor hydraulics/power lift must be in the outer hydraulics position so that the function of the additional control unit is guaranteed. The scope of delivery includes:The screws for attaching to the hydraulic block are included. ~There is also a hose package with 4 hydraulic hoses and matching hollow screws, ~ 4 pieces of clutch sleeves with dust protection and a holder for the clutch sleeves for attaching to the differential housing included. ~

This control valve is a /4-way valve that is operated manually to control single-acting and double-acting cylinders as well as hydraulic motors. The control valve from AK- Regeltechnik was developed specifically for Fiatagri tractors with Kontak hydraulics. Due to the high liter output, up to 4 control valves can be flanged directly. Since the hole pattern is completely identical to Kontak/Parker, this valve can also be installed with original Kontak/Parker control valves. The valve is a four-position device. It can be converted from double-acting to single-acting and vice versa. The control valve is a slide-sealed valve that exhibits absolutely neutral fine control behavior and allows extremely low fit leakage even at higher pressures. The device has a locked safety limit switch in the LIFTING position. If you switch further via the LOWER position, you will reach a locked floating position. This can be returned to the NEUTRAL position manually at any time.
