Sun Hydraulics has launched the industry’s smallest high speed, reduced power logic valves with a 10 ms typical response time in an incredibly small package with few moving parts.
The new solenoid-operated Digital Logic Valve (DLV) family paves the way for smaller, highly reliable solutions in demanding mobile applications where size, weight, speed, and power consumption matter and in industrial applications where an extremely fast valve can help reduce machine cycle times.
The first product introduced in the DLV family, the DLVB, is a very fast 2-way, 2-position, solenoid-operated directional spool valve rated up to 350 bar at 1 l/min but weighing just 58 gm and measuring only 61 mm high. Because it connects to an industry-standard controller, it is a small solution that delivers big results in existing applications; and with a typical response time of 10 ms with reduced power consumption, it opens up opportunities to drive new high performance designs in mobile and industrial applications.
Get small
Who doesn’t want improved performance and reduced size for their fluid power applications? The DLV range brings together new technology and innovative design that does just that, employing a micro-solenoid with optimised magnetics and a small, top-mounted M12 connector to drive down size and weight, simplify the wiring of the components and reduce the amount of space required for a multi-valve integrated package.
The DLV family has a significant advantage over the standard DAAL 2-way, 2-position directional spool valve in an integrated package. Not only is it possible to shrink the cartridge face on the manifold by 42%, but with the space-saving connector and wiring configuration and the lower overall height of the valve, the space required to accommodate the total package is dramatically smaller as well; and with the proper M12 mating cable, the connector is rated to IP69K for demanding mobile applications.
Go faster
In fluid power, a digital valve is a two-state component that can switch states (on or off) so fast that the transition between states is negligible. Used as a logic element, the DLV – with its shift speed measured in milliseconds – can be used for directional control, pressure control or flow control. This fast response means machine productivity can be increased with significantly reduced cycle times.
The DLVB, with 10 ms typical response time, is two times faster than Sun’s DAAA and four times faster than the DAAL – both 2-way, solenoid-operated directional spool valves.
Use less
Optimised magnetics and the use of a micro-solenoid mean the DLV coil typically draws only 2 W hold and 15 W peak – a power saving of up to 90% over the standard DAAL with a 22 W coil. This means the DLV offers higher performance with a lower current draw and lower heat generation.
Think big
By leveraging Sun’s T-8A cavity concept that provides for a standard screw-in pilot for a main-stage cartridge, the small, fast DLVB can be used to build a customised control solution using standard components, opening up a wide range of opportunities for this high performance cartridge.
Sun offers many standard products – including relief, directional and flow control valves – in a range of capacities up to 1100 l/min with an integral T-8A cavity. This means that this small solution can provide big results in an off-the-shelf solution. Imagine this tiny 58 gm valve controlling 875 hydraulic horsepower.
A small solution that delivers big results
With its innovative design and few moving parts, the new DLV family expands your design options and helps create smaller, highly reliable solutions where size and performance matter.
The product launch includes four versions with 12 or 24 V DC coils in a normally open or normally closed configuration. As with any high performance cartridge valves, system cleanliness and proper filtration is required for optimal performance, and a version of this product with a built-in filter will be available soon.
