This hydraulic elevator control valve from Blain is smooth, reliable, and precise in operation throughout extreme load and temperature variations. It starts on less than minimum load and can be used for across-the-line or wye-delta starting. This control valve is factory-adjusted, ready for operation, and very simple to readjust if so desired. The patented up-leveling system and compensated pilot control ensure stability of elevator operation and accuracy of stopping independent of wide temperature variations.
