Slip-in Cartridge Valves

Danfoss Vickers Slip-in Cartridge valves are generally used in medium to high pressure hydraulic systems, where flows may be greater than 150 L/min (40 USgpm), to provide power transmission and motion control in a wide variety of applications.  These space-saving valves are exceptionally cost effective and energy efficient, while maintaining machine design flexibility and reliability.

Construction

Danfoss Vickers cartridge valves are similar to poppet check valves and consist of an insert assembly that slips into a cavity machined into a manifold. This cavity is made to ISO 7368 or to DIN 24342. The insert is retained in the cavity by a control cover which is bolted to the manifold. The insert consists of a sleeve, poppet, spring and seals. Typically, inserts and covers are supplied separately. For some functions, inserts and covers are supplied as a complete assembly.

Grouping cartridge assemblies for control by one or more common pilot valves can provide directional, check, pressure and/or flow restrictor functions for flow rates up to 5500 L/min (1450 USgpm) per cartridge.

Functions

Cartridge valves for directional and check functions are essentially hydraulically piloted check valves. Cartridge relief valves feature manual pressure setting adjustment. Additionally, venting and remote piloting are possible. Alternative arrangements include electrical selection of pressure or venting, and of dual pressure settings and venting, via a pilot valve mounted to the cartridge cover. Electrohydraulic proportional control of pressure is also available.

Relief valve arrangements can be built into system manifold assemblies in combination with directional flow regulating and pressure reducing functions in cartridge form. The basic pressure reducing cartridge arrangement features manual adjustment of reduced pressure, plus a pilot port for optional remote control. Options include electrical selection of high and low pressures, and electrohydraulic proportional control of reduced pressure.
