This results in a higher performance limit at the expense of lowercapacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.■The soft shift feature results in significantly longer response time over Sun’s standard solenoid. Response time is dependant on flow, pressure,coil voltage, oil viscosity and ambient temperature. Typical response time ranges from 150 ms to 300 ms.■A wide variety of coil termination and voltage options are available.
