Controller-One

Composition Cap&Cone Flexible graphite formed Rings with differentiated bulk density Wiper's rings Incobraid® GR8807 Features 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.
