The Relief Valve BXF-25 is installed on the hydraulic block of the hydraulic servo motor. Its main function is to make the pressure oil in the lower chamber of the piston of the hydraulic servo motor be released quickly through the unloading valve when the emergency trip device acts to make the ast oil lose pressure when the unit fails, so that the valve can be closed under the action of spring force.
