Pneumatic Actuator Insulation Ball Valve

> Open and close without friction.The sealing problem of the traditional valve due to the friction between the sealing faces is completely solved.
> The top-loading structure can effectively reduce the parking of the device and reduce the cost.
> The single seat design eliminates the problem of safe use of the cavity medium in the valve due to abnormal boosting.
> Low torque design with wedge seal construction. The valve is powered by the valve stem and presses the ball wedge onto the seat to achieve a sealing effect. The sealing performance of the valve is guaranteed to be unaffected by the variation of the pipeline difference, and the sealing performance is reliably guaranteed under various working conditions.

> The sealing surface is self-cleaning.When the ball is tilted away from the valve seat, the fluid in the pipeline passes through the spherical sealing surface at 360°, which not only eliminates the high-speed fluid scouring on the valve seat, but also washes away the aggregate on the sealing surface to achieve self-cleaning.
