GJ Metal to Metal Seat Ball Valve owns not only various advantages of common industrial ball valves, but also parlicularand outstanding characteristice in heat-durability, especially when soft seal could not be used, such as in pipeline delivery of medium with high friction dust, slurry, and solid foreign matters mixture.
闕座是不銹鋼基體堆焊司太立合金，球體是以不銹鋼為基體采用表面鍍硬鉻、真空鍍膜—鎢鈦合金和堆焊司太立合金等三種表面處理技術，以滿足耐熱和耐磨的要求，GJ的球體制造工藝具有獨創性，可實現球體的高精度，超鏡面加工，GJ金屬閥座球閥的另一大特點是：彈簧予壓閥座，保證密封的絕對可靠性和操作扭矩穩定。從結構設計商保證了使用安全，密封可靠，操作靈便。
The seat is of stainless steel body with Stellite alloy pile-up welding. The ball is of stainless steel body,with threesurface treatment technique as hard chrome plating, vacuum coating and tungsten-titanium alloy and Stellite alloy pile-upwelding etc. Adopted so as to meet the heat resisting and wear resisting requirement. GJ ball manufacturing process iscreative, which realizes high-accuracy and super mirror surface processing of the ball. Another feature of the metal seat ballvalve is spring prepressing seat, which ensure the absolute reliability of seal and stability of operating torque. It ensuresabsolute safety, sealing reliability and operating flexibility and convenience in structural design. |
| 特點 |
1.使用壽命長的球體·閥座Long life ball．seat
閥座密封面為司太立合金，球體密封面為鍍硬鉻、真空鍍J膜—鎢鈦合金和司太立三種形式；對各級使用溫度和高摩擦性粉塵，漿體，固體類異物混入的管線輸送，具有相當的耐摩擦性和長久的使用壽命。
The seat is of Stellite alloy surlace, and the ball sealing face is of three forms as hard chrome plating, vacuum coating andtungsten-titanium alloy and Stellite alloy etc. It owns good friction-resistance and long life for pipeline delivery of mediums withvariousin operating temperatures, high friction dust, slurty，and solid foreign matters mixture.
2.高精密度球體·高密封性閥座High precision ball．High tightness seat
金屬閥座，密封性差是其弱點，但是GJ研制的金屬密封球閥具有非常高的密封性。靠彈簧預壓閥座，保證低壓時的密封性，高壓密封由閥座活塞效應保證，其中最關鍵的是GJ獨創的球體加工工藝，確保球體的高精密度（圓度）。先進的閥座結構，高精密度的球體?*鉤裳廈苊芊獾鬧饕蛩亍Ｍ幣布蟮慕檔土瞬僮髖ぞ亍?BR> While metal seat shows the weak point of low tightness, GJ Metal to Metal Seat Ball Valve has high tightness. It ensuresthe tightness vis spring prepressing seat in case of low pressure; in case of high pressure, the tightness is secured via seatplunger effect. The key point is the original GJ ball processing technic, which ensures the high precision of the ball(roundness). Advanced seat structure and high precision ball are the main factors of high tighness. At the same time, itextremely reduces operating torque. |

3、應用范圍廣泛的金屬閥座Metal seat that is widely applicable
一般的軟閥座，半開狀態容易損傷閥座、有的流體不可使用、溫度范圍狹窄、用途受限。GJ金屬密封球閥高硬度金屬閥座、使用于高溫流體、高摩擦性粉塵、漿體、含撞擊物介質、固形異物混入等，幾乎所有流體均可使用。
The ordinary flexible seat is easy to damage when in half-open position, while it can not be applied for cerain liquids, withnarrow range of temperature and restricted use. GJ Metal to Metal Seat Ball Valve with high hardness metal seat is applicablefor high temperature liquid, high friction dust, slurry, transmitter with impacting substances and solid mixtures etc.1t is nearlyapplicable for all liquids.
4、 兼備球閥的所有特征It owns all features a ball valve may have
比較閘閥、截止閥而言，具有更多特點的GJ金屬閥座球閥，兼備球閥的所有特征，流阻小，操作閥桿轉動900即可實現快速關閉，手動、自動的轉換容易，便于自動化控制。
Compared with gate valves and globe valves,GJ ball valve with metal seat bears more advantages. It has all features aball valve may have such as small flow resistance, 900 .operating valve lever for quick close, easy shift between manual andautomatic operation etc., Which facilitates the auto control.
5、安全防火靜電的最理想閥門The best valve to fire and static resistance safety
金屬閥座，耐500℃極限高溫，具有天然的防火防靜電功能。
Metal seat is resistant to extremely high temperature of 500℃,with the function of fire and static resistance
最具經濟性的材質組合The most economical material combination
6、 GJ金屬密封球閥，根據不同的使用工況，選用不同的密封副，可實現最經濟的合理選擇。
The most economical point lies in that GJ Metal to Metal Seat Ball Valve selects different seals according to differentwork condition
7、任意選擇操作方式Free selection of operating modes
GJ金屬密封球閥，根據閥門的尺寸和使用目的，可選著各種操作機構。
GJ Metal to Metal Seat Ball Valve has the function that different operating mechanism can be selected according to different valve size and application purpose. |
