Nickle Alloy Ball Valve Inconel 600 Floating Trunnion Elastic
Nickle Alloy Ball Valve: The opening and closing element of a ball valve is a ball with a circular passage that rotates around an axis perpendicular to the passage. The ball moves with the valve stem to open or close the passage. A ball valve can be tightly closed with a 90-degree rotation and a very small turning torque. Depending on the operating conditions, different actuating devices can be assembled to form ball valves with various control methods, such as electric ball valves, pneumatic ball valves, hydraulic ball valves, and so on.
Principle of ball valve structure:
- Ball valves are not restricted by the installation direction and the flow direction of the medium can be arbitrary. They have a low fluid resistance, and full-bore ball valves essentially have no flow resistance.
- The structure of the ball valve is simple, with a relatively small volume and light weight, making it easy to maintain.
- Tight and reliable. It has two sealing surfaces, and currently, the sealing surfaces of ball valves widely use various plastics, which provide good sealing and can achieve complete sealing. They have also been widely used in vacuum systems.
- Ball valves are suitable for frequent operation, with quick and easy opening and closing. They are convenient to operate, opening and closing rapidly, requiring only a 90° rotation from full open to full close, which is convenient for remote control.
- Easy maintenance, the structure of the ball valve is simple, and the sealing rings are usually movable, making them easy to dismantle and replace.
- Ball valves have good sealing performance. When fully open or closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium does not cause erosion of the valve sealing surface when passing through.
- A wide range of applications, with bore sizes ranging from a few millimeters to several meters, and they can be used from high vacuum to high pressure.
- Since ball valves have a wiping action during the opening and closing process, they can be used in media with suspended solid particles.
- Ball valves have low fluid resistance, no vibration, and low noise.
INCONEL ALLOY 600 (nickel-chromium-iron)(UNS N06600/W.Nr. 2.4816) is a standard engineering material for applications which require resistance to corrosion and heat. The alloy also has excellent mechanical properties and presents the desirable combination of high strength and good workability.
Characteristics:
The excellent mechanical properties of this alloy endow the material with high strength and good workability. It has good corrosion resistance, especially in alkaline environments, and can be used in low and high temperature environments.
Corrosion Resistance:
