ZECO floating ball valve is divided into a full bore floating ball valve and reduced bore floating ball valve. Normally, the size is less than 6 inches. It is used to cut off or connect the medium in the pipeline. Our ball valve for sale is strictly designed according to API 608, testing according to ASME B16.34.
The valve can be widely used in papermaking, petrochemical, chemical industry, metallurgy, electric power, environmental protection, petroleum, light industry, and other industries. The valve stem adopts the built-in type, PTFE (or reinforced graphite) thrust pad structure prevents the valve rod from blowing out due to the pressure in the pipeline, and PTFE (or reinforced graphite) material reduces the opening and closing torque of the valve, making the operation more labor-saving. The floating ball valve and trunnion ball valve are fireproof and static proof design. We have already got an API 607 certificate, selling out more than 30 countries in the oil and gas industry.
ZECO trunnion mounted ball valve is divided into full bore trunnion mounted ball valve and reduced bore trunnion mounted ball valve. The trunnion mounted ball valve is simple in structure, small in volume and light in weight. The trunnion mounted ball valve is equipped with a floating valve seat. The valve seat moves under the medium pressure so that the sealing ring is tightly pressed on the ball to ensure the sealing. Bearings are usually installed on the upper and lower shafts of the ball, with small operating torque, suitable for large sizes. Maintenance is convenient, ball valve structure is simple, the sealing ring is generally movable, disassembly and replacement are more convenient. When the valve is fully open or closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes through, the valve sealing surface will not be eroded. And grease injection holes and purge holes are usually installed on the valve body to increase the tightness of the valve body with seat, as well as pipe cleaning.
