Systems capabilities designed to help you... When hydraulic systems were first used in mobile equipment that moved earth, plowed crops, built highways, dug trenches and loaded materials, Vickers fluid power was there. Today, Vickers is a global leader in designing and manufacturing complete fluid power systems that move the world’s most powerful mobile machinery. Vickers has the expertise needed to provide you with complete fluid power system solutions, including the huge product selection previewed on following pages. We also offer in-depth knowledge of your market, and system design know-how...

Vane pumps, triple fixed displacement type Vickers fixed displacement triple pumps offer: displacements from 61,3 to 336,8 cm3/r (3.75 to 20.6 in3/r); continuous pressures to 210 bar (3000 psi); speeds to 2700 r/min. All models can be provided with integral valving to limit flow to the operating system, to limit maximum system pressure, and to divide flow between two circuits.

Hydraulic Remote Control HRCs (hydraulic remote controls) are available in hand, foot and mechanically operated versions, designed for pilot pressure actuation and control of remotely located directional valves. They are used in applications where hydraulic pilot operation of system components is controlled from one operator station. The HRCs operate on input flows up to 16 l/min (4.2 USgpm) and pressures up to 110 bar (1600 psi) or 150 bar (2200 psi), dependent on the model and the type of response required for the application. HRCs require input pressures equal to the maximum required output...

Directional Control Valves / Proportional Directional Valves Vickers offers a complete line of mobile directional control valves designed for flexibility, easy application and performance. These valves come in various sizes and operators... solenoid, hydraulic, air, cam or lever to meet a wide range of applications. A soft shift feature is designed to provide smoother control of actuator acceleration and deceleration. The electrically actuated valves use industry- standard connectors to make installation and replacement easier and faster. Our valves use many common connectors such as...Packard...

Directional Controls, Sectional Construction These manually, hydraulically and electrically actuated spool type valves are comprised of sections that are internally connected to common pressure and tank return passages. Seals between the sections seal the connecting passages, and the sections are held together by studs and nuts. Valve sections are available as assembled banks, and as separate sections for assembly into banks or to add to or change the functions of a bank.

Engineering Applied Valves Each product in this group is designed for a specific application and meets the needs of improving environmental adaptability, design flexibility, increased productivity, and improved safety and reliability. The LT Sectional Directional Control Valve can be actuated manually by levers or hydraulically with a hydraulic remote control and is available in 2-10 section configurations, providing flexible options for specific customer requirements. The EPM Electro-Hydraulic Lift Truck Valve incorporates products such as the Valvistor (EPV) valve and the KTG4V-3S valve into...

Auxiliary Valves The RM3 is an internally pilot operated relief valve providing pressure protection to a hydraulic system. The FM3 is a bypass type pressure compensated flow control and a relief valve. It is used in applications where a constant actuator speed is required in the face of varying pump output. The ACX2 pilot pressure supply unit is used to feed one or more Vickers HRC or other similar hydraulic remote control. It maintains pilot pressure within preset limits when inlet pressure varies above the minimum set reduced pressure. Symbol Model Port Size Max. pressure Max. flow bar (psi)...
