Forged steel globe valve
Product Introduction of Forged Steel Globe Valve
Forged steel globe valve is suitable for various pipes of Class 150~Class 2500, 1/2″~2″, used to cut off or connect the medium in the pipeline. Selecting different materials, forged steel globe valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc.
Product Features of Forged Steel Globe Valve
Forged steel globe valves developed and manufactured by chenggao generally use flexible graphite packing. According to user requirements, PTFE packing, flexible graphite packing with various metal wires or composite fillers can also be used. The surface area of the stuffing box that is in contact with the packing has a good finish (Ra 3.2μm). After the contact part of the valve stem and the packing is finished, it is subjected to roller pressing to make the surface reach a higher finish (Ra 0.8μm) and denseness. This ensures a reliable seal at the valve stem. According to user requirements, a disc spring-loaded packing compression mechanism can be used to make the sealing of the packing more durable and reliable.
