RELIEF VALVE

When system pressure reaches the valve’s set point, it opens to divert excess flow back to the reservoir, preventing damage. This valve is commonly used on heavy-duty trucks and trailers with hydraulic systems such as dump bodies, roll-off hoists, and cranes. It features an adjustable setting, in-line mounting, 1-inch NPT ports, and a 60 GPM flow rating. The -3000 suffix likely indicates a 3000 psi relief pressure setting, though this could not be independently verified from the manufacturer’s published series specs.
