SUN HYDRAULICS 2-way, soft shift, solenoid-operated directional spool valve (DLDASHN)

This solenoid-operated 2-way, 2-position cartridge is a direct-acting, balanced spool valve with a soft shift feature. The soft shift feature greatly reduces system shock due to valve actuation. The valve is available in either a normally open or normally closed configuration.

• The soft shift cartridge is interchangeable with the standard cartridge, however, the performance limits are lower.
• The soft shift feature can greatly reduce shock due to valve actuation but should not be counted upon in applications where timing is critical. If you need accurate ramping or timing control, consider Sun’s electro-proportional valves.
• The soft shift feature results in significant increase in response time over Sun’s standard solenoid. Response time is dependent on flow, pressure, coil voltage, oil viscosity and ambient temperature. Typical response time ranges from 150 ms to 300 ms.
• For consistent soft shift performance, port 1 should be at a positive pressure.
