We perform guaranteed seal replacement, hydraulic unit maintenance, and body repairs of critical main valves in HEPP and industrial facilities.
As Tekmaksan Engineering, we provide professional services for the maintenance and repair of main valves (usually Butterfly and Spherical types), which act as the safety shield of hydroelectric power plants and large industrial pipelines. These valves ensure the safety of the facility by cutting off the water flow during turbine maintenance work or in emergencies; therefore, even the slightest leakage or opening-closing failure is unacceptable. Our company revises valves that have suffered corrosion over time, lost their sealing ability, or have problems with the hydraulic drive system, either on-site or in the workshop environment. In our service process, wear on the valve body and disc is removed with special welding and machining methods, sealing gaskets (seals) are renewed, and metal-to-metal contact surfaces are precisely lapped to ensure 100% sealing. In addition, the maintenance of the hydraulic pistons moving the valve, control of weight systems, and repair of by-pass lines are carried out meticulously. After all mechanical operations are completed, the valves are subjected to hydrostatic tests and operational function tests under high pressure. Tekmaksan Engineering guarantees the smooth operation of your main valves in times of crisis and the safety of your facility.
