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.防靜電裝置（球之間的電連續(xù)性，閥桿和閥體）
避免靜電這可能會(huì)導(dǎo)致在易燃/爆炸的環(huán)境中有火花而火
整個(gè)閥的整個(gè)生命聯(lián)系安全

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(gè)密封件+ O形圈
即使在經(jīng)過多次循環(huán)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(zhuǎn)運(yùn)動(dòng)引起的磨損而恢復(fù)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(fā)生巨大的溫度波動(dòng)

。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(jìn)行的加工定位，從而實(shí)現(xiàn)軸的對(duì)齊閥門的
使用壽命更長(zhǎng)，
分離扭矩更小

碳鋼閥體以NACE材料為標(biāo)準(zhǔn)制成
更高的耐腐蝕性
更高的材料延展性

100％ -房屋制造過程技術(shù)
在制造過程的所有階段都具有*的控制力和準(zhǔn)確性

“防火”證書
，即使在發(fā)生火災(zāi)時(shí)也可確保閥門的密封性

ATEX證書
可在潛在爆炸性環(huán)境中安裝

TA LUFT散逸性排放證書
高度安全獲得

PED證書
完全符合壓力設(shè)備的歐洲安全標(biāo)準(zhǔn)，*

達(dá)到SIL 3
保證高水平的功能安全
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
