Parker Low-Torque™ Grafoil® Bonnet and Packing Design
Parker Low-Torque Grafoil Bonnet
Grafoil® Stem Seal Torque Reduced 50%
PGI answered customer requests for a lower stem handle turning torque by introducing their new Low-Torque™ Grafoil® bonnet and packing design. It is the nature of Grafoil® packing that it is easily abraded away by the rotation of the valve stem. This abrading requires periodic packing compression adjustment to stop stem seal leaks. Parker developed a proprietary assembly technique to lower stem torque by 50% which increases ease of operations, and therefore reduces stem abrasion and stem damage from over-torquing. The Low-Torque™ Grafoil® packed stem seal reduces packing adjustments and the associated maintenance costs while extending the service life of the Grafoil® packing.
