ABOUT VALVES ONLY EUROPE
Water and Hydro System Valves for European Infrastructure
Water is Europe's most critical industrial and civil resource, and the infrastructure that treats, distributes, and manages it depends on valves that operate continuously, without failure, across service lives measured in decades. From municipal water treatment works and large-scale desalination plants to hydroelectric power stations, irrigation networks, and industrial process water systems, the requirements for valve performance in water service are demanding in their own distinct way combining corrosion resistance, tight shutoff, low maintenance, and long service life with the cost efficiency that large infrastructure projects require.
Valves Used for Hydro & Water Treatment:
- Gate Valve
- Ball valve
- Check ValveÂ
- Globe Valve
- Butterfly Valve
- Pressure Reducing ValvesÂ
- Air Release Valves
From Raw Water to Treated Supply: Treatment Plant Valves
Municipal and industrial water treatment plants handle raw water, chemically dosed process streams, and treated water across a complex network of pipelines, tanks, and process units. Our resilient-seated gate valves and double-eccentric butterfly valves in ductile iron and carbon steel provide reliable, economical isolation for large-diameter water treatment pipelines. For chemical dosing streams chlorine, coagulants, pH adjustment chemicals lined valve options in PTFE and rubber provide the chemical resistance required for long-term performance without body corrosion. Ball valves in 316 stainless are specified for instrument connections and sample points across the treatment process.
Harnessing Hydro: Penstock and Turbine Valve Engineering
Hydroelectric power generation places unique demands on valve engineering. Penstock inlet valves on large hydro schemes must handle enormous hydraulic forces, operate reliably after extended stationary periods, and provide fast-acting emergency closure when turbine protection requires it. Our butterfly valves and spherical valves in large diameters up to DN1200 and beyond for custom projects are engineered for hydro penstock service with hydraulic actuators that provide the operating force and speed required by turbine control systems. Flood protection gate valves for dam and sluice applications complete our offering for the hydropower sector.
From Field to Tap: Irrigation and Distribution Networks
Agricultural irrigation systems and regional water distribution networks cover vast geographic areas with piping ranging from small-bore distribution laterals to large transmission mains. Valve reliability across these networks is critical, a failed isolation valve in a rural transmission main may serve hundreds of users and require hours to reach for maintenance in remote locations. Our resilient-seated butterfly valves and gate valves for water distribution service are designed for low-maintenance, long-life performance in buried and above-ground installation, with epoxy-coated ductile iron construction providing corrosion protection across the range of soil conditions found across European agricultural regions.
The Infrastructure Partner Europe’s Water Projects Need
Water infrastructure projects whether greenfield treatment works, pipeline rehabilitation, or hydropower development require a valve supplier who understands both the technical requirements and the procurement realities of public-sector projects. Valvesonly Europe combines German engineering quality with the product range, stock availability, and competitive pricing that infrastructure projects demand. Our valves for water service meet EN 1074, EN 558, and WRAS requirements, with full documentation and third-party inspection available for projects requiring independent quality verification.
