High-grade Forged Steel Ball Valve Unique Features
- Sep 30, 2017 -

High-grade forged steel ball valve has a unique automatic pressure relief function, when the valve medium pressure exceeds the spring preload, the exit side of the valve seat back from the ball, to achieve automatic pressure relief effect, the valve seat automatically reset, Water, solvents, acids and natural gas and other general working medium, but also for poor working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene, in various industries have been widely used.

High-grade forged steel ball valve closing the ball around the center of the valve body to achieve the rotation to open, close a valve, the seal embedded in the stainless steel seat, the metal valve seat at the end of the spring, when the sealing surface wear or burn , Under the action of the spring to push the valve seat and the ball to form a metal seal.

High-grade forged steel ball valve is mainly used for cutting off or connected to the medium in the pipeline, can also be used for fluid regulation and control, including hard-sealed V-ball valve V-shaped core and surfacing carbide alloy metal seat Has a strong shear force, especially for fiber, micro-solid particles and other media.

The multi-ball valve in the pipeline not only can be flexible control of the media confluence, diversion, and flow of the switch, but also can turn off any channel and the other two channels connected. High-grade forged steel ball valves should be installed horizontally in the pipe. High-grade forged steel ball valves have a 90 degree rotation action, the swivel body is a sphere, with a circular through hole or passage through its axis.

The ball valve is mainly used in the pipeline to cut, distribute and change the direction of flow of the media, it only needs to rotate 90 degrees of operation and a small turning torque can be closed tight. High-pound forged steel ball valves are best suited for switching and shut-off valves, but recent developments have designed the ball valve to allow it to have throttle and flow control, such as V-ball valves.

High-grade forged steel ball valve is characterized by its own compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical surface is often closed, not easily eroded by the media, easy to operate and maintenance, suitable for water, And natural gas and other general working medium, but also for poor working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene, in various industries have been widely used. High-grade forged steel ball valve body can be a whole, it can be a combination of.
