Parker A4N0231D1K Piston Accumulator 231 In3

Product Description

The PARKER A4N0231D1K is a piston-type hydraulic accumulator designed to store and release hydraulic fluid energy in industrial and mobile hydraulic systems. Pre-charged with gas, it maintains system pressure, absorbs shock, dampens pulsation, and supplements pump flow during peak demand cycles. With a fluid capacity of 231 cubic inches and a gas capacity of 241 cubic inches, this unit handles substantial flow demands up to 397 GPM. The SAE 20 port thread provides a secure, standardized connection to hydraulic circuits. Licensed hydraulic technicians and mechanical contractors install this type of component in high-pressure fluid power systems.

This accumulator is suited for industrial hydraulic circuits where energy storage, pressure maintenance, or shock dampening is required. Its any-position mount type gives installers flexibility in tight or unconventional mounting environments. The unit ships pre-charged, reducing commissioning time on new installations and direct replacements. Typical applications include hydraulic power units, press systems, mobile equipment hydraulics, and industrial machinery requiring flow supplementation or emergency pressure reserve.

Key Features

• Pre-charged from the factory, ready for installation without additional gas charging equipment in most setups
• 231 cubic inch fluid capacity supports high-volume hydraulic energy storage
• Maximum flow rate of 397 GPM handles demanding peak-flow applications
• SAE 20 port thread provides a standardized, leak-resistant hydraulic connection
• Any-position mount type allows flexible installation orientation
• Overall height of 4.75 inches supports compact system layouts

Compatibility

Designed as an OEM-style piston accumulator for industrial and mobile hydraulic systems requiring SAE 20 port connections and a 231 cubic inch fluid capacity.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with high-pressure fluid power systems. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any accumulator. Verify the pre-charge gas pressure against system design specifications before commissioning. Follow all applicable industry safety standards for hydraulic accumulator installation, including proper pressure relief provisions and secure mechanical mounting.
