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
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

100 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
 
1. 防靜電裝置（球之間的電連續性，閥桿和閥體）
避免靜電這可能會導致在易燃/爆炸的環境中有火花而火
整個閥的整個生命聯系**

墊圈2.雙擊抗磨
較少破壞力矩被授予
減與單墊圈

3相比，磨損更明顯。3個密封件+ O形圈
即使在經過多次循環后仍可確保**的密封性。4.軸墊圈上的彈簧墊圈確保由于軸的旋轉運動引起的磨損而恢復間隙，避免向外泄漏部分。



保持通電的“ V形”密封（V型），從而避免任何泄漏，防止外部發生巨大的溫度波動

。5。拉伸石墨密封件不受外界溫度影響
，使閥門的外部密封性

更高。在從原材料到成品閥門的過程中進行獨特的加工定位，從而實現軸的對齊閥門的
使用壽命更長，
