Piston seal / DG

Product introduction:

          未标题-1.jpg


The double acting DG is a combination of a Centflon based slipper seal and an energising O-Ring. It is produced with 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 DG against the sealing face with increased force.

Advantages:
  • - No stick-slip effect when starting for smooth operation
  • - Minimum static and dynamic friction coefficient for a minimum energy loss and operating temperature
  • - High wear resistance ensures long service life
  • - Suitable for most hydraulic fluids in relation with most modern hardware materials and surface finish
  • - Suitable for new environmentally safe hydraulic fluids
Operation condition:

Pressure:         Up to 80 MPa

Velocity:          Up to 15 m/s

Temperature:  -45°C to +200°C

                        depending on O-Ring material
