Features & Benefits

SF41 is an indispensable filtering device in pipeline systems for conveying media. It is usually installed at the inlet end of pressure reducing valves, relief valves, constant water level valves, or other equipment to remove impurities from the medium and protect the normal use of valves and equipment. The Y-shaped filter has the characteristics of advanced structure, low resistance, and convenient discharge.
