The widely use of Cut off ball valve

Cut off ball valve is a special kind of ball valve. It is composed by the pneumatic piston actuators and interlayer unitary cast body. Its special structure is that the seat is designed with rebound effect as the spring to form bi-directional flexible seat, ensuring the reliability of ball sealing. Meanwhile media pressure and the resilience of upstream end flexible structure enhance the seat sealing in downstream end.
Cut off ball valve is widely used in easy to crystallize and the viscous fluids. It can also meet the various needs of the insulation media occasions, to prevent crystallization of the medium and to ensure the efficient operation of the automatic control systems.
