Description
Available port sizes are ¾", 1 ½", 2" and 2 ½" pipe threads, depending on fl ow. EV4 eliminates high inrush currents and do not require
wye-delta switching. According to customers‘ elevator data, valves are factory adjusted, ready for operation and very simple to readjust
if desired. The L1000H Yaskawa drive combined with feedback systems that are designed to compensate elevator speed fl uctuations
regardless oil temperature and car load conditions.
Caution: The EV4 valve is to be used only together with Yaskawa L1000H inverter and not as standalone control valve.
EV4 valves include the following features essential for effi
cient installation and trouble free service:
The BLAIN EV4-vvvf program includes the widest range of vvvf solution off ered to the elevator industry for high performance
passenger elevators. Easy to install, EV4‘s are smooth, reliable and precise in operation throughout extreme load and tempera-
ture variations with inbuilt overload protection and diff erent energy saving modes. The EV4 system uses the control of L1000H
vvvf drive in the up travel, while down travel is managed by the EV4 valve itself. In this way, the EV4-vvvf solution off ers the most
cost-eff ective and energy-effi
cient solution.
