Sun Hydraulics Corp.’s (Sarasota, FL) solenoid-operated digital logic valve (DLV) paves the way for smaller, highly reliable solutions in demanding mobile applications where size, weight, speed and power matter and in industrial applications where an incredibly fast valve can help reduce machine cycle times. According to the company, the DLV is the industry’s smallest high-speed, reduced-power logic valves. The first product introduced in the DLV family, the DLVB is a fast two-way, two-position, solenoid-operated directional spool valve rated up to 5000 psi (350 bar) at 0.25 gpm (1 L/min) but weighing just 2 oz (58 g) and measuring 2.2 in (57.2 mm) high. Because it connects to an industry-standard controller, it is a small solution looking to deliver big results in existing applications. 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.
