| description | The disclosure provides devices and methods for controlling the actuation rates of SPM valves by bi-directionally controlling the fluid which actuates the valve or by maintaining enclosed volumes which communicate with each other thru predetermined restrictions (78) as the valve actuates. These enclosed volumes can be completely isolated, depth compensated, share fluid with the pilot actuating fluid, or utilize the main system fluid. The restrictions can be modified to increase or decrease the actuation rates of the SPM valve. The disclosure also provides control over the main system fluid passage opening and closing positions as well as how rapidly the flow passage areas increase or decrease while opening or closing the valve. |
