1. Adding packing pads to the packing group can reduce the torque required for valve opening and closing

2. Metal wrapped flexible graphite gasket is used for 150LB, metal wrapped gasket is used for 300LB and 600LB, metal gasket ring is used for 900LB and above, and 600LB can also be adjusted according to customer needs

3. Elastic wedge gate can compensate for valve seat surface distortion and valve body deformation caused by pipeline pressure

4. The valve stem design has a conical upper sealing surface, which is sealed with the sealing seat on the valve cover when the valve is fully opened

5. The connection strength between the valve stem and the gate exceeds the strength at the root of the valve stem thread

6. The STL. 6 cobalt based valve seat is installed using seal welding, or threaded seat rings can be used according to customer requirements
