| description | A hydraulic system provides failure protection by incorporating an isolator adjacent a hydraulic actuator. The isolator has a first port connected to the hydraulic actuator and a second port with an electrically operated isolation valve connected between those ports. A pressure relief valve responds when pressure in the hydraulic actuator exceeds a given level by relieving pressure thereby enabling the isolation valve to open without application of electricity and release the pressure in the hydraulic actuator. A control valve assembly is remote from the hydraulic actuator and connected to the second port for metering flow of fluid between a source and the hydraulic actuator. |
