What is the purpose of a relief valve in a hydraulic sprayer?

Explanation:
Relief valves are there to keep the hydraulic sprayer from over-pressurizing. When the pump pushes liquid at high pressure, a blockage or closed nozzle can cause pressure to spike. The relief valve opens at a predetermined setting and routes some flow back to the tank or into a bypass line, keeping system pressure at or below the safe limit. This protects the pump, hoses, seals, and fittings from damage and helps ensure reliable, safe operation. It’s not meant to increase flow, adjust nozzle size, or filter the spray solution.
