feature

The top flange cast as a whole can be directly installed with various actuators
The rocker arm bridge shaped packing press cover compensates for the unbalanced force of the packing cover nut, reducing the possibility of valve stem packing leakage
Extended valve neck design allows for a 2-inch thick pipeline insulation layer
The flattened stem journal port inside the valve body allows the stem bearing to tightly adhere to the valve plate, providing maximum stem support, reducing wear, and extending service life
The conical pin of the valve plate is half inside the valve plate and half inside the valve stem. Tangential positioning allows the valve plate and valve stem to withstand compressive pressure rather than shear stress, which can avoid shearing
The valve plate limit and valve body are cast together, ensuring accurate positioning of the valve plate relative to the valve seat and extending the sealing life of the valve seat
K-LOK polymer, rubber valve seat, and fire safety valve seat are suitable for vacuum to full pressure differential range and achieve bi-directional tight shut-off. The achievable service life of valve seats made of various materials in different applications
