product overview
y-type tie rod telescopic filter is a combination of y-type filter and expansion joint. it is mainly used for water supply and drainage pipes in high-rise buildings, multi-storey buildings or factories. it is usually installed in pressure reducing valves, pressure relief valves, fixed water level valves or other major equipment. the inlet end of the valve is easy to remove sundries or install and disassemble to ensure the normal use of valves or equipment.
structural features
1. strong stain resistance. the sewage is convenient; the circulation area is large. small pressure loss: simple structure, small size and light weight.
2. material of filter element. all made of stainless steel. strong corrosion resistance. long lasting.
3. filter density: 10-120 mesh, medium: steam, air, water, oil or customized according to user requirements.
4. features of telescopic type: stretched length, the maximum position can be moved 100mm. conducive to easy installation and improve work efficiency.
