Forged steel gate valve
Product Introduction of Forged Steel Manual Threaded Gate Valve
forged steel gate valve is suitable for various pipes of Class150 ~ Class2500, 1/2″ ~ 2″, used to cut off or connect the medium in the pipeline. Selecting different materials, forged steel gate valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc.
forged steel gate valves generally use flexible graphite packing. According to user requirements, PTFE packing, flexible graphite packing with various metal wires or composite packing can also be used. The surface area of the stuffing box in contact with the filler has a good finish Ra 3.2μm. After the contact between the valve stem and the filler is finished, it is subjected to roller extrusion processing to achieve a higher surface finish (Ra 0.8μm) and denseness, which can ensure Reliable sealing at the stem of the forged steel gate valve.
