性能特點： Performance characteristcs：

1、優質鍛件井經固融處理的閥體，確保無內外裂敏

2、閥座堆焊鈷基硬質合金，極大地提高了高溫硬度和抗介質沖蝕能力

3、閱果用鉆鉻鎢鋼球，具有很高的高溫硬度，使其抗介質中蝕能力大大憂于通針型，

4、經鍛造的閥桿，柔性和強度一同一般，滾壓加工的螺紋位于填料之上，溫免了與介質接，光桿部位經精處理

不僅與填料緊密接觸，保證了密封無外溫，而且液少了開啟力矩，閥門啟閉時靈活自如。

5、設計的中口金屬密封墊，經特殊工藝調質處理，確保高溫高壓下的良好密對

6、致密性優良的柔性石墨填料，確保了高溫高壓下無外溫

7、執行標準：ASM1B16．34

1. The valve body has quality forging and after melts processing (rmly. This can guarantee that does not have the inside and outs

de cracks

2. The valve seat built-up welding cobalt base hard alloy, this can enhance the high temperature degree of hardness and anti-med

ium eroding ability enormously.

3. The valve petal uses the cobalt chrome tungsten steel ball. It has the very high high temperature degree of hardness. This can

cause its an-medium eroding ability to surpass the ordinary needle valve

4. The va e stem is forged, its flexibility and intensity different general. The trundle processed thread located at padding above.

this can avoid contact with the medium, The polished rod spot is processed by correct gridding. This can guarantee the close con

tact with the padding. The valve has no outside leaks. This design can also reduce the opening moment of force and the valve op

ens shuts time nimble freely

5. The unique design mouth metal gasket is manufactured by special craft quenching treatment. This can guarantee the good se

al in the high temperature and high pressure.

6. The compact fine flexible graphite padding, has guaranteed the valve has not outside leaks in the high temperature high press
