1, Large flow capacity. The valve has excellent cutting performance. When fully open channel and pipe diameter is almost the same, fluid pressure loss is very small, so it is suitable to all kinds of liquid, gas, slurry and other fluid cut-off control.
2, Anti- electrostatic function. The pressure of the spring behind the anti-electrostatic steel ball promote the close contact between the inner wall of the groove and the ball, to transfer the friction electrostatic between valve ball and the valve seat to the stem. A middle opening sheet is specially made of the conductive material, which transfers the electrostatic to the valve body through close contact with the valve body and the valve stem.
3, Anti-leakage performance is good. The double butterfly shaped spring piece device design help the two pre-pressing pieces of butterfly shrapnel to have compensation effect when micro leakage appears in the stem and release the preload deformation to compress packing.
