1. Packing pad can be added, that can reduce the torque when valve opening and closing
2. Metal-wrapped flexible graphite gasket for 150LB, metal-wound gasket for 300LB and 600LB, metal gasket for 900LB and above, or 600LB according to customer’s requirement.
3. The elastic wedge type disc can compensate the surface distortion of the valve seat and the deformation of the valve body caused by the pipeline pressure.
4. The stem design has a tapered upper sealing surface, which is sealed with the back seat on the bonnet when valve be fully opened.
5. The strength of connection between stem and wedge exceeds the strength of stem screw root.
6, The sealing surface of seat is spray welded with STL 6 cobalt-based hard alloy, the seat can be fixed by welding, or be threaded as customer’ s requirement.
Structure: Bolted bonnet, outside screwed stem and yoke, threaded back seat. rising stem, flexible wedge gate.
