Strainer Manufacturer in Europe – Valvesonly Europe (Germany)
Valvesonly Europe manufactures industrial strainers in Germany for reliable filtration and protection of pumps, valves, turbines, meters, and process equipment. Our strainers are designed to remove solids, scale, rust, and other debris from pipelines, ensuring uninterrupted operation, extended equipment life, and reduced maintenance costs. Built to EN, DIN, and ASME standards, our strainers are available in cast iron, ductile iron, carbon steel, stainless steel, duplex, and high alloys to suit diverse industrial environments.
Function & Working
Strainers use perforated or mesh-lined screens to filter solid particles from liquid, gas, or steam pipelines. They are installed upstream of critical equipment, preventing blockages and minimizing wear. Filter elements are easily removable for cleaning or replacement. Options include simplex (single basket), duplex (twin basket with continuous operation), and self-cleaning strainers for uninterrupted duty in high-load systems.
