Bellow seal single-seated control valve has features of simple structure、top-guided、 S-shape passageway、high adjusting precision and cost-effective. Bellow sealed top bonnet can eliminate any potential leakage from the stem. Anti-rotation design can prevent the damage of the bellow caused by the torque generating from adjusting the valve in the assembling process. Because of self deformation and excellent anti-aging capability of the bellow, it can totally avoid the packing aging and temperature sensitive problems existing in traditional valves.
