Ultramax Systems supplies unset stainless steel replacement springs for the 3/4 inch hard seat safety relief valves in this range. Unset springs are supplied uncalibrated, so the valve can be set to the exact relief pressure the application needs. The spring sets the pressure at which the valve lifts, and stainless steel resists corrosion and fatigue for repeatable operation. Matching the spring to the valve size keeps overpressure protection dependable. These springs are held in Australian stock. Keeping a spare spring on hand shortens valve downtime during service.
