產(chǎn)品特點(diǎn)Features：
手輪螺母采用雙軸承支撐，的減小閥門啟閉所需的力矩。Two thrust bearing design to reduce the torque of handwheel operation.
支架與閥體整體鍛造，體積小，結(jié)構(gòu)緊湊，強(qiáng)度高。Forged body with integral yoke provides compact construction and greater rigidity.
采用楔式石墨環(huán)加蝶形彈簧的填料組合，對填料的預(yù)緊提供動態(tài)補(bǔ)償，避免填料失效。 High quality graphite packing with Belleville spring provide continuous and stable sealing force.
閥門內(nèi)件采用可更換的閥芯、閥座和閥籠，方便檢修，節(jié)約時間和成本。The cage , plug and seat are all replaceable with the valve in line reducing maintenance costs and down time.
內(nèi)件材質(zhì)均為奧氏體不銹鋼，耐熱性能優(yōu)異，并能防止生銹而引發(fā)的內(nèi)漏，密封面都為堆焊的司太立硬質(zhì)合金，硬度高，抗沖刷。The cage, plug and seat are all made from stainless steel suitable for high temperature service and corrosion resistance. The seat and plug are hard faced with stellite to provide resistance to erosion.
