Overview：

VOCs emission reduction has become a development requirement for valve low-emission sealing.

The AZ7501 stem sealing element is a high performance packing seal specially developed for low fugitive emissions.

Features：

Excellent compression compensation and low bolt torque; ultra-low thermal weight loss meets Shell Oil's top requirements (670 ℃ ≤4%/h);

Outstanding resistance to temperature shock, pressure shock and mechanical vibration, reliable low emission seal, long life cycle; regardless of installation orientation.

technical parameter：

Temperature resistance range: -196~RT~538℃ (please consult our technology), -48~400℃ (long-term use temperature)）

Pressure resistance: ≤420bar PH value: 0~14 (except oxidant)

Scope of application：

It is suitable for dynamic and static packing seals of various chemicals, gases, oils, seawater and steam and other media, because it is the low torque and low escape sealing requirements for the high and low temperature working cycle of the valve stem.

Range of application:

Suitable for all kinds of chemical, gas, oil and water and vapor, and static packing seal, which is the low torque and low dissipation sealing requirement of stem high and low temperature working cycle.

Passed API622 test (leak rate average 3PPMv); can meet the low leakage requirements of ISO15848 series valve sealing test; meet the strictest fugitive emission requirements in Europe;

Comply with Europe's most stringent unstructured emissions requirements;
