Max. flow              (L/min)

Pressure fluid temperature range（℃）

Maximum permissible degree of contamination of the pressure fluid is to NAS 1638 cass 9. We therefore recommend a filter with a minimum retention rate of β10≥75

Key Features

  • For installation in manifold blocks as right angled check valve cartridge
  • Leak free closure in one direction
  • 6 opening pressures, optional

Industrial Applications

  • It is mainly used in the outlet of pump as back pressure and side through valves.
