概述：
VOCs減排已成為閥門低逸散密封的發(fā)展要求。
AZ7501閥桿密封元件是專為低逸散排放研發(fā)的高性能填料密封。
Characteristics:
VOCs emission reduction has become the development requirement of valve low escape seal.
The AZ7501 stem seal element is a high-performance packing seal developed for low dissipation emissions.
特點(diǎn)：
優(yōu)秀的壓縮補(bǔ)償性和低螺栓扭矩；超低的熱失重符合殼牌石油要求 (670 ℃ ≤4%/h )；
突出的抗溫度震蕩、抗壓力振蕩和機(jī)械振動性能，可靠的低逸散密封、長壽命運(yùn)行周期；無需考慮安裝方向。
Characteristics:
Excellent compression compensation and low bolt torque;The ultra-low heat loss complies with shell's top requirements.(670 ℃ ≤4%/h );
