PURPOSE: A pressure reducing valve for water supply is provided to improve the reliability of products and the operational stability by using a check valve and a filtering net. CONSTITUTION: A pressure reducing valve for water supply comprises a body(110), a lower cover(145), an upper cover(150), a diaphragm(160), a control axis(158), and a main packing(156). The body has an inlet(111), an outlet(112), an inner wall(116), an outlet connecting space(117), a connecting path(119), a water pressure control space(118), and a contact hole(120). The lower cover is combined in the lower part of the body and covers the outlet connecting space. The upper cover is combined on the top of the body. The diaphragm covers the water pressure control space. The control axis is connected in the operation of the diaphragm. The main packing controls the flow rate of the water flowing to the outlet connecting space through the flow path by controlling the water passage size.
