EV4

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.

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:

Simple Responsive Adjustment

Temperature and Pressure Compensations

B44

Pressure Gauge and Shut Off Cock

Self Closing Manual Lowering

Self Cleaning Pilot Line Filters
