● 開關無磨擦：偏心設計消除了與閥座的摩擦，解決了傳統(tǒng)球閥、 閘閥、 旋塞閥閥座的磨損問題。
● 單閥座設計：靜態(tài)單閥座，能保證下游密封零泄漏，避免了雙閥座內(nèi)腔壓力升高的問題。
● 自清潔功能：當閥芯偏離閥座時，介質(zhì)可沿密封面360度流動，將密封面上的雜質(zhì)沖洗干凈。
● 低扭矩操作：因為密封摩擦被消除了。閥門密封面無摩擦，轉動輕便。
● 耐磨硬密封面：閥芯密封面堆焊硬質(zhì)合金， 能滿足在非?？量痰慕橘|(zhì)場合下的密封性。
● 雙偏心設計：整合了眾多閥門設計的優(yōu)點， 克服了傳統(tǒng)球閥在深冷、固料磨損、高低溫切換、高頻次開關、雙向關斷等苛刻工況的多種缺陷，以滿足苛刻工況最高可靠性和安全性的要求。
● 全通道設計：開放式流道，無空腔死區(qū)，無閥腔堆積，無需專門泄壓排放。

There is an oil groove between the valve body and the sealing surface of the pressure-balanced plug valve, and sealing grease can be injected into the valve seat through the oil nozzle at any time to improve the sealing performance. The material of the parts and the size of the flange can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
It is mainly used for storage and transportation of oil and gas in the chemical industry, metallurgy, paper making, food processing, shipbuilding and other industries, used to open or close, and with pneumatic and electrical devices can also achieve the long-distance operation, to ensure personal safety.
