Products Details

All-welded pipeline ball valve is a kind of valve widely used in oil, gas, chemical, Marine, power and heating industries. It has the following features and advantages:

All-welded structure: All-welded pipeline ball valve adopts all-welded body structure, no external leakage point, improving the sealing and reliability of the valve.

Material selection: the main material of the valve can be carbon steel, stainless steel, etc., according to customer requirements and application conditions, different materials can be selected to adapt to different media and temperature ranges.

Design standards: The all-welded ball valve design conforms to a variety of domestic and foreign standards, such as API 6D, ASME B16.34, etc., to ensure the quality and performance of the valve.

Temperature range: Fully welded ball valves are suitable for a wide temperature range from -50°C to +280°C to meet the needs of different environmental conditions.

Sealing performance: PTFE seal ring and spring, adapt to pressure and temperature changes, to ensure that the valve in the use of no leakage.

Easy to operate: The all-welded ball valve can be driven by manual, worm gear, pneumatic, electric and other driving methods, easy to operate, easy to realize automatic control.

Easy maintenance: The valve stem seal is designed with a triple independent seal system that allows easy replacement of seals at full line pressure in either full open or full closed positions.

Emergency seal injection: As an option, all-welded ball valves can provide additional emergency seal injections for seat ring and stem seals.

Buried installation: Fully welded ball valves can be installed directly in the ground, without the need to establish high valve Wells, reducing engineering costs, while avoiding damage during valve operation.

Fire resistance: The design of the all-welded ball valve ensures that it meets the fire safety requirements of international standards such as API 6FA, API 607 and BS 6755 P2.
