1. Antistatic device (electrical continuity between ball, stem and body)
Static electricity is avoided which can cause sparks and fire in an inflammable/explosive environment
Contact safety throughout the entire life of the valve
2. Double antifriction washer
Less Breakaway Torque is granted
Less wear comparing with the execution with the single washer
3. "V" seals pack; 3 seals + o-ring
It ensures a perfect tightness even after a high number of cycles

4. Spring washer on the shaft seal

1.防静电装置（球之间的电连续性，阀杆和阀体）
避免静电这可能会导致在易燃/爆炸的环境中有火花而火
整个阀的整个生命联系安全

垫圈2.双击抗磨
较少破坏力矩被授予
减与单垫圈

3相比，磨损更明显。3个密封件+ O形圈
即使在经过多次循环后仍可确保*的密封性。4.轴垫圈上的弹簧垫圈确保由于轴的旋转运动引起的磨损而恢复间隙，避免向外泄漏部分。



保持通电的“ V形”密封（V型），从而避免任何泄漏，防止外部发生巨大的温度波动

。5。拉伸石墨密封件不受外界温度影响
，使阀门的外部密封性

更高。在从原材料到成品阀门的过程中进行的加工定位，从而实现轴的对齐阀门的
使用寿命更长，
分离扭矩更小

碳钢阀体以NACE材料为标准制成
更高的耐腐蚀性
更高的材料延展性

100％ -房屋制造过程技术
在制造过程的所有阶段都具有*的控制力和准确性
供应迅速灵活，可按客户要求提供特殊执行

“防火”证书
，即使在发生火灾时也可确保阀门的密封性

ATEX证书
可在潜在爆炸性环境中安装

TA LUFT散逸性排放证书
高度安全获得

PED证书
完全符合压力设备的欧洲安全标准，*

达到SIL 3
保证高水平的功能安全
Guarantee of the recovery of the gap due to the wear caused by the rotational movement of the shaft avoiding leakage towards the outside part.
Allow to maintain energized the "chevron" seals (V), thus avoiding any leakage to the outside, against huge temperature excursions
5. Stretch Graphite seal
Tightness towards outside is granted, independently by the thermal excursions to which the valve is subjected
Greater precision in the alignment of axes due to a unique positioning in the process machining from raw material to finished valve
Longer lifetime of the valve
Less breakaway torque
Valve body in carbon steel made with NACE certified material as standard
Greater corrosion resistance
Greater ductility of the material
* in- house manufacturing process technology
Maximum control and accuracy in all the stages of the manufacturing process
Flexibility in supply quickly special executions requested by customers
"Fire safe" Certificate
Guarantees the tightness of the valve also in case of fire
ATEX Certificate
Installation is possible in a potential explosive environment
TA LUFT fugitive emission Certificate
High level of safety of the tightness towards the outside is granted
PED Certificate
Full compliance with European Safety Standards for Pressure Equipment
UP to SIL 3 certified
Guarantee of the high level of functional safety
