Heavy-duty priority flow control valves provide a simple and efficient way to supply auxiliary hydraulic power to mobile work tools and attachments, such as hydraulic impact hammers, compactors, saws, and cold planers. The valves mount to existing hydraulic systems without modifying a machine’s directional-control valve. Also called “hammer valves,” they are available for single-pump, doublepump, or load-sensing systems. A three-way configuration includes one pump inlet port and two outlet ports for priority and by-pass flow. This permits simultaneous operation of both the hydraulic actuator and normal machine functions.
