16、 Special Soft Shift Cartridge)A fire truck OEM wanted a “soft shift” valve with about a one second (1000 ms) ramp time in order to give a smooth stop to rotation when the valve is de-energized.Can we use a proportional valve with a deceleration ramp? No. Amplifiers can not ramp when power is removed

17、!26Results with Standard and Modified Soft Shift ValvesThe first attempt, with a DLDA-SHN yielded a 1/3 second (300 ms) ramp time. The second attempt, with an FPCH-MBN plus a soft shift solenoid, yielded a 1.20 second (1200 ms) ramp time.27Distributor Support28Helping OEM Customers Maintain Their Af

19、highest priority, but we will not “steal” from previously scheduled orders.Orders are entered with your request date as the goal (The actual day is entered, not the week.)Dont forget, Sun measures their overall delivery performance against your request date, not against some date generated internall

Youll never get the “cold shoulder” when asking for some help at Sun.However, your first contact should be to your in house technical “

21、go-to” person. Based on the nature of the question, he or she is the one that should be the most up to date as regards who would be the best contact at Sun.31 17 Updated and New Technical Tips are now on the Sun Web Site32When Theres No Choice But To Usea Competitors CartridgesSuns Manifold Design G
