Frequently Asked Questions
Q: What is the BI 12003473 hydraulic valve and what does it control?
A: The BI 12003473 is an OEM hydraulic control valve manufactured for Bishamon Blue Label BS Series manual pallet jack hydraulic units. This valve regulates lift, lower, and neutral hydraulic functions, enabling the operator to control platform height through the original control linkages.
Q: Which Bishamon models are compatible with the BI 12003473 valve?
A: The BI 12003473 is engineered for direct replacement in Bishamon BS-55 Series pump assemblies. Alternate model designations are BS55 and BS 55. This valve is not compatible with other pallet jack brands or Bishamon model lines.
Q: Are there alternate part numbers for the BI 12003473?
A: No cross-reference part numbers have been identified for the BI 12003473. It is an exclusive Bishamon OEM component. Order using the primary SKU BI 12003473 to receive the correct valve for your BS-55 pump assembly.
Q: What happens if the BI 12003473 control valve fails?
A: A failed BI 12003473 valve will result in loss of lift control, inability to raise or lower the platform, or uncontrolled lowering. The pallet jack will be unsafe to operate and require immediate valve replacement to restore proper hydraulic function.
Q: How does the BI 12003473 valve integrate with the control linkages?
A: The BI 12003473 valve is designed for installation into the Bishamon BS-55 Series pump assembly hydraulic circuit. It interfaces with the original control linkages and directional controls, allowing the operator to command lift, lower, or neutral functions without modification to existing controls.
Q: What operating pressure range does the BI 12003473 valve support?
A: The BI 12003473 valve operates up to the rated hydraulic system pressure of the Bishamon BS-55 pallet jack. The valve is engineered specifically for this pressure range and should not be used in systems exceeding Bishamon specifications.
