Highlight: Cast Steel Globe Valve
Product introduction:
The cast steel globe valve adopts a rising stem bracket type
structure with bolted bonnet connection, featuring a rotating
lifting stem and handwheel. The design of the valve body and bonnet
undergoes strict calculations to ensure excellent strength,
rigidity, and flow capacity. The bonnet is equipped with a backseat
seal, which enhances the reliability of the packing seal in the
fully open position and facilitates packing replacement.Suitable
for pipelines in various working conditions such as petroleum,
chemical, metallurgy, electric power, papermaking, pharmaceutical,
food, water treatment, petrochemical, and thermal power plants, it
is used to cut off or connect pipeline media.
