VF-LRV the electronically controlled lift valve

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).

Advantages at a glace

• Travel characteristics independent of load and temperature (viscosity) with wide range of operating temperature
• Highest travel comfort up to 1 m/s
• 120 Travels per hour without cooling
• Low energy consumption (no cooler needed)
• Savings in machine-room ventilation
• Lower oil temperature resulting in less wear and tear of hydraulic parts
• Shorter and unvarying travel times
• Up to 10 dBA noise reduction in the machine room

Available versions

• VF-LRV 350-1 and VF-LRV 700-1
• All versions including: digital electronic card Delcon, power supply NTA-2, frequency invertor (VVVF), power unit with oil-submersed motor/pump unit
