Accumulator Valve 35-40PSI

The MOROSO Accumulator Valve 35-40PSI is a precision oil pressure control system designed for high-performance engine management in racing and modified street applications. This 12V pressure control valve regulates oil accumulation in systems where consistent pressure stability is critical to engine longevity and performance. The 35-40 PSI operating range provides balanced protection for engines running elevated performance profiles without sacrificing bearing load capacity or oil delivery efficiency.

The valve features 1/2 inch NPT female ports, making it compatible with standard plumbing and hose adapters found in most oil system configurations. The complete kit includes the accumulator valve body, pressure control switch, electrical wiring harness, and all necessary fittings—eliminating the need to source components separately. At 1.9 lbs and compact dimensions of 4.4 x 4.3 x 5.6 inches, this unit integrates easily into tight engine compartments without requiring substantial modifications to existing oil circulation systems.

This accumulator valve is engineered for engine builders and performance enthusiasts running forced-induction platforms, turbocharged or supercharged mills, or naturally aspirated engines with elevated RPM capability. Oil accumulators serve a critical function by maintaining minimum oil pressure during cold starts, high-acceleration events, and transient demand spikes—conditions where traditional gravity-fed systems momentarily starve bearings. The pressure-regulated design prevents over-pressurization while ensuring adequate film strength across the entire operating envelope, extending component lifespan and reducing catastrophic failure risk in high-stress environments.

MOROSO's reputation in engine accessory manufacturing reflects decades of experience supplying professional racing teams and OEM manufacturers. The 35-40 PSI threshold represents a proven specification for small-block and mid-sized displacement engines; larger displacement or multi-turbo platforms may require alternative pressure settings. Proper installation includes flushing all components before assembly and verifying electrical continuity of the switch circuit prior to engine startup.
