Brand Replacement Reference

For aftermarket applications, the P40SD-AT can be marketed as a Replacement, Compatible Replacement, or Aftermarket hydraulic valve for compatible applications.

When replacing a valve from another manufacturer, compatibility should be evaluated based on the complete original valve specification rather than the model number alone. Important factors include hydraulic function, spool configuration, pressure rating, flow requirement, port configuration, mounting dimensions, and control method.

Compatibility Verification

Before purchasing a P40SD-AT replacement valve, it is recommended to verify:

• Complete original valve model

• Original valve nameplate

• Equipment brand

• Equipment model

• Equipment serial number

• Valve function

• Spool configuration

• Number of valve sections, if applicable

• Rated flow

• Working pressure

• Inlet port size

• Outlet port size

• Work port size

• Thread standard

• Mounting dimensions

• Control method

• Hydraulic circuit configuration

• Original hydraulic schematic

If the customer can provide the original valve nameplate, complete model number, equipment model, hydraulic schematic, or product photos, further replacement compatibility can be evaluated.

Compatibility Note: Actual replacement suitability depends on the complete valve configuration, hydraulic pressure, flow rate, spool function, port specifications, control method, mounting dimensions, and equipment hydraulic circuit. Direct interchangeability should not be determined solely by the “P40SD-AT” model designation.
