Electronically controlled lift valve

All LRV-valves by Bucher dispose of an integrated Hall-sensor - or feedback sensor - to measure and regulate their flow-rates electronically.

This technology has been under constant development for 25 years and offers absolutely unequalled travel comfort, even under extreme conditions.

• LRV-1
  The original electronically controlled lift valve for passenger and freight elevators with integrated flow-rate measuring system (Hall-sensor).
• VF-LRV
  Based on the original LRV-1, combined with a frequency convertor acting directly on the motor/pump unit, this drive offers even higher travel comfort, optimum heat dissipation and reduced noise emission.
• C-LRV 
  This simplified and standardized version of the orginial LRV-1 offers all the advantages of electronically controlled travel comfort at a very smart price.
