The 63FLDK(N) duplex filter is suitable for inline installation.

It basically consists of two filter housings (2) with switchover fitting (1), a threaded filter cover (3), filter element (4) as well as mechanical optical maintenance indicator (11).

Via the inlet, the hydraulic fluid reaches the filter element (4) where it is cleaned. The dirt particles filtered out collect in the filter element (4) and in the filter housing (2). Via the outlet, the filtered fluid enters the hydraulic circuit.

By means of the switching lever, you can switch between the two filter housings without operational interruption.

The filter housing and all connection elements are designed so that pressure peaks ‒ as they may e.g. occur in case of abrupt opening of large control valves due to the accelerated fluid quantity ‒ can be securely absorbed. One magnetic screw (8) is included in the standard equipment. The magnetic screw only collects magnetic contamination particles.

Via the bleed screws (standard) and/or bleed valves ‒ amending ordering code E (7) ‒, the filter side to be maintained can be bled. The measuring ports (9) at the side of the connection flange are drilled as standard. Optionally, threaded couplings ‒ amending ordering code M ‒ can be ordered.

As an option, the filter is available with a base (10) ‒ amending ordering code FB. The optional pressure equalization line (13) serves to simplify the filling and bleeding in a filter element exchange. The pressure equalization line is necessary in order to prevent unwanted aeration.

By default, the filter is equipped with mechanical optical maintenance indicator (11). The electronic switching element (12) which has to be ordered separately is attached to the mechanical optical maintenance indicator (11) and held by means of a locking ring.

The electronic switching elements with 1 or 2 switching points are connected via a mating connector according to IEC-60947-5-2 or via a cable connection according to EN17301-803.
