[basic information]
high-pressure forged steel ball valve is mainly used for long-distance pipeline transportation of oil and natural gas and urban gas pipeline system. due to the unique characteristics of the long-distance pipeline valve, the design has fully taken into account its ability to withstand pipeline stress, as well as safety, weather resistance, long-term use of reliable sealing, structural design is a unique stunt company. there are manual mode of operation - worm gear drive, pneumatic, electric, gas \ liquid linkage, electric \ liquid linkage, as well as various types of special control.
[valve features]
1, all parts of this product are forgings.
2 , the use of the next-type valve stem, set the inverted seal structure to ensure that the packing at a reliable seal and prevent the valve stem prolapse.
3 , with embedded valve seat. o-ring behind the seat set to ensure that the media do not leak.
[adaptations]
ball valve is an important industrial automation and control system executive body, remote control can meet the needs of computer-controlled long-distance; now in the petrochemical industry, gas equipment, nuclear industry, power equipment, environmental water treatment, hvac, iron and steel metallurgy, industrial kiln, canning equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, biopharmaceuticals, food machinery, textile printing and dyeing, papermaking and other industries are widely used, but also the national defense construction, construction of science and technology of choice.
