Built to last: made from quality polypropylene (PP) that resists deformation and delivers stable, longterm performance. Durable construction reduces the need for frequent replacements. Protects your equipment automatically: the builtin safety release function vents excess pressure when it exceeds a safe level, preventing damage to the sprayer bottle and internal components. Saves time and improves work flow: by preventing overpressure and allowing consistent spray performance, the valve helps you finish jobs faster with fewer interruptions. Easy replacement and maintenance: designed for convenient installation and removal so you can quickly swap it in for an old or damaged valve and restore reliable operation. Broad compatibility: intended for use with knapsack and garden sprayers that use this style of pressure relief valve. Check your sprayer's valve seat and mounting style to confirm fit before . Reliable performance: consistent pressure relief behavior reduces the risk of sudden pressure spikes, improving safety and the lifespan of your sprayer. Typical use scenarios Applying fertilizers, pesticides, or herbicides with a knapsack sprayer: prevents overpressure during prolonged use and protects the tank from stressrelated cracks or leaks. Foliar feeding or garden maintenance with a handheld or backpack sprayer: maintains steady performance and reduces downtime for manual pressure checks. General outdoor cleaning and chemical application tasks where controlled pressure and equipment protection are needed. What you get A durable PP safety/pressure relief valve that replaces worn or damaged valves to restore safe, reliable sprayer operation. Designed to provide automatic protection and improve overall working efficiency.
