2019-02-18  2019-02-18  The process of cutting rings from rope packing, inserting them into a stuffing box, and torquing them to the right density is familiar, but that is not always the case. Another manufacturing method that EGC has been using since 1978 is called die-molding. It is the process of wrapping a material around a mandrel, placing it in a die and preforming it to make a seal. EGC has

What is the impact of packing friction on valve performance?

During the assembly of the stuffing box the packing is compressed axially to produce a radial contact and hence a force that controls leakage. This radial load has to produce a contact pressure on the shaft or stem and bore high enough to overcome the process fluid pressure. The equipment shaft, spindle or stem drive mechanism has to readily overcome both static and dynamic or running friction during
