PM-43P

Frequently Asked Questions

Q: What equipment does the PM-43P overload valve fit?
A: The PM-43P is an overload valve designed as a direct fit for Palletmaster model 6600 manual pallet jacks. It is a sealed relief component in the hydraulic circuit and is not interchangeable with other pallet jack brands or models without verification of hydraulic system specifications.

Q: What is the function of the PM-43P overload valve?
A: The PM-43P overload valve protects the hydraulic pump and cylinders from overpressure conditions. When system pressure exceeds the valve setpoint, it opens to route excess fluid back to the reservoir, preventing component damage and maintaining safe operation.

Q: How do I know if the PM-43P needs replacement?
A: Signs of a failing PM-43P include reduced lift height, inability to reach full load capacity, fluid leaking from the valve body, or the jack continuing to lower under full load when parked. If any of these symptoms occur on a Palletmaster model 6600, the valve should be inspected or replaced.

Q: Is the PM-43P available with alternative part numbers?
A: Cross-reference your equipment documentation for superseded or equivalent part numbers specific to your Palletmaster model. Contact our parts team with your serial number to confirm exact compatibility and any alternate SKUs.
