GSA-93 Pump station for gate valve control


GSA-93 Pump station and stand-by block for gate valve hydraulic drive is used for normal and emergency control of gate valve hydraulic cylinders of CC machines ladles.

The pump station comprises three pump units (two spare and one operating), main and control reservoirs, hydropneumatic accumulators block and gas vessel.

Electrical power cabinet is used for operation and parameters control of pump station and hydraulic cylinders.

The station is operated at Magnitogorsk Iron & Steel Works.
