An empty-load device, having in a single housing, a sensing piston and a ratio piston interconnected by a push rod which senses load. A ratio valve, including a valving element and valve seat, is mounted on and travels with the ratio piston and is opened by the push rod. The ratio valve is connected to the ratio piston by a spring such that the push rod engages the ratio valve to open the ratio valve and position the ratio piston via the spring.
