[Basic Information]
Oil seal plug (X47W) opening and closing member is a perforated cylinder, cylinder and stem around the axis of rotation perpendicular to the channel, so as to achieve the purpose of opening and closing channels. Oil seal plug valves are mainly used for opening and closing the pipeline and equipment media. Oil seal plug valve for nominal pressure PN10, operating temperature -29 ~ 100 ℃ of urban construction, chemical, metallurgical, petroleum, pharmaceutical, food, beverage, environmental protection industry and other conditions of the pipeline, cut off or connect the pipeline medium .

[Valve Features]
1, plug valves for regular operation, opening and closing fast, lightweight.
2, plug valve fluid resistance is small.
3, plug valve structure is simple, the relative size of small, light weight, easy maintenance.
4, good sealing performance.
5, regardless of the installation direction, the flow of media can be arbitrary.
6, no vibration, noise.
[Adaptation conditions]
According to the structural characteristics of the plug valve and the design can achieve the function, can be selected according to the following principles.
① for the distribution of media and change the flow direction of the medium, the working temperature is not higher than 300 ℃, the nominal pressure PN ≤ 1.6MPa, the nominal diameter of not more than 300mm, the proposed selection of multi-channel plug valve.
② milk, fruit juice, beer and other food businesses and pharmaceutical companies and other equipment and pipelines, the proposed selection of austenitic stainless steel, tight conical plug valves.
③ oil field exploitation, natural gas field extraction, pipeline transportation branch, refining and cleaning equipment, the nominal pressure level is not greater than Class300, nominal diameter of not more than 300mm, the proposed selection of oil-sealed conical plug valves.
④ Oilfield exploitation, natural gas extraction, pipeline transportation branch, refining and cleaning equipment, the nominal pressure level is not greater than Class7500, the nominal diameter of not more than 900mm, the working temperature is not higher than 340 ℃, the proposed selection of oil-sealed conical plug valves.
⑤ in large chemical industry, containing corrosive media pipes and equipment, the requirements of the opening or closing speed of the occasion, for the nitric acid-based media can choose Teflon sleeve sealing conical plug valve; for the Acetic acid based medium, optional Cr18Ni12Mo2Ti stainless steel Teflon sleeve seal conical plug valve.
⑥ in the gas, natural gas, HVAC piping and equipment, the nominal diameter of not more than 200mm, should use filler-type conical plug valves.
