Abstract
A spring-operated relief valve can include a main spring positioned between a bottom spring seat and a top spring seat. A seat assembly can include a valve seat, a seat retainer, and a spindle. The valve seat and the spindle can be received within an inner bore of the seat retainer and the spindle and the seat retainer can be threadably coupled. The valve seat can extend partially through the seat retainer to form a seal with a nozzle of the spring-operated relief valve and the spindle can engage the bottom spring seat to compress the main spring during a valve relief event.
