Lift valve
max. 1 000 l/min, 70 bar | VF-LRV BUCHER Hydraulics

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 Economy Line (Saturn ALPHA and Orion ALPHA).
