The valve features two parallel gate plates and a wedging device, updating the traditional single gate plate design.
Sealing elements are designed as separate components, which prevents deformation from thermal expansion and temperature
differences, ensuring a reliable seal.
The materials used for the sealing components are resistant to wear and corrosion, enhancing the valve's longevity.
It is equipped with a bidirectional forced sealing capability, which simplifies operations and ensures a dependable seal.
The fully enclosed design of the valve provides excellent protection, allowing for operation in all weather conditions.

全焊接球閥閥體采用優(yōu)質(zhì)材料鍛制而成，球體側(cè)裝，中法蘭和頸部采用全焊接連接。全焊接球閥有筒形全焊接閥體結(jié)構(gòu)和球形全焊接閥體結(jié)構(gòu)兩種形式。浙江歐菲主要生產(chǎn)的是筒形閥體結(jié)構(gòu)的全焊接球閥。浙江歐菲擁有一整套成熟的低殘余應(yīng)力、低韌性損耗的焊接技術(shù)，以國際先進標準為依據(jù)，用焊接接頭斷裂韌度CTOD值進行免焊后熱處理安全評估。浙江歐菲不同材質(zhì)間的焊接工藝均經(jīng)過獨立認證權(quán)威機構(gòu)TUV的認證，焊接接頭的安全性通過專家評估。根據(jù)球閥公稱尺寸與公稱壓力，我們可以提供的全焊接球閥有：全焊接固定球閥和全焊接浮動球閥?？梢愿鶕?jù)客戶的使用工況，提供閥桿加長型埋地式全焊接球閥。閥桿加長的尺寸是由客戶來提供的。
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate 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 the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
浙江歐菲鋼制球閥的設(shè)計制造保證了最大的使用壽命和可靠性。所有球閥完全滿足美國石油協(xié)會標準 API 608 & API 6D 和英國標準 BS 5351 的設(shè)計要求，并符合美國機械工程師協(xié)會標準 ASMEB16.34。
