API Plug Valve

     CHAODA group专业研制生产API Plug Valve等 valve products, CHAODA生产的API Plug Valve适用于公称压力CLASS150-CLASS1500,工作温度为-29-180℃的石油,化工,制药,化肥,电力行业等各种工况的管路上,切断或接通管路介质。旋塞阀的阀体和密封面间设有油槽,可随时通过油嘴向阀座注入密封油脂,增加密封性能。parts材质及法兰尺寸可根据实际工况或用户要求合理选配,满足各种工程需要。

CHAODA Valves Group is specialized in manufacturing API Plug Valve which is suitable for pipeline as the device to cut off or connect the flowing medium in industries such as petroleum, chemical, pharmacy, fertilization, power plant and so on with working pressure from Class 150~1500, working temperature from -29 to 180℃. An injection port is designed between the body and seat, so sealing grease could be injected through it always to ensure the sealing performance. Parts material and valve's flange ends could all be selected according to needs or working condition.


Plug valve could be in manual or electric actuated. Plug valve is the first type of valve used by people with its simple structure, quick opening & closing and small flow resistance. The sealing performance of normal type plug valve is not very well because it relies on the sealing effect between finish machined metal plug with valve body. Moreover, it has a big operation torque with easy to be worn sealing face, so normal type plug valve is generally used in working place with low pressure(smaller than 1MPA) and small nominal size(smaller than DN100)

API Plug Valve product description

    API Plug Valve适用于Class150~Class900的各种管路上,用于截断或接通管路中的介质。选用不同的材质,CHAODA group的API Plug Valve可分别适用于水,蒸汽,油品,硝酸,醋酸,氧化性介质,尿素等多种介质。API Plug Valve的驱动方式为手动,蜗轮传动,气动或电动。API Plug Valve一般采用法兰连接。

API Plug valves(Generally flanged connection) are suitable for use on various kinds of pipeline from Class150 To Class900 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs. 

    API Plug Valve是一种快速开关的直通阀,由于旋密封面之间运动带有擦拭作用,而在全开时可完全防止与流动介质的接触,故它通常也能用于带悬浮颗粒的介质。

API Plug valve is a kind of straight way valve with quick opening & closing function. A kind of scraping function between the sealing face of Plug valve together with the feature that the sealing face wouldn't contact the flowing medium when valve is full opening position makes the API Plug valve suitable for medium containing some particles.

API Plug Valve product features

     CHAODA API Plug Valve has the features of Good sealing, reliable, safety and long life span.

API Plug valves developed by Chaoda have following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.

     CHAODA VALVES GROUP CO.,LTD. launched its quality management and safety system as ISO9001,ISO14001,OHSAS18001, API6D, CE/PED, API607,API6FA, ISO15848-1 TS and API 600.


① A kind of scraping function exists between the sealing face of Plug valve together and the sealing face wouldn't contact the flowing medium when valve is full opening position 


② A 90°'s rotation is needed for the plug type closure member of API Steel Plug valve makes it quite suitable for application where needing quick closing & opening valves.

    ③旋塞阀结构简单易于维修和清理,如紧定式圆维形旋塞阀,拧下紧定螺母,撤下垫圈阀塞便可以从阀体中取出,进行清理和维修。奥氏体不锈钢制成的API Plug Valve门是食品工业和制药工业的最佳选择。 

③ Simple structure enables the valve to be easily repaired and maintained. Austenitic stainless steel API Plug valve is the best choice of valve for food & pharmacy industry.
