The DONADON “GM” mono-block graphite rupture disc is a versatile disc suitable for numerous applications and can be directly inserted between flanges.
It conforms to EN ISO 4126-2 norm
TRIGGER SPEED: This disc opens immediately and totally.
OPERATING MARGIN: Good operating margin. Ratio between operating pressure and rupture pressure up to 80%.
FRAGMENTATION: Total fragmentation.
CORROSION: Good resistance to aggressive fluids.
VACUUM: Vacuum support is required only for rupture pressures below 1.7 Bar. At higher calibrations the disc is self-supporting.
Nominal size: from ND 15 to ND 600
Bursting pressure: from 0.017 to 10 Bar at 22°C
Bursting temperature: 370°C
Bursting tolerance:
- below 1 Bar: ± 0,05 Bar
- over 1 Bar: ±10%.
Standard material: high purity graphite impregnated with phenol resins
Accessories: seals, support for vacuum, linings and rupture Indicator
Holder: Not required (installed directly between flanges) |

Universal Arma-Gard™ is an engineered graphite bursting disc device. Its patented design overcomes problems associated with damage of conventional graphite bursting discs, caused by poor storage, handling and installation practice; as it is not adversely affected by misaligned, poorly supported pipework, over or uneven torquing of pipe flange bolts. This is achieved through the use of a steel armoured ring, which protects the graphite bursting element, whilst allowing the clampage necessary for correct sealing.
The Universal Arma-Gard™'s monobloc type design requires no holder, enabling direct fitting between flanges.
Unlike conventional monobloc designs the Universal Arma-Gard™ eliminates the possibility of side wall bursts. All these added benefits do not detract from excellent corrosion resistance and low pressure capability normally associated with graphite bursting discs. |

Controller-One
CONTROLLER-ONE is a seal set of variable geometry, planned and produced to answer the request for a secure product, reliable and corresponding to the regulations concerning the reduction of the fugitive emissions of VOC and HAP. In the middle are three graphite rings with a conical torso configuration of very low density "activated" by two graphite rings with a conical torso configuration at a different angle and at high density. All that is contained by two, GR8807 Incobraid® rings, as wiper and Anti-Extrusion Rings: here is the Controller-One configuration! The innovative conical torso configuration of the graphite rings with different density that allows a great radial expansion already with modest torque loads. It fully utizes the elastic properties, reducing the friction strength exercised by the gasket on the stem during the movement, also decreasing damage sustained by the gasket itself, allowing a reduction of the effort requested by the actuator in the motion act. The great radial expansion capacities of the Controller-One is able to execute with success of the re-torque required to compensate the loss of weight of the gasket caused by the scratching of the stem, and keeping an unchanged seal efficiency troughout a long period of time.
