性能特點

1、體、支架均鍛造后固融處理，結構緊密無裂痕，耐高溫高壓效果*

2、閥座堆焊硬質合金司太立6號，高溫硬度達50HRC以上

3、桿鍛造后取得了良好的抗拉強度和屈服強度，承受高溫高壓性能*

4、為司太立8號整體鍛制而成，高溫硬度達HRG58以上，與閥座形成了合適的硬度差，互相配合后具有良好的抗沖

刷、抗氣蝕性能。

5、閱體內置閥桿導向座，閥門長期反復開關時，閥瓣回座率達100，保持了良好的密封性能

6變架上端置閥桿直升降裝置，閥門開閉時，閥桿的無旋轉直升降運動不僅減少了對填料的磨損，而且啟閉力小，手

松

7、致密和回彈性優良的柔性石墨填料，確保閥門不外漏

Performance characteristics

1. The body and supporting are all solid melting treated after forged. The structure is compact without any crack. High temperature

d high pressure resistant performance is excellent

The seat is buill-welded with hard alloy steel STL 6, the hardness is more than 50HRC

3. The stem has good tensile strength and yield strength after forged, High temperature and high pressure resistant performance is

excellent

4. The petal is integrally forged by STL 8, the hardness is more than 58HRC, it has suitable hardness difference with the seat

5. There is valve stem guide seat in the body, after the valve is opened and closed repeatedly for a long time, the retum rate of the

petal is 99%. The sealing performance is good.

6. Stem straight lifting device is on the top of the supporting. when the valve is opened and closed, non rotating lifting movement of

the stem can reduce the wear of the filler. The opening and closing force of the valve is small

7. Flexible graphite filler is compact and its elastic resilience is excellent, this can guarantee the vale has no extemal leakage

安裝維護說明

1、產品出廠時已經嚴格檢驗，請勿解體，可打光譜，可試壓

2、閥門盡可能按閥桿垂直水平面安裝，如需其他方法安裝，請說明

3、安裝時應使介質流向與閥體所示箭頭方向一致，切勿裝反

4、次使用時，須全開閥門，對閥門及管道進行清洗。調整壓板螺母，確保填料處于良好密封狀態

5、運行中，當工況溫度變化較大（如停機維修）時，襝查并旋緊壓板螺母，壓緊填料。以防閥桿處外溫

Installment and maintenance instructi

1. Our valves have been examined strictly when leave the plant, please do not disintegrate. You may hit the specrum an

on the pressure test

2. Along the valve stem vertical horizontal plane to install the valve as far as possib you need other instalment please

3. When installing the valve, you should cause the medium to flow consistent with the arrow direction, do not install instea

4. When installing the valve, please open the valve completely, clean the valve and the pipeline. You should tighten thes

nis can guarantee the good seal of the padding

Th

5. In the working time, if the situation temperature changes greatly, please check and tighten the clamp nut, compact the

thus the outside leakage from the valve stem will be prevented
