The filter valve is also called a filter: a device for performing filtration pretreatment. Filter valves are filtration equipment that must be available with hydraulic control valves and precision, easily clogged mechanical products. It is an indispensable device for the pipeline series of conveying medium. It is usually installed at the inlet end of equipment such as hydraulic control valve, pressure reducing valve, pressure relief valve and fixed water level valve to eliminate impurities in the medium and prevent particulate impurities from entering. The passages cause wall plugs to protect the fittings on the equipment pipes from abrasion and clogging. When cleaning is required, the detachable filter cartridges can be taken out and reloaded after handling, so that the maintenance is extremely convenient.
