| 20110220206 | VALVE FAULT INDICATION AND CONTROL - According to aspects described herein, there is disclosed a method of and system for indicating a fault associated with a fluid valve moveable between an open and a closed operative position. The method and system compare a valve state indicator to a valve last command, wherein the valve state indicator represents a detected operative position of the valve and the valve last command being an operative command sent to the fluid valve. The method and system also initiate a fault indication after a predetermined time delay relative to the valve last command being sent and when the valve state indicator does not match the valve last command. After the time delay a fault indication can be initiated immediately upon receipt of a different valve state indicator. | 09-15-2011 |
| 20090314355 | SQUIB VALVE ASSEMBLY - The present invention includes a valve assembly having a fluid flow passage, a piston passage, a closure element and a moveable piston. The fluid flow passage extends from an inlet port to an outlet port. The piston passage transects and is oriented non-parallel to the fluid flow passage. The closure element interrupts fluid communication between the inlet and outlet ports. The piston being moveable within the piston passage between a first and second position, the piston including a head for opening the closure element wherein movement of the piston between the first and second positions enables fluid communication between the inlet and outlet ports. The valve assembly can include an explosive actuation mechanism for rapid actuation of the piston from the first position to the second position. | 12-24-2009 |
