lAdaptor size 3 to size 2
l Single-station subplate
lMulti-station subplates
l ISO 02 Adaptor plate
In response to growing demands for a valve system smaller than size 3, Vickers participated in the development of the ISO 4401 size 02 interface standard and then designed the relevant products. Vickers experience as the leading worldwide supplier of size 3 valves played a major part in achieving design and development programs for these small valves.
All the basic functions of the well established and field-proven size 3 range are now available in a smaller package size for pressures up to 250 bar (3600 psi) and flows up to 30 l/min (7.9 USgpm).
These latest performance specifications are achieved through improved design and manufacturing
methods, and the use of modern high-efficiency solenoids, combined with pro-active attention to quality.
In response to requests for a solenoid controlled directional valve that can be driven directly from a Programmable Logic Controller (PLC), the DG4V-2 valve is available with a low power (500 mA) coil for pressures up to 165 bar (2300 psi) and flows up to 20 l/min (5.3 USgpm).
The range allows for complete systems to be designed and implemented in Vickers SystemStak configuration, giving significant reductions in space requirements compared to size 3, while achieving high performance levels.
The drawing illustrates the reduced installation dimensions of a size 2 control system compared to size 3, both having the same functions-a space saving of up to 40% on manifold systems.
The size 2 product range has been designed, developed and manufactured to the high standards that continue to assure Vickers customers of complete satisfaction with regard to performance and reliability. Testing ensures that all size 2 valves have a fatigue and endurance life in excess of 10 million operating cycles at maximum pressure.
All Vickers customers and products are backed by worldwide customer support facilities.
Manually Actuated Control Valves
DG2/17/21V-2 10 Series
General description and application benefits
Vickers directional valves offer versatility of application for the many directional control requirements of hydraulic machinery. Ruggedness of design, manufacturing quality, and worldwide parts and service availability maximize uptime.
These valves are available in an ISO/DIS 4401-02-02 interface. Lever operated, roller cam and plunger
operated models offer the following application benefits:
l Efficient control of high hydraulic powers, ideal for such applications as gate valves.
lLow internal leakage reduces power losses, increases system efficiency - the result of improved manufacturing techniques for spools and bores.
lViton®seals with multi-fluid capability without need to change seals.
lHigh sustained machine productivity and higher uptime because of proven fatigue and endurance life- tested to over 10 million cycles.
lCompact and cost-effective system design when used with Vickers SystemStakTM valves and multi-station subplates.
Solenoid Operated Directional Valves
General description and application benefits
These solenoid operated directional control valves are for directing and stopping flow at any point in a hydraulic system. The features being released with this range are based on Vickers experience with size 3 valves.
lEfficient control of high hydraulic powers with low solenoid power consumption.
lLow internal leakage reduces power losses, increases system efficiency - the result of improved manufacturing techniques for spools and bores.
lViton®seals with multi-fluid capability without need to change seals.
lHigh sustained machine productivity and higher uptime because of proven fatigue and endurance life- tested over 10 million cycles.
lCompact and cost-effective system design when used with Vickers SystemStakTMvalves and multi-station subplates.
