Pin Guide / Locating Guide (Part No. 520000764)
Product Name: Pin Guide / Locating Guide (Part No. 520000764)
Description:
This component is a pin guide, also known as a locating guide or bushing, designed for precision alignment in waterjet cutting systems, specifically within the on/off valve assembly. It is a precision-machined cylindrical component that guides valve stems or other moving parts, ensuring proper positioning and smooth operation. It is typically manufactured from hardened steel or bronze to provide a low-friction bearing surface and maintain component alignment under high-cycle operation.
Applications:
Provides precise alignment between mating components in valve assemblies and mechanical linkages
Guides moving parts (such as a valve stem or poppet) to maintain concentricity and prevent binding
Serves as a locating element to ensure proper assembly positioning
Specifically used as a component (EWV0011) in the on/off valve assembly of waterjet cutting systems
Features:
Precision-Machined Geometry: Manufactured to exact dimensional tolerances for accurate fit and smooth operation
Wear-Resistant Material: Constructed from hardened steel or bronze for durability under high-cycle operation
Low-Friction Surface: Provides a smooth bearing surface to minimize wear on mating components
Corrosion-Resistant: Treated to withstand moisture and abrasive dust exposure in waterjet environments
Steel Construction: As specified in manufacturer documentation
Maintenance:
Inspection: Periodically examine the pin guide for signs of wear, scoring, galling, or surface damage
Dimensional Check: Measure the internal diameter to detect wear beyond manufacturer-specified limits
Bore Condition: Inspect the internal bore for scratches, grooves, or uneven wear patterns
Replacement Criteria: Replace immediately if visible wear, scoring, or deformation is detected
Set Replacement: Replace as part of a complete on/off valve repair kit (including seat, seal guide, sealing ring, needle, seal, and pin guide) for optimal performance
Installation: Ensure the housing bore and pin guide are thoroughly cleaned before installation; verify proper seating
Lubrication: Apply high-pressure grease during reassembly to ensure smooth operation and prevent dry startup
Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before servicing
