The end of the valve is equipped with prefabricated grooves and is connected through grooved pipe joints, rubber sealing rings and bolts. The gate plate of the valve is entirely covered with high-performance elastic materials (such as EPDM, NBR). Achieve bidirectional bubble-level sealing to ensure zero leakage. When the handwheel is turned to open the valve, the valve stem will rotate accordingly and rise steadily upwards. When closed, the valve stem rotates in the opposite direction and descends.
