Assured durability: Sprayer Pressure Release Valve is made of quality PP material, resistant to deformation and designed for dependable, stable performance over longterm use. Improve work efficiency: The pressure relief valve helps maintain pressure in knapsack sprayers, reducing manual effort and saving time during spraying tasks. Protect the bottle body: When the pressure exceeds a set value, the valve automatically deflates to prevent overpressure and protect the bottle body. Easy to install: This valve can directly old or damaged air release valves; simple to install and remove, improving overall stability. Key attributes Function: pressure relief with automatic deflation at overpressure to safeguard the sprayer Compatibility: designed to directly old or damaged air release valves in knapsack sprayers Material: quality PP Performance: durable, deformationresistant, stable for longterm use Use scenarios Garden and lawn care: a worn valve in a backpack sprayer to ensure safe operation, consistent pressure, and efficient spraying during routine yard tasks. Agricultural applications: suitable for knapsack sprayers used in orchards, fields, or greenhouses, providing reliable pressure relief during extended spraying sessions. Pest control and fertilization at home or small farms: helps maintain safe pressure levels and reduces maintenance downtime by enabling quick replacement of the old valve.
