HVOF coated ball valve

As the global energy structure accelerates toward renewables, pumped storage power stations have become the most mature and economically viable large-scale energy storage solution. In response, Geko Valve & Control, a German manufacturer of industrial valves and control systems, has made early moves in the pumped storage power station sector – with a strong focus on electric ball valves for hydropower plants.     Founded in 1956 (with roots tracing back to 1946), Geko entered the Chinese market in 2005 and established a production base and sales center in Changzhou. The company has already demonstrated its reliability in critical hydropower applications, supplying valves for China's national flagship project – the Baihetan Hydropower Plant.   Tailored Solution for Pumped Storage: GKQ0350-GKV225 DN150 PN25     For pumped storage applications requiring frequent start-stop cycles, high differential pressure, bidirectional flow, and ultra-low fugitive emissions, Geko introduces the GKQ0350-GKV225 electric ball valve – featuring DN150 nominal diameter and PN25 pressure rating. This model is specifically engineered to meet the stringent demands of pumped storage power stations.   Key technologies include HVOF spraying (rocket spray process, hardness up to HRC 66–72) for superior erosion and corrosion resistance, backed by TÜV ISO15848 low-leakage certification and ISO 10497 fire safety compliance.   Looking Ahead   Geko expects strong growth over the next five years as China's 14th Five-Year Plan and subsequent initiatives roll out dozens of new pumped storage projects. The company will continue to advance its valve and control technologies for pumped storage power station systems, contributing to the next-generation power grid.   Beyond hydropower, Geko also serves high-precision and demanding industries including hydrogen energy, LNG, green methanol, nuclear power (e.g., the "Linglong One" mini-reactor), semiconductors, aerospace, and biopharmaceuticals – reinforcing its position as a forward-looking industrial valve specialist.
