The BLAIN EV program includes the widest range of options offered to the elevator industry for high performance passenger service. Easy to install, EV‘s are smooth, reliable and precise in operation throughout extreme load and temperature variations.
Available port sizes are ¾”, 1½”, 2″ and 2½” pipe threads, depending on flow. EV‘s start on less than minimum load and can be used for across the line or wye-delta starting. According to customers’ information, valves are factory adjusted ready for operation and very simple to readjust if so desired. The patented up levelling system combined with compensated pilot control ensure stability of elevator operation and accuracy of stopping independent of wide temperature variations.
EV valves include the following features essential to efficient installation and trouble free service:
| · Simple Responsive Adjustment | · Self-Cleaning Pilot Line Filters |
| · Temperature and Pressure Compensation | · Self-Cleaning Main Line Filter (Z-T) |
| · Solenoid with Connecting Cables | · Built-in Turbulence Suppressors |
