Features and advantages

1 Concise switch indication
·The valve stem head indication is consistent with the ball flow channel
·Effectively avoid the operator's switch misjudgment
2 Drive connection and locking function
·The valve body and drive connection flange meet the I50 5211 standard

·The manual ball valve has locking anti-vibration and anti-misoperation functions
3 Unique elastic valve seat design
·The valve seat has wear-resistant automatic compensation characteristics
Low opening torque, long service life, good sealing performance
·Eliminate cold flow and meet high and low pressure alternating working conditions
4 Low fugitive packing structure
The packing structure meets the low fugitive requirements
Meet the requirements of ISO15848A/B and TA-LUFT
5 Anti-blowout and anti-static valve stem
·Anti-static structure is designed between the ball, valve stem and valve body

·The valve stem is designed as an anti-blowout structure
6 Assembly without adjustment design
The left and right body connections are quantitatively compressed, and the metal surface contacts after assembly, without adjustment

Assembly and maintenance are very simple, with 100% interchangeability
7 Fireproof design in accordance with API607/API6FA
·The valve has fireproof function

Meet the requirements of API607/API6FA
