screwed ball valve Description
Screwed ball valve is a rotary valve with a ball as the opening and closing part. It can cut off or circulate the pipeline medium by rotating 90°. The connection method with the pipeline is threaded (internal thread or external thread). The core components include valve body, ball, valve seat and sealing materials (such as polytetrafluoroethylene). Some high-pressure models use ceramic materials to improve wear resistance.
Classification and type
By connection method Internal thread ball valve: The valve body has threads inside, which is suitable for small-diameter low-pressure pipelines. External thread ball valve: The valve body has external threads at both ends, which is easy to install and has reliable sealing. By functional structure Three-way threaded ball valve: It has three channels for medium diversion, confluence or flow direction switching, which is commonly used in laboratories or complex pipeline systems. High-pressure internal thread ball valve: The working pressure can reach 80MPa, and it has automatic pressure relief function, which is suitable for high-pressure scenes such as chemical industry, oil and gas extraction

screwed ball valve
Features
Performance advantages:
Compact structure, light weight, flexible operation and fast opening and closing;
Good sealing, using polytetrafluoroethylene or ceramic materials, suitable for vacuum and corrosive media;
High-pressure models support automatic pressure relief, and the valve seat is separated from the ball under abnormal pressure to ensure safety.
Special design:
Ceramic ball valves have excellent wear resistance and are suitable for high-wear conditions;
External threaded ball valves have precise thread design, firm connection and support a variety of specifications (such as 2 points, 3 points, etc.).
Applications
Industrial scenarios: Chemical, petroleum, and natural gas pipeline systems, used for medium cutoff or flow control; People's livelihood areas: Household water supply, laboratory fluid distribution, scenarios that require fast opening and closing or flow regulation; Special industries: Electricity (cooling water system), food and medicine (sanitary medium control).
