More about the company
Export sales department:

Based on the accumulated experience and continuous improvements, highly efficient control equipment has been created, which has a high degree of safety and reliability with a long service life:

  • pilot control units;
  • pilot-type control units with multi-hose;
  • control units of manual type;
  • limit pressure valves;
  • check and controlled check valves;
  • electrohydraulic control unit;
  • irrigation system.

The electro-hydraulic control system was developed jointly with Marco (Germany). On the basis of cartridge-and-block technology with a large throughput, it provides a high speed of movement of the support with full or partial automation of the process, a slight loss of pressure and ease of operation and maintenance:

  • Remote Control;
  • hydraulic block;
  • hydraulically operated check valves;
  • safety and check valves;
  • sensors for pressure, inclination, vibration, advance measurement, etc.;
  • filters;
  • system of cable connectors and hydraulic hoses;
  • network power supply;
  • explosion-proof РС.

All hydraulic control equipment is tested in a specialized laboratory, the conditions of which are as close as possible to operational ones.
