Numerous body styles and thread types are available for your convenience. And, we can work to match your precise application requirements for Open Pressure, Reseal Pressure, or Flow Rate.

SEDCO’s ball-style relief valve prevents air conditioning compressor and component damage by venting excessive high temperature discharge pressure directly on to a thermal overload which trips and prevents motor failure.
