20100294375 | SPEED CONTROL VALVE SYSTEM - A speed controller valve system for regulating an opening speed and a closing speed of a pressure reducing valve includes a first inlet couplable to a main valve inlet of a pressure reducing valve. An outlet is couplable to a power chamber of the pressure reducing valve to control a flow of fluid between the outlet and the power chamber to control an opening and/or a closing of the pressure reducing valve. An interior chamber connects the first inlet and the outlet. The chamber receives a resilient member connected to a tapered valve poppet received in the first inlet and moveable in response to a flow of fluid at a pre-set pressure from the main valve inlet to the first inlet. The poppet is located in the chamber and the resilient member includes a resiliency to regulate an amount of movement of the poppet at the pre-set pressure to regulate a flow between the first inlet and the power chamber of the pressure reducing valve. | 11-25-2010 |
