A double-acting control valve on the tractor is necessary for this - an unbeatable combination in combination with the integrated locking block .When adjusting the hydraulic toplink, it is very important that the adjusted position is maintained even after a long period of time. This is hardly possible with top links without a locking block, as the tractor's control units do not lock so tightly. This top link is therefore equipped with a locking block. With this valve, the oil is enclosed in the cylinder by a check valve. Only when there is oil pressure from the tractor again does the valve open and the cylinder can be adjusted. The hydraulic top link is made of high-quality steel and features a high-strength steel piston, threaded gland with wear ring, polished chrome plated rod, and welded steel base ends. It is designed to withstand heavy applications and extreme weather conditions. The piston and rod seals ensure excellent sealing performance, preventing oil evaporation, air leakage, and piston blockage.
