Orbit Ball Valve/rising Stem Ball Valve

Product Description

Orbit ball valve in the pipeline is mainly used for emergency cut off, distribution and change the flow direction of the medium. This type ball valve is a new type of valve widely used in recent years.

1, Orbit ball valve try to with frictionless operation, when the valve is opened, the stem is first lifted to disengage the ball from the seat, and then the stem drives the ball to the open position. When close the valves , THE STEM TURNS THE BALLwill not TOUCH THE SEAT, THEN THE STEM DROPS TO COMPRESS THE BALL AGAINST THE SEAT.

2, Orbit ball valve adopts the ball valve with fixed shaft structure, to ensure the valve switch fast, low torque, to open and close easily.

3, The orbit valve body structure with top mounted design to ensure that the replacement and maintenance of the internal parts of the valve can be repaired online by removing the valve bonnet, no  need to remove the valve from the pipeline.

4, To ensure that the orbit ball valve has a long-term, continuous tight sealing characteristics. The seal between the valve ball and the seat does not depend on the pressure of the medium , to ensure the seal of the valve will not affected by the medium pressure fluctuations.

5, Ball sealing face and seat sealing face with frictionless design to ensure the long life of the valve seal body. During the opening and closing process of the valve  avoid the damage caused by mutual friction to the sealing surface of the valve ball

6. The orbit valve seat is embedded in the valve body by cold pressure mechanical interference so the valve seat is not installed by welding, thread or adhesion.

7, Cut off ball valve seat with no scour design. When opening AND CLOSING the valve, the valve instantly fully open or fully closed, so that the valve in the switching process without high-speed fluid local erosion valve seat sealing surface, will improve the sealing life of the valve.

8, The sealing surface of the valve ball surface with nickel-based carbide, Haste alloy or other alloys. The minimum thickness of the surfacing is not less than 1.5mm to ensure the valve's tightness and long sealing life under the  demanding working conditions.

9, The orbit valve has double-way sealing ability, can withstand double-way pressure difference.

10. The fire resistance design of valves complies with API 6FA and API 607 standards. All valves with fire safe.

11, The orbit valve stem through the stem nut, valve bonnet valve body, ball core formed a circuit continuous conduction, to achieve the anti static effect.

12, In order to improve the reliability, safety and sealing ability. The orbit ball valve does not depend on the valve seat spring to achieve.

13, The position of the stem and the valve ball control by the stem guide pin and stem cut off., to ensure the stability of the valve operation, the stem guide pin is double, and the stem guide pin can be removed and replaced from outside.

14, The hand wheel or bearing is fixed with bolts or nuts, will not with elastic clamping ring.

15, The installation size of the valve is consistent with the existing valve, can be have  good interchangeability.
