As countries around the world accelerate their transition toward renewable energy, hydropower stations remain a cornerstone for sustainable electricity generation. Hydropower projects require extremely reliable and high-performance flow-control components—especially large-diameter butterfly valves, high-pressure ball valves, air valves, and cast steel pipe fittings—to ensure operational safety and long-term stability.
In 2020, WEIZIDOM was entrusted with a major responsibility: supplying essential valve solutions for the construction of the KHOBI II Hydropower Project in Georgia. After analyzing the project’s engineering drawings, operating conditions, and hydropower system requirements, we provided a comprehensive set of valve solutions tailored specifically for the project. By 2022, we successfully completed the delivery of DN2400 double eccentric butterfly valves, ball valves, air valves, and cast steel fittings.
Today, KHOBI II stands as the largest hydropower station independently built by Georgia since the dissolution of the Soviet Union, and WEIZIDOM is honored to be part of this milestone.
The KHOBI II Hydropower Project is a landmark energy project located in western Georgia. Designed to improve the country’s power generation capacity and strengthen energy independence, this plant plays a strategic role in securing stable renewable power.
🔹 Largest hydropower project independently developed by Georgia post-Soviet era Official opening on October 31, 2024
🔹 Ceremony presided over by Georgian Prime Minister Irakli Kobakhidze
🔹 Annual power generation meets the electricity needs of approximately 50,000 households
🔹 Total contract value supplied by WEIZIDOM: USD 294,664.9
Such a massive infrastructure project requires extreme reliability in all hydraulic control equipment, which is why WEIZIDOM was chosen as a trusted supplier.
Hydropower stations demand valves that can withstand:

WEIZIDOM is proud to play a role in a project that benefits the country and thousands of people.
The Georgia KHOBI II Hydropower Project showcases WEIZIDOM’s engineering strength, manufacturing capacity, and reliability as a global industrial valve supplier. By providing DN2400 butterfly valves, ball valves, air valves, and cast steel fittings, WEIZIDOM has contributed to a historic renewable energy project that will benefit Georgia for decades.
WEIZIDOM will continue to support large-scale hydropower, water supply, and energy projects worldwide—delivering high-quality valves that ensure safe, reliable, and efficient operation.
Hydropower stations typically use large-diameter butterfly valves, ball valves, air valves, and check valves to regulate water flow, protect pipelines, and ensure safe turbine operation.
For the KHOBI II Hydropower Project in Georgia, WEIZIDOM supplied DN2400 double eccentric butterfly valves, ball valves, air valves, and cast steel fittings, all designed for high-pressure and continuous operation environments.
Double eccentric butterfly valves are essential for hydropower because they:
* Reduce friction and sealing wear
* Withstand high water pressure
* Provide stable flow control
* Operate reliably under large-diameter conditions
WEIZIDOM manufactured custom DN2400 units for KHOBI II, meeting international hydropower standards.
Producing a DN2400 butterfly valve requires:
* Advanced CNC machining
* High-strength cast steel
* Specialized coating technology
* Large-scale pressure testing equipment
Not all manufacturers can meet these requirements — WEIZIDOM is one of the few capable of producing such large valves with strict quality control.
Hydropower projects require complete documentation, including:
* Material certificates
* Pressure test reports
* Coating and lining reports
* 3D drawings
* QA/QC inspection forms
* Installation manuals
WEIZIDOM provides a full technical document package for all energy and water projects.
Air valves:
* Release trapped air
* Prevent vacuum collapse
* Reduce pressure surges
* Improve pipeline stability
They are essential for long-distance hydropower pipelines.
Because WEIZIDOM provides:
* High-quality industrial valves
* Customized engineering solutions
* Experience with 100+ countries
* Competitive factory pricing
* Reliable delivery timelines
* Proven performance in large energy projects
The KHOBI II project further strengthened international trust in WEIZIDOM.
