What is orbital ball valve

What is orbital ball valve

Orbital ball valve and gate valve are the same type of valve. The difference is that its closing part is a sphere. The sphere rotates around the center line of the valve body to achieve opening and closing. The ball valve head is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The ball valve is a new type of valve that has been widely used in recent years.

Ball valve is divided according to its channel position

Ball valves can be divided into straight-through type, three-way type and right-angle type according to their channel position. The latter two ball valves are used to distribute the medium and change the flow direction of the medium. The ball valve and the plug valve are the same type of valve. Only its closing part is a ball. The ball rotates around the center line of the valve body to achieve opening and closing.

Frequently Asked Question

Do you have any question?

Even though ball valves aren’t the best device to control flow, they are still commonly used because of their cost effectiveness. You can get away with using a ball valve in an application that doesn’t require precise adjustability and control.

ORBIT rising stem ball valve's unique tilt-and-turn design reduces seal rubbing and delivers reliable performance.Every ORBIT rising stem ball valve incorporates a proven tilt-and-turn operation that eliminates seal rubbing, which is the primary cause of valve failure.

When an ORBIT valve begins to open, the core tilts away from the seat and line flow passes uniformly around the core face. This eliminates the localized high-velocity flow that typically creates uneven seat wear in ordinary ball, gate and plug valves. The core then rotates to the fully open position
