Marine Ball Valves
Marine ball valves consist of a ball with a round through hole for opening and closing. The ball moves with the stem to achieve opening and closing. In order to open and close the channel, the opening and closing parts of the ball valve rotate around an axis perpendicular to the channel.
Application of Marine Ball Valve
Three-way ball valves can be flexibly cut off, distributed, and changed in flow direction in pipelines to cut off or adjust the use of the medium. Ball valves have a spherical sealing surface, therefore they are not easily washed by the medium, are easy to operate, and have a compact and simple design.
While the cock body rotates 90 degrees to lift, the difference is that it is a sphere with a circular channel passing through its axis. If the ball rotates 90 degrees, all the spherical surfaces should be present at the entry and exit, thus cutting off the flow.
The marine ball valve can be tightly closed with just a 90-degree rotation and a small amount of torque. As a result of the valve’s completely equal internal cavity, the medium flows smoothly and there is little resistance along the flow path. Traditionally, ball valves have been used for direct opening and closing, but recent developments have allowed them to be throttled and controlled.
Features of Marine Grade Ball Valves
- Due to the alloy steel spray welding core and alloy steel surfacing sealing ring, the hard sealing ball valve in the switch will not produce too much wear.
- Hard sealing ball valves have good sealing performance because spools and sealing rings need to be ground to match until they are completely matched.
- Therefore, it performs well in terms of sealing. Switches are very light when the external force exceeds the pre tightening force because the sealing ring and valve core are tightly held together by a spring on the bottom of the sealing ring of the hard sealing ball valve.
- In addition to its compact structure, easy operation and maintenance, the ball valve is suitable for general working media, such as water, solvents, acids, and natural gases, as well as harsh working media, such as oxygen, hydrogen peroxide, methane and ethylene. Integrated or combined ball valve bodies are available.
