Description:Braided from low-sulphur expanded graphite yarns, which are reinforced by cotton or glass fiber. Corrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box, It has a very low friction, does not damage shafts or stems. It shows good thermal and chemical resistance and high elasticity.
APPLICATION:
ZR-200H & ZR-200Z is a multi-service packing capable of a wide variety of uses throughout a plant. It can be used in valves, pumps, expansion joints, mixers and agitators in high-pressure, high-temperature hostile environments of hydrocarbon processing, pulp and paper, power stations, refineries and industries where effective sealing is vital.
Precaution: in oxidizing environment.
Recommendation:
Use preferably with ZR-544 high carbon fiber anti-extrusion packing rings.
