Descrizione
PISTON SEALS (PDE)
Double acting piston seals are designed for alternating applications in oleodynamic and pneumatic range, made in NBR compound with an hardness of 85° Shore A. They are fitted with expansion-springs, able to ensure a right pressure on the radial contact, in order to grant the following limits.
| Pressure | Temperature range | Speed |
| up to 40 BAR (4 MPa) in oleodynamic application up to 10 BAR (1 MPa) in pneumatic application |
-25 – 100 °C | up to 0,5 m/s |
Over these pressure limits support flanges are recommended: in case of contact with aggressive fluids, the following
materials are used:
- FKM compound,
- AISI 304 springs,,
- AISI 316 support disc
