                  [Valve features]

                  1, According to the use of temperature and medium of work using self lubrication material bushing, lubrication good, in the whole process of sealing, vice friction coefficient is small, plug body flexible operation, long service life.

                  2, The medium can flow in both directions, the installation direction unrestricted, online maintenance, more convenient to use.

                  3, Unique design, can prevent static electricity, safe fire prevention, use safety.

                  4, Good sealing performance.

                  5, No vibration, small noise.

                  [Adaptive condition]

                  According to the structural characteristics of the plug valve and the design can achieve the function, you can choose the following principles.

                  1, As for the distribution media and change the flow direction of medium, its temperature is not higher than 300℃, Nominal pressure  less than or equal to 1.6MPa,Nominal diameter less than or equal to 300mm, suggested the use of multiple plug valve.

                  2, Milk, juice, beer and other food enterprises and pharmaceutical factories and other equipment and pipes, it is recommended to use austenitic stainless steel system, compact conic cone plug valve.

                  3, In oil field exploitation, natural gas field exploitation, pipeline transportation branch pipe, refining and cleaning equipment, nominal pressure level is not more than Class300, nominal diameter is not more than 300mm, it is recommended to use oil seal type conical plug valve.

                  4, The exploitation of oil and natural gas production, pipeline transportation, refining and pipe cleaning equipment, nominal pressure level is not greater than Class7500, nominal size is not greater than 900mm, the temperature is not higher than 340℃, suggested the use of conical plug valve oil seal.

                  5, In large scale chemical industry, pipelines and equipment containing corrosive medium, required to open or close the faster the occasion, for nitrate based medium can be used Teflon sleeve conical plug valve seal; for acetic acid based medium, can choose Cr18Ni12Mo2Ti stainless steel Teflon sleeve conical plug valve seal.

                  6, In gas pipelines, natural gas, HVAC systems and equipment, nominal diameter is less than 200mm, should choose the packed type conical plug.
