Keystone Series GR Butterfly Valve
The Keystone Series GR is a general purpose resilient seated butterfly valve available in flanged, lugged or wafer body style for any service where drop-tight shut-off and maximum flow area is required.
Keystone系列GR蝶閥
Keystone系列GR是一種通用的彈性閥座蝶閥,適用于任何需要液滴關(guān)閉和*大流量區(qū)域的服務(wù)。
Features
· Wafer and lugged body design with face-to-face dimension, according to EN 558 Series 20 and API 609.
· Designed according to EN 593 and API 609.
· The seat is field replaceable and fully isolates the body and shaft from the flow.
· Primary shaft sealing exceeds the pressure rating of the valve and prevents leakage through shaft area to atmosphere.
· A secondary shaft sealing provides back-up safety.
· A molded-in O-ring in the seat for flange sealing eliminates the need for gaskets.
· Shaft seals prevent moisture penetrating into the shaft area.
· The two piece shaft allows for a thin disc and provides minimal obstruction to flow (up to DN 300/ NPS 12).
· Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and drop-tight shut-off.
· Body locating holes allow ease of installation and centering between the flanges.
· Extended body neck allows for pipe insulation.
· Top and bottom shaft bearings for optimized support and minimum friction and decreased torque.
特征
· 根據(jù)EN 558系列20和API 609的要求,采用面對面尺寸的硅片和拉桿體設(shè)計.
· 根據(jù)EN 593和API 609設(shè)計。
· 閥座在現(xiàn)場是可更換的,并且將閥體和軸與流動完全隔離開來。
· 主軸密封超過閥門的壓力等級,防止通過軸區(qū)泄漏到大氣中。
· 副軸密封提供備份**.
· 法蘭密封閥座中的模壓O形環(huán)消除了對墊圈的需求.
· 軸封防止水分滲透到軸區(qū)。
· 該兩塊軸允許一個薄圓盤,并提供*小的阻礙流動(高達DN 300/NPS 12)。
· 圓拋光圓盤邊緣提供**的同心密封,較低的扭矩,更長的閥座壽命和下降緊密關(guān)閉.
· 閥體定位孔便于安裝和在法蘭之間對中。
· 加長的閥體頸允許管道絕緣。
· 頂部和底部軸軸承的優(yōu)化支持和*小的摩擦力和減少扭矩。
