Why fit this signal shuttle valve

• Lapped sealing surfaces - so the spool holds pressure without internal bypass.
• Correct spool geometry - meters flow the way the original does, no jerk or drift.
• Drops straight in - same bore, same ports, same control arrangement.
• Inspected before packing - bore and sealing faces checked, movement verified.

Signs this signal shuttle valve needs replacing

• One function slow or dead - while the others work normally.
• Drift or creep - with the lever in neutral.
• Jerking or chatter - when the function is operated.
• Overheating - or low pressure on the affected circuit.

If your ZX200 shows any of these signs, replacing the part is the fastest way back to full production.

Installation notes

• Clean the area before opening the valve block, one grain of grit scores a spool.
• Check the pilot pressure and relief setting before replacing the valve.
• Lubricate the spool with clean oil and check it moves freely by hand.
• Test each function at low load, then check for external leaks.
