Designed for the ZAXIS 210/240, the 4276584 check valve zaxis 210/240 manages hydraulic fluid direction and pressure to ensure safe, controlled operation of the machine's hydraulic circuit. A worn or faulty valve causes hydraulic drift, pressure loss, and unpredictable machine behaviour — creating safety risks during lifting, digging, and load-handling operations. Manufactured to OEM reference 4276584 for accurate fitment and immediate hydraulic performance on the ZAXIS 210/240.

Key Features:

  • Backflow Prevention: Prevents hydraulic fluid reverse flow to maintain circuit integrity and directional control.
  • OEM Specification: Manufactured to reference 4276584 for accurate fitment on the ZAXIS 210/240.
  • Leak-Free Design: Precision-manufactured sealing surfaces prevent internal and external hydraulic leakage.

The 4276584 check valve zaxis 210/240 is a critical hydraulic control component for safe, stable machine operation on the ZAXIS 210/240.

What Does This Check Valve Assembly / Spool Cap Do?

A check valve allows hydraulic or fuel fluid to flow in one direction only, preventing reverse flow that would cause loss of circuit pressure or function drift. Spool caps seal the ends of hydraulic control valve spools and retain the centring springs that return the spool to neutral when the operator releases the control lever.

Possible Check Valve Assembly / Spool Cap Problem Symptoms

If your machine is showing any of the following, a faulty check valve assembly / spool cap may be the cause:

  • Hydraulic function drifting or dropping slowly when the control lever is in the neutral position
  • Loss of holding pressure in a boom, arm, or attachment circuit when controls are released
  • Spool cap leaking hydraulic oil externally at the end of the control valve body
  • Hydraulic function not returning to neutral — remaining active after the lever is released
