Flow passage control valve

A flow passage control valve connected to a pressure tank for housing an ion exchange resin bed, and a regenerant tank for storing regenerant of the ion exchange resin bed, the flow passage control valve comprising:

• a plurality of valves provided in a valve housing formed with set flow passages, wherein
• a camshaft for operating each of the valves is provided at an upper part of the valve housing along a right and left direction,
• the plurality of valves are arranged so as to be divided front and rear into a first valve group and a second valve group with the camshaft as a border therebetween,
• in the first valve group, a first water passage valve that is provided in a first water passage leading from a raw water inlet to the pressure tank, a second water passage valve that is provided in a second water passage leading from the pressure tank to a treated water outlet, and a bypass valve that is provided in a bypass passage for connecting the first water passage and the second water passage are laterally arranged side by side,
• a regeneration valve that is provided in a regenerant passage for allowing the regenerant of the ion exchange resin bed to pass is included in either the first valve group or the second valve group, and
• in the second valve group, remaining valves that are not included in the first valve group are laterally arranged side by side.
