Teflon Lined Plug Valve

A pressure balance type flip plug valve, consisting of a valve body, a cock, a stem and a filler, the cock is a conical valve plug over the upper end of the upper end, the cock is located in the inner cavity of the valve body, the stem driving cock rotates, the sealing surface of the cock is a cone, the stem and the cock are connected through the cross connector, and a cylinder between the stem and the cock is equipped with a cylinder. Spring or butterfly spring, the lower end of the valve body is fixed with a valve cover, the valve cover has a adjusting shaft, the lower end of the adjusting shaft is worn out of the valve cover and the top top cock, the lower end of the cock has a first check valve, the seal face of the cock is equipped with a seal oil tank, the valve body has a tank, the oil tank of the valve body is connected with the seal oil tank of the cock. The valve body is provided with an oil injection valve that is connected with the oil storage tank. The pressure balance type flip plug valve can be used under high temperature, high pressure and harsh conditions. It has the advantages of reliable sealing, small operating torque and long service life.

The KOSEN Teflon Lined Plug Valves (full lining type) and bushing stopcock (semi lining type). Plug valves are mostly used for cutting off medium flow, and also for medium distribution (three way stopcock). The fluorine lining valve is suitable for various concentrations of water, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids and strong oxidizing agents at -29~150 Degree C. FEP is also suitable for the use of various strong alkaline organic solvents and other corrosive gas and liquid medium.

The sealing property of the soft seal sleeve plug valve is realized through the sealing surface around the card sleeve. The unique 360 degree metal lip protection fixed card, the valve has no cavity to accumulate the medium, the metal lip in the rotary plug provides self cleaning effect, suitable for sticky and easy to scale the working conditions, two-way flow, the use of more convenient installation. The soft sealing cock valve is suitable for the nominal pressure CLASS150 to CLASS900, and the working temperature is -29 C ~ 180 Degree C, oil, chemical, pharmaceutical, chemical fertilizer, electric power industry and so on.

The KOSEN Bronze Plug Valves is widely used in oil field mining, transportation and scouring equipment. It is also widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC and general industry.
