1 PC Cast Steel Floating Ball Valve

Products Description

The 1 PC cast steel floating ball valve can rotate around the centerline of the valve body to open and close. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. It is compact, lightweight, and simple to install and maintain. The high-quality materials of different parts ensure a long service life, with tens of thousands of opening and shutting operations under its belt.

Structural Features

This 1 PC cast steel floating ball valve has the following features:

1. Open and close without friction. This function completely solves the problem that the conventional valve affects the sealing due to the friction between the sealing faces.

2. Top-loading structure. The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce the parking of the device and reduce the cost.

3. Single seat design. It eliminates the problem that the cavity medium in the valve affects the safety of use due to abnormal boosting.

4. Low torque design. The specially designed valve stem can be easily opened and closed with a small handle valve.

5. Wedge seal structure. The valve is mechanically supported by the valve stem, and the ball wedge is pressed onto the valve seat to seal so that the sealing property of the valve is not affected by the change in the pressure difference of the pipeline, and the sealing performance is reliably guaranteed under various working conditions.

6. Self-cleaning structure of the sealing surface. 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 accumulation on the sealing surface to achieve self-cleaning. 

Application

This 1 PC cast steel floating ball valve has some unique advantages unique to its own structure, such as the switch without friction, the seal is not easy to wear, and the opening and closing torque are small. This reduces the size of the actuators that are supplied. With multi-turn electric actuators, the medium can be adjusted and tightly closed. It is widely used in the conditions of strict cutting off of water supply and drainage in petrochemical cities.
