Product Description

Fully Welded ball valves with integral welded valve bodies can effectively avoid external leakage.

Welded ball valve is widely used in various fields, its superior quality and high performance stability is ordinary cast steel ball valve can not reach, all-welded ball valve service life is far greater than cast steel ball valve, all-welded ball valve is widely used in city gas, city heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other types of pipeline equipment.

Welded ball valves are generally available in blue, yellow, grey, black and other colours. Transmission methods include handle, worm gear, pneumatic, electric, etc.

• Trunnion mounted ball;
• Spring-loaded seat rings;
• Metallic or soft seals;  
• Double Block and Bleed"-version;
• Full or reduced bore;
• Flanged, welded or threaded connections;  
• Blow-out proof shaft;
• Shaft seals replaceable under full pressure in open and closed position;
• No static charging;
• Maintenance-free bearings;

Trunnion ball valve manufacturer designs their trunnion ball valve to work in a way similar to a floating ball valve. The working principle of a trunnion ball valve involves rotating the ball to control fluid or gas flow. When the actuator sends a signal to the stem, it rotates the ball by 90 degrees, opening or closing the valve. The seat ensures that the ball stays in place during rotation.

The injection system acts as a partial seal to prevent leakage when it occurs. To start the oil flow in a trunnion ball valve, the actuator on the valve is rotated 90 degrees, usually clockwise. The actuator is connected to the valve stem, which is linked to the ball. The rotation of the actuator moves the stem and the ball connected to it. This will result in an unrestricted flow of the substance in the pipe, and reduced pressure in the pipeline. This will restrict flow of the substances in the pipeline.
