Electronical Controlled Lift Valve VF-LRV

This elevator valve with integral flow measuring system is used in frequency-controlled hydraulic drives. Based on the original LRV-1, combined with a frequency convertor acting directly on the motor/pump unit, it offers highest travel comfort, optimum heat dissipation and reduced noise emission.

VF-LRV technology is available only in combination with the power units of the Bucher Eco Line.
