| What is the market situation of general cast steel ball valves? The price of cast steel ball valve is about 300-1700 yuan. The casting steel ball valve opening and closing member (sphere) is driven by the valve stem and rotates around the axis of the valve stem. It is mainly used to cut off or turn on the medium in the pipeline, and can also be used for fluid regulation and control. The hard seal V-shaped ball valve has a strong shear between the V-shaped ball core and the metal valve seat of the hardfacing alloy. Shear force, especially suitable for media containing fibers, tiny solid particles. Cast steel ball valves are generally divided into handle cast steel ball valves, pneumatic cast steel ball valves, electric cast steel ball valves, cast iron ball valves, stainless steel ball valves, all copper ball valves. Cast steel ball valve is characterized by its compact structure, easy operation and maintenance, suitable for general working media such as water, solvent, acid and natural gas, and also suitable for medium with harsh working conditions, such as oxygen peroxide, methane and ethylene. The ball valve body may be integral or combined. The price of cast steel ball valves is generally around 300 yuan. Cast steel ball valves range in price from 300 to 1000. Q11F, PN16~PN63 one-piece internal thread ball valves are suitable for PN1.0~4.0MPa, working temperature -29～180°C (sealing ring is reinforced PTFE) Or in the various pipelines of -29 ~ 300 ° C (the sealing ring is the para-polyphenylene), used to cut off or turn on the medium in the pipeline, using different materials, which can be applied to water, steam, oil, Nitric acid, acetic acid and other media. |
