Filter valve, also known as filter :: filter pretreatment device. Filter valve is the use of hydraulic control valves and sophisticated easy to plug the mechanical products must have the filter equipment. It is an indispensable device for transporting pipeline series of media and is usually installed on the inlet of equipment such as hydraulic control valve, pressure reducing valve, pressure relief valve and water level valve to eliminate the impurities in the medium and prevent the granular impurities from entering Channel, causing the wall plug to protect the equipment pipeline Fittings from wear and clogging.When cleaning, as long as the removable cartridge can be removed, re-loading after treatment, therefore, the use of maintenance is very convenient.
