Item no. 11200 11210
Sizes DN 10, DN 15 and DN 20 are also suitable for compression fittings. Function: Oventrop “Y” type strainers protect the pipework from harmful impurity, increase the service life of regulating and isolating valves and therefore prevent the premature breakdown of machines and appliances.
Due to the body being made of bronze and the wire basket of stainless chromium steel, Oventrop “Y” type strainers are corrosion-resistant. Depending on the degree of contamination of the fluid, the wire basket has to be cleaned from time to time. Oventrop “Y” type strainers have a high capacity of absorption. The surface of the wire basket corresponds to a multiple of the flow cross-section. Should a cleaning of the wire basket become necessary, this is easily done. Wire baskets for replacement are available for all dimensions.
The strainer can be either installed vertically or horizontally, but the direction of flow always has to be observed. To facilitate straining, the wire basket should be in a downward position. Two mesh sizes are available for the wire baskets: 0.6 mm = 100 meshes/cm² or 0.25 mm = 600 meshes/cm² for fine filtering. The wire baskets are exchangeable. DN 18
