Hydraulic gear motor with thermovalve
KRACHT

The thermovalve is a pre-controlled pressure relief valve with temperature-dependent pressure control and is mounted on the KRACHT KM gear motor in the place of the existing cover plate. Motor + TKM = fan motor There are two different types: a) Pressure and temperature control TKM 1 D ... and b) Quantity, pressure and temperature control TKM 1 M ... The basic principle of both variants is that the pressure setting of the valve automatically changes dependent on the temperature, via a built-in flexible material element, and thus controls the motor speed. The pressure control for
a) contains a pure pressure control, while the quantity and pressure control for b), in addition to the pressure control, also contains a permanently set quantity control. In addition to the actual temperature-controlled pressure setting, a mechanical maximum pressure control, set in the factory, and a recharging valve are fitted as a non-return valve. To enable further consumption units to be installed in the fan motor cycle, there is also a type with external oil discharge. The “internal” oil discharge model must be arranged when the order is placed, as a subsequent conversion can only be carried out in the factory.
