Wuzhong Valve Packing

For more detailed information, you will need to communicate directly with the manufacturer.

In addition to the A-series packing, there are various other packing series used in the valve industry; for example, flexible graphite packing: it is corrosion-resistant, heat-resistant, and flexible, making it highly suitable for use in valves under high temperature and pressure conditions. Metal fillers: such as stainless steel and brass, are suitable for applications that require high mechanical strength and wear resistance. Woven fillers: such as hemp-core woven fillers, which exhibit excellent wear resistance and chemical stability. Methods for selecting packing When choosing valve packing, the following factors need to be considered: medium properties: including the acidity or alkalinity of the medium, its corrosiveness, concentration, temperature, etc. For highly corrosive media, corrosion-resistant and chemically stable packing should be selected. Operating environment: includes factors such as temperature, pressure, and humidity of the operating environment. For example, valves used at low temperatures should be equipped with gaskets suitable for such low-temperature environments. Sealing requirement: Select a packing with appropriate sealing performance based on the usage requirements of the valve. Wear resistance: For media that are viscous or contain a high amount of particles, it is necessary to choose fillers with good wear resistance. Thermal and electrical conductivity: Valves generate heat during use, so the packing also needs to have certain thermal conductivity. For valves that require grounding, the packing should also be conductive.
