The CKD WR Series water regulator reduces and stabilizes water pressure supplied to equipment. A diaphragm and spring mechanism maintains a set downstream pressure as supply conditions change. It is used for cooling water lines, washing equipment and process water supply where constant pressure protects downstream devices.
