Description:CAZ die formed ring are made of low-sulphur expanded graphite without any fillers or binders. They are compressed in precise moulding tools to the required density. Due to the high purity of the material (>98%), no special corrosion protection is required. In general, it has square section and also has V-shaped and wedge-shaped section, the rear two kinds style are suitable for high pressure sealing.
CONSTRUCTION:
CAZ 241E¡ªReinforced Die formed Graphite Ring
Moulded from pure flexible graphite with reinforcement, the insert materials stainless steel foil or mesh etc. are available on request. To protect against oxidation, the stainless steel cap is necessary.
241K¡ªDie formed Graphite Ring with Corrosion Inhibitor
Corrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box.
241EK is reinforced graphite ring with corrosion inhibitor.
APPLICATION:
It has all properties of expanded graphite, can bear violent alteration of temperature and pressure. It is ideal packing for valves and static seal in almost all applications. Can be used as stand-alone packing or in combination 244 high carbon fiber anti-extrusion packing rings, except when stems are severely damaged.
CAZ have cooperation with more famous Valve manufacturer in the world.
