The spray system pressure relief valve is a non ad-
justable, non repairable component. When spray sys-
tem pressure exceeds the pressure limit of 218 PSI (15
Bar), the valve opens and spray product is directed to
the spray tank. Replace the pressure relief valve if sys-
tem pressure exceeds the pressure limit (valve not
opening), or if desired system pressure near the pres-
sure limit is not attainable (valve not closing).
