Match the tank mounting pattern, inlet position and available internal depth. The MAR catalog permits other discharge pipe lengths by request. Include the desired length and the actual tank drawing in the specification.

Sizing the return filter

Select by the return flow and element grade. For example, the VLR table lists 280 L/min with 20 µm media and 230 L/min with 10 µm media for VLR 12 at the listed pressure drop. Leave room above the tank for the removal and installation of the element.

Connections and service access

Specify the actual inlet and outlet geometry. Some standard FS sizes use different connection types on the two sides. For VLM, identify the body, the connection code and the relative port heights. Leave room to remove the element and read the indicator where fitted.

Interpreting the suction data

Treat the published flow and pressure loss as paired test points for the stated clean element and viscosity. A colder oil or loaded element can increase inlet restriction. For a VLF arrangement, follow the manufacturer’s service instructions for using the integral valve and verify that the normal operating flow path is open.

DX-32 / DX-31 / DX-21 / DX-20 / DX-16	Additional magnetic switch families	Confirm voltage, output type, wiring, cable length and connector for the exact version.
PI / PM / PAC / PN / PBN / BK	Steel mounting bands	Match the cylinder body diameter, switch style and available installation space.
KXY	Sintered exhaust silencer family	Match the exhaust thread, flow and permitted backpressure.
CL	Coiled hose family	Specify material, tube outside diameter, usable reach and the end connection.

Switch and bracket selection

Check the cylinder for a magnetic piston and identify its switch groove or band mount. Compare the selected switch output to the control input, including supply voltage, current and wiring arrangement. Confirm the sensing location at both ends of the required stroke.

Exhaust and tubing selection

A silencer can affect exhaust backpressure and actuator cycle time. Include the expected exhaust flow when sizing it. For coiled tubing, allow movement throughout the full travel and confirm that the tube and fitting share the same outside diameter and compatible material.
