Ultramax Systems supplies replacement stainless steel springs for the 1/4 inch hard seat safety relief valves in this range. The spring sets the pressure at which the valve lifts, so fitting a fresh spring during service keeps the valve relieving at its correct set point. Stainless steel resists corrosion and fatigue for repeatable operation. These springs are held in Australian stock. Keeping a spare spring on hand shortens valve downtime during service. Each spring is matched to the original valve specification for a like-for-like fit.
