Tightening torques of screws, bolts and nuts on the table below are especially specified.
The 3-point hydraulic circuit has a relief valve to restrict the maximum pressure in its circuit. This is a guide piston relief valve with damper, a direct acting relief valve suitable for relatively high pressure and capacity, and constructed so as to prevent chattering and other unstableness associated with direct acting relief valves. As shown… Read More »
