- Set Pressure and Temperature Ratings
- Inlet and Outlet Flange Sizes
- National Board (NB) or ASME Certification Marks
03
Review factors
Condition, documents, and value context
Condition
Assess the seating surfaces for pitting, scoring, or corrosion, as compromised seals prevent proper pressure relief. Check the spring mechanism for fatigue or rust, and verify that the external housing is free from physical impact damage.
Documentation
Provide original manufacturer test reports, recent calibration certificates, maintenance logs, and any documentation of ASME or National Board certification.
Evaluation context
General evaluation considerations include the brand reputation, exact pressure and temperature ratings, the presence of verifiable testing documentation, and the overall physical integrity of the valve components.
04
Freight and site facts
Plan around the real load and access conditions
Safe transport requires securing the valves upright on heavy-duty pallets with adequate padding to protect sensitive spring mechanisms and flanges during transit.
Equipment-source context to document
- Facility maintenance stores and project surplus
- Shutdown, upgrade, or decommissioning inventory
- Contractor, distributor, and warehouse-held surplus
Loading details to share
- Equipment dimensions and weight
- Pallet or skid condition
- Forklift, crane, or dock access
- Gate, appointment, and site restrictions
