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.

Orbital Ball Valve | Floating Ball Valve

The ball of the ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure that the outlet end is sealed. The floating ball valve has a simple structure and good sealing performance, but the load of the sphere bearing the working medium is all transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the sphere medium. This structure is widely used in medium and low pressure ball valves.

Self-cleaning structure of orbital ball valve sealing surface

When the ball is tilted away from the valve seat, the fluid in the pipeline will pass evenly through 360° along the sealing surface of the ball. It not only eliminates the local washing of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.

Orbital Ball Valve | Elastic Ball Valve

The ball of the ball valve is elastic. Both the ball and the valve seat sealing ring are made of metal materials, and the sealing specific pressure is very large. The pressure of the medium itself cannot meet the sealing requirements, and external force must be applied. This valve is suitable for high temperature and high pressure media. The elastic sphere is made by opening an elastic groove on the lower end of the inner wall of the sphere to obtain elasticity. When closing the passage, use the wedge-shaped head of the valve stem to expand the ball and press the valve seat to seal. Loosen the wedge-shaped head before rotating the sphere, and the sphere will return to its original shape, so that there is a small gap between the sphere and the valve seat, which can reduce the friction of the sealing surface and the operating torque. .

Orbital ball valve product features

1. There is no friction when opening and closing. This function completely solves the problem of traditional valve sealing due to the mutual influence between the sealing surfaces
2. The top-mounted structure can directly check and copy the door installed on the pipeline online to successfully reduce device parking and reduce production costs
3. Single valve seat design. Eliminates the problem that the medium in the valve cavity affects the safety of use due to abnormal pressure increase
4. Low torque design. The valve stem with a special structure design can be easily opened and closed with only a small handwheel valve
5. Wedge-shaped sealing structure. The valve is sealed by pressing the ball wedge to the valve seat by the mechanical force provided by the valve shaft. The sealing performance of the valve is not affected by changes in pipeline pressure difference, 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 will pass evenly through 360° along the sealing surface of the ball. It not only eliminates the local scouring of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.

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
