Basket strainers trap solids via a perforated or mesh-lined removable basket in Y-type, T-type or inline flanged bodies from DN15 to DN600. Ductile iron, WCB, SS304/316 or carbon steel with EPDM/NBR/PTFE seals give low pressure drop, high dirt-holding, easy basket pull-out and corrosion resistance. Bolted cover, drain plug, differential-pressure port optional; no actuator, flow-driven only. For water, oil, chemicals, paints, HVAC and pump suction protection under DIN/ANSI/JIS.
