ГСД hydraulic distributors

ГСД hydraulic distributors are intended for manual and automated control of hydraulic cylinders of mining machines and other types of hydraulic advancers inside highly gaseous and/or dusty coal mines.

Distributors are used in control systems for mechanized and automated roof support units, sinking and heading machines, cutter-loaders as well as a variety of other mechanized and automated control systems for assemblies and machinery.

Modifications:

  • ГСД16-24Э, ГСД3-24Э — hydraulic distributor with electromagnetic drive and backup manual drive;
  • ГСД20-01 — hydraulic in cartridge form.
