 Design introduction

屏幕截图 2025-09-25 161206

The double-acting Seal is a combination of a Rubber Material based slipper seal and an energizing O-Ring. It has an interference fit which together with the squeeze of the O-Ring ensures a good sealing effect even at low pressure. At higher system pressures, the O-Ring is energised by the fluid, pushing the seal ring against the sealing face with increased force.



Advantages

  • No stick-slip effect

  • Minimum static and dynamic friction for a minimum energy loss and operating temperature

  • High wear resistance

  • No adhesive effect to the mating surface during long period of inactivity or storage

  • Available for all cylinder diameters up to 2,700 mm.
