What CMO Valves does
CMO Valves (legal entity: CMO VALVES TECHNOLOGY S.L.) is a privately held Spanish industrial valve designer and manufacturer founded in February 1993 and headquartered in Altzo/Tolosa, Gipuzkoa. The company produces knife gate valves (more than 15 series variants covering abrasive slurries, high-pressure mining, dry solids, pulp processing, and toxic media), butterfly valves (Series ME for hydroelectric forced conduits, Series 27A for water and firefighting), wall-mounted gates, channel and radial gates, check valves, control valves, and dampers. Manufacturing is concentrated across two Spanish facilities totaling roughly 6,000 m² of production space plus 400 m² of testing capacity, with quality systems certified to ISO 9001 since 1997.
The business model is B2B industrial manufacturing. Revenue is generated through one-time sales of engineered and standard valves, with pricing quote-based in euros and excluding VAT, shipping, and duties. CMO sells directly through wholly-owned subsidiaries in France (Dardilly), China (Chengdu), and South Africa (Alrode); through a B2B e-commerce platform (Valves Online) targeting customers without negotiated pricing agreements; and via regional channel partners including Bonomi UK for the UK water sector and Komplekt Service LLC for Russia. Distribution reach extends to more than 70 countries via delegated agents and resellers.
The customer base is diversified across water and wastewater utilities (with WRAS approval supporting UK AMP8 participation), mining, pulp and paper, hydroelectric power generation, chemical processing, and combustion gas systems. Recent strategic activity centers on entering the UK water-utility market under AMP8 regulatory spend (August 2025 partnership with Bonomi UK), maintaining a long-tenured ISO 9001 certification, and operating in 8-language website and catalog formats to support the global sales network. The company is privately held, independently owned, and has no disclosed institutional investors, M&A activity, or funding rounds in the source material.
