Product Overview
The Parker R4V06 533 30 11G0Q A1 (OEM Reference: 056-40464-H) is a high-performance pilot-operated pressure relief valve engineered within the renowned Parker R4V series of hydraulic pressure control valves. This valve functions as a critical safety and pressure-regulating component in industrial hydraulic systems, utilizing a two-stage pilot-operated design to limit system pressure to a predetermined safe level. When system pressure reaches the adjustable set point, the pilot stage opens, causing an unbalanced force on the main poppet, which then lifts to divert excess flow to the reservoir. This design ensures fast response, minimal pressure override, and stable operation even under high flow conditions. The R4V06 is a direct-fit replacement for OEM part 056-40464-H, offering precise pressure control for demanding industrial applications.
