Q647FLarge bore pneumatic ball valveUsage Instructions:

1.Ensure the pipeline and valves are flushed before operation.

2.The valve operation is completed by rotating the valve rod according to the input signal size of the actuator: clockwise rotation1/4Ring(900)At this point, the valve is shut off. Reverse rotation.1/4Loop(900)At that time, the valve opens.

3.When the directional arrow of the actuator is parallel to the pipeline, the valve is in the open position; when the directional arrow is perpendicular to the pipeline, the valve is in the closed position.

Q647FLarge Diameter Pneumatic Ball ValveStructural Features:

1Smooth opening and closing without friction. This feature completely solves the traditional...[wiki]Valve[/wiki]Sealing issues due to mutual friction between sealing surfaces.

2Upward-mounted structure. Valves installed on pipelines can be directly inspected and maintained online, effectively reducing downtime and lowering costs.

3Single valve seat design. Eliminates the issue of using safety affected by abnormal pressure increase of the medium in the valve cavity.

4Low-torque design. The valve rod with a special structural design can be easily opened and closed with just a small handwheel valve.

5The wedge seal structure ensures the valve is sealed by the mechanical force provided by the valve stem, pressing the ball wedge against the valve seat. This design maintains the valve's sealing integrity regardless of pressure differential changes in the pipeline, guaranteeing reliable sealing performance under various operating conditions.

6Self-cleaning structure on the sealing surface. When the sphere moves away from the valve seat, the fluid in the pipeline flows along the sealing surface of the sphere.360Uniform flow not only eliminates the local erosion of the valve seat by high-speed fluid, but also washes away the accumulated deposits on the sealing surface, achieving the purpose of self-cleaning.
