The RLSY type telescopic filter is a combination of a Y-shaped filter and an expansion joint, mainly used for water supply and drainage piping in high-rise buildings, multi story buildings, or factories. It is usually installed at the inlet end of pressure reducing valves, relief valves, constant water level valves, or other major equipment to facilitate the removal of debris or installation and disassembly to ensure the normal use of valves or equipment.

Working Principle:
The RLSY telescopic filter is installed at the front end of each supporting valve in the inlet pipeline. When the medium in the pipeline first enters the filter, the medium enters the connected valve through the filter screen, while impurities remain in the filter barrel, so that various valves will not malfunction due to mechanical debris getting stuck in the sealing ring.
