Product Overview
Pipeline ball valves are suitable for pipelines in various working conditions such as petroleum, chemical, and thermal power plants with working temperatures of -28 to 300°C, to cut off or connect the medium. Main applicable media include: petroleum, purified natural gas, sour natural gas, coal gas, water, and coal slurry. The driving device operation modes include: manual, worm gear drive, pneumatic, electric, gas-hydraulic linkage, etc.

Product Features
The pipeline ball valve (trunnion mounted) is a bidirectional valve with unrestricted flow direction. The middle flange is connected by studs. Both upper and lower stems are equipped with sliding bearings to reduce friction, making operation labor-saving and smooth. Under normal circumstances: at low pressure, the seat seal relies on the spring pre-tightening force to make the seat closely fit the ball to achieve sealing; at high pressure, a piston effect is formed on the seat, and under the action of the upstream medium pressure, the seat is pressed tightly against the ball to achieve sealing. The product is widely used in process control systems to achieve open or close functions.
