Valve, Maximum with Restricted Flow
SAF-Holland

Within heavy duty vehicle braking and control networks, this restricted-flow valve functions as a protective control device that limits process fluid or air passage to downstream components. The design regulates maximum throughput, shaping pressure rise and decay to suppress surges, reduce wear on solenoids and actuators, and maintain consistent operation under varying loads. The device complements SAF-Holland hydraulic and pneumatic assemblies by providing predictable response characteristics in critical circuits such as air brake systems, trailer control lines, and auxiliary circuits. With a VMRS code that identifies it as a pressure-control valve, it integrates with common SAE port sizes and mounting conventions, promoting straightforward replacement and interchangeability in compatible fleets. Benefits include improved system stability, longer service life for valves and actuators, and easier fault diagnosis due to known flow limits. The component supports modular maintenance programs, enabling technicians to isolate problems to the valve without affecting upstream controls. In applications where brake pressure or load fluctuations can trigger spikes, the restricted flow helps preserve seals, manifolds, and reservoirs. This part’s category context places it among critical safety and control elements used across truck and trailer hydraulic and pneumatic circuits, ensuring compatibility with the broader SAF-Holland ecosystem and standard VMRS-driven maintenance documentation.
