          \n

          Working Principle<\/h1>\n

          The valve utilizes quarter-turn operation to regulate or isolate flow.<\/p>\n

          Opening Cycle<\/h3>\n
            \n
          1. The actuator rotates the shaft.<\/li>\n
          2. The disc moves away from the seat.<\/li>\n
          3. Flow passage gradually opens.<\/li>\n
          4. Full flow is achieved at 90\u00b0 rotation.<\/li>\n<\/ol>\n

            Closing Cycle<\/h3>\n
              \n
            1. The disc rotates toward the seat.<\/li>\n
            2. Final seating creates sealing contact.<\/li>\n
            3. Flow is completely isolated.<\/li>\n<\/ol>\n

              The offset geometry reduces friction between sealing surfaces, minimizing wear and extending service life.<\/p>\n
