Abstract
An apparatus for bleeding or purging fluid from a fluid line includes a bleed valve permanently affixed to the wall of the fluid line and a valve actuator releasably connected to the bleed valve which is operative to move a spring-biased, one-way valve member in the bleed valve between a valve open and valve closed position. The valve actuator is movable to a valve open position relative to the one-way valve member in response to the spring force exerted by a coil spring or the like, which avoids damage to the biasing spring associated with the one-way valve member. The valve actuator also includes a guard to prevent assembly or disassembly of the valve actuator and bleed valve with the valve actuator in a valve open position.
